List of Top 5 Best Battery for 2017 Kia Forte in 2027
We kept this list to batteries with a clean group-size match and enough documented buyer feedback to spot patterns. Each entry gets the same treatment: what the spec sheet says, what owners actually report, and where the battery stops making sense for your Forte. No filler, no hype.
Below are the list of products:
1. Weize Platinum AGM Battery Group 48
Weize's Platinum line keeps surfacing in owner threads for a simple reason: it delivers a full AGM spec sheet without premium-tier pricing. Group 48, also sold as H6, is one of the more common footprints on compact Kia and Hyundai models, which makes it the logical first stop for a 2017 Forte.
Why I picked it
Buyer feedback on this case size is unusually consistent: cranking stays strong through the second and third winter, and terminal corrosion shows up less than on cheaper flooded units. The 760 CCA figure is also real headroom for a 1.8L or 2.0L four-cylinder that only needs around 500 to 600 CCA to spin over.
Key specs
- 12V AGM with 70Ah rated capacity
- 760 cold cranking amps at 0°F
- Group 48 (H6) case, roughly 11 inches long
- Sealed maintenance-free design, no water top-ups
- Works with the 13.8V to 14.4V charging window most 2017-era alternators hold
Real-world experience
Cold-climate owner reports describe clean starts in single-digit Fahrenheit mornings, and dashcam users say parking-mode draw doesn't strand them after a weekend. Short-trip city drivers are the ones who notice the fastest voltage recovery after a jump, which tracks with how AGM handles a partial state of charge.
- 760 CCA paired with 70Ah leaves real headroom for a 2.0L Forte and its accessory load.
- Group 48 is a widely stocked footprint, so a warranty swap is easy to find anywhere.
- Sealed AGM means no distilled water top-ups and slower terminal corrosion.
- Owners in sustained extreme heat report capacity fade earlier than the four-year mark.
- It’s heavier than the flooded battery it replaces, so check the hold-down and tray.
- It’s a starting battery, not deep cycle, so don’t plan on running accessories flat.
- ✔ Your 2017 Forte specs a Group 48 or H6 case
- ✔ Your winters dip below freezing and you want cranking margin
- ✔ You run a dashcam or another small always-on accessory
- ✖ Your existing label shows a 24F, 35, or 140R group size
- ✖ You need a deep-cycle battery for off-grid gear
2. OPTIMA® Batteries High Performance DH5 YELLOWTOP®
OPTIMA's YELLOWTOP line sits in a different category from everything else here. It's a dual-purpose AGM built to take repeated deep discharges and still start the car, which is why it keeps turning up in builds with audio gear, winches, and long accessory runs.
Why I picked it
It carries the highest reported rating on this list at 4.6 out of 5, and the recurring theme in buyer feedback is recovery after being run flat. For a Forte owner who has killed a battery twice with a subwoofer or a forgotten dashcam, that behaviour matters more than a bigger cranking number.
Key specs
- Group 35 (DH5) case footprint
- Sealed absorbed glass mat (AGM) construction
- Dual-purpose design rated for starting plus repeated deep cycling
- Spiral-wound plate architecture built to resist vibration
- Maintenance-free with no electrolyte checks
Real-world experience
Reports from car audio and overlanding setups describe the battery bouncing back after being drained to a point where a standard starting battery would need a charger and luck. In a plain daily-driver Forte with no accessories, most owners won't notice the difference over a cheaper AGM, and that's the honest trade.
- Handles repeated deep discharges far better than a starting-only AGM, which is the whole point of the line.
- Highest reported buyer rating here at 4.6 out of 5, with praise centred on recovery after drain.
- Sealed case resists vibration and tolerates mounting angles a flooded battery can’t.
- Premium tier pricing, and a commuter Forte won’t use half of what you’re paying for.
- It isn’t the highest cranking option here, so it’s the wrong pick for brutal cold if CCA is your priority.
- ✔ You’ve drained a battery before and don’t want to repeat it
- ✔ Your Forte carries audio gear or camping accessories
- ✔ Your tray takes a Group 35 footprint
- ✖ You just need a straightforward commuter battery
- ✖ You face minus-20°F mornings and want maximum CCA
3. Weize Platinum AGM Battery Group 24F
Group 24F is the size a lot of Kia and Hyundai four-cylinder cars actually ship with, and it's the tighter budget path if that's what your existing label says. Same Weize Platinum chemistry as the winner, slightly less cranking power, smaller case.
Why I picked it
The 24F case is a common factory fit on this generation of compact Kia, and 710 CCA is roughly 110 amps above what a 1.8L four-cylinder needs to crank in cold weather. That combination makes it the sensible budget answer rather than the cheapest one available.
Key specs
- 12V AGM rated at 70Ah
- 710 cold cranking amps
- Group 24F case with reverse terminals
- Sealed maintenance-free construction
- 12.9V to 13.0V resting voltage when fully charged
Real-world experience
Verified buyer feedback from short-trip commuters notes that this battery holds voltage better than the flooded OEM unit it replaced, mainly because AGM accepts charge faster on a 15-minute drive. Towing or winching will drain it quickly, but that's outside what it's designed for.
- 710 CCA covers a 1.8L or 2.0L Forte with room to spare on cold mornings.
- Group 24F is a true drop-in for cars originally fitted with that case size.
- Budget-friendly without dropping to a flooded lead-acid design.
- 50 fewer CCA than the Group 48, so cold-weather margin is smaller.
- Reverse-terminal layout trips up first-timers who don’t check before buying.
- ✔ Your Forte’s label reads Group 24F
- ✔ You want AGM behavior on a tight budget
- ✔ You drive mostly short city trips
- ✖ Your tray takes Group 48, 35, or 140R instead
- ✖ You want the most cold cranking amps you can get
4. Weize Platinum AGM Battery Group 140R
Group 140R, also labeled H4, is the small-case option here at 570 CCA. It exists for a reason: some Forte trims and later-year variants use a shorter tray, and cramming a bigger battery in isn't an option.
Why I picked it
Fit beats specs when the tray is small. This earns a place because 570 CCA is still enough for a naturally aspirated four-cylinder, and the compact H4 case solves a problem the bigger batteries physically can't.
Key specs
- 12V AGM in a Group 140R (H4) case
- 570 cold cranking amps
- Short-case footprint for tight trays
- Sealed maintenance-free AGM build
- Suited to 1.6L to 2.0L four-cylinder engines
Real-world experience
Aggregate owner reports show it handling mild-climate starts without complaint, and the small case makes installation in tight engine bays noticeably quicker. Where owners push back is extreme cold: below zero, the lower CCA count leaves less margin than a 760 CCA unit would.
- Fits trays where a Group 48 or 24F physically won’t go.
- 570 CCA is adequate for a naturally aspirated four-cylinder in normal conditions.
- Light enough to lift in and out without help.
- Lowest cranking amps on this list, so severe cold is its weak spot.
- Fewer reserve minutes, which shows up if you leave lights on.
- ✔ Your tray is sized for H4 or 140R
- ✔ You live somewhere winters stay mild
- ✔ You want a light battery you can install solo
- ✖ You regularly start the car below 0°F
- ✖ Your tray has room for a bigger case
5. Weize Platinum AGM Battery Group 35
Group 35 rounds out the list as the middle child: 650 CCA, 55Ah, and a case that fits a long list of Asian-brand compacts. If your Forte's original battery was a 35, this is the closest like-for-like AGM replacement.
Why I picked it
It earns its slot on compatibility rather than raw output. Group 35 appears across a wide spread of compact cars, so a buyer who isn't sure of their group size often lands here, and 650 CCA is enough for a stock Forte without being overkill.
Key specs
- 12V AGM with 55Ah capacity
- 650 cold cranking amps
- Group 35 case footprint
- Sealed, maintenance-free AGM design
- Fits a broad range of Asian-brand compact cars
Real-world experience
Verified buyer feedback points to solid performance in three-season driving, with the caveat that 55Ah means less reserve when the car sits idle for long stretches. Owners who drive daily report normal voltage hold; owners who park for two weeks often add a maintainer.
- Group 35 fits a wide spread of compact cars, so sourcing a replacement is easy.
- 650 CCA is a comfortable match for a stock naturally aspirated Forte.
- Sealed AGM build means no water checks for the life of the battery.
- 55Ah is the smallest capacity here, so reserve time is limited.
- Not the right fit if your tray is actually sized for 48, 24F, or 140R.
- ✔ Your OEM battery was a Group 35
- ✔ You want a straightforward like-for-like swap
- ✔ You drive the car most days of the week
- ✖ The car sits parked for weeks at a time
- ✖ You need maximum reserve capacity for accessories
How I picked
Battery shopping is mostly a fit-and-spec problem dressed up as a brand debate, so we started there. Our editorial team compared manufacturer datasheets across all five models, then cross-checked those numbers against aggregated owner feedback for the same case sizes. No lab bench, no dyno, just disciplined spec matching.
Here's what each battery was evaluated on:
- Group size and terminal layout. A battery that doesn't bolt down safely is a hazard, not a bargain.
- Cold cranking amps against engine displacement. A 1.8L Forte doesn't need 900 CCA, but it shouldn't be under-fed either.
- Chemistry. Sealed AGM versus flooded lead-acid changes how the battery handles charge acceptance, vibration, and maintenance.
- Buyer-reported longevity patterns. We looked at when owners reported capacity fade, not just star averages.
- Warranty and serviceability. A widely stocked group size makes a warranty swap realistic.
We deliberately didn't test long-term durability beyond the reported 60-day window, and we didn't run controlled cold-chamber cranking tests. Those require equipment we don't have. Claims about sub-zero performance come from owner reports, not our own instrumentation.
One thing worth knowing: the CCA rating itself is defined under SAE International's J537 standard, which specifies the test temperature and discharge profile. When you see 760 CCA on a label, that's a standardized number, so cross-brand comparisons are fair. You can read more about how the organization handles automotive battery standards directly.
Buying guide — what actually matters for best battery for 2017 kia forte in 2027
Start with the label on your current battery, not with a brand name. Group size, terminal position, and hold-down style decide whether a battery physically works. Everything else is a tiebreaker after that.
What group size does a 2017 Kia Forte take?
A 2017 Kia Forte most commonly takes Group 48 (H6) or Group 24F depending on trim and engine, with Group 35 and Group 140R (H4) appearing on some variants. Don't trust a forum post over your own eyes: read the sticker on the battery in your car, then measure the tray length and width.
A tape measure settles it in about 60 seconds. If the tray is roughly 11 inches long, you're likely looking at a Group 48. Shorter trays point toward 24F, 35, or H4.
Does higher CCA actually matter for a Forte?
Cold cranking amps matter most below freezing, and a stock 2017 Forte four-cylinder is a relatively easy engine to spin. Somewhere in the 550 to 650 CCA range handles normal climates fine. If you see minus-10°F mornings, pushing toward 700 or 760 CCA buys real margin.
Going far above what the car needs doesn't hurt anything, but you're paying for capacity you won't use. Think of it as insurance, not performance.
Is AGM worth it over a flooded battery?
AGM (absorbed glass mat) batteries hold charge better under vibration, accept recharge faster on short drives, and never need water top-ups. That last point alone makes them appealing in a compact engine bay where checking cells is awkward.
The trade is cost. If your Forte is a simple commuter and you top it off with a maintainer in winter, a decent flooded battery will do the job. If the car does short trips, sits outside, or carries accessories, AGM earns its premium.
How long should a car battery last in a Forte?
Most owners report three to five years, with the shorter end showing up in hot climates. Heat degrades battery chemistry faster than cold does, which surprises people who assume winter is the enemy.
A battery that cranks slowly in 40°F weather but fine at 70°F is usually on its way out. Load testing gives you a real answer instead of a guess.
What about terminals, hold-downs, and venting?
Terminal position differs between group sizes, and a reverse-terminal battery can put the positive post where your cable won't reach. Check before you buy, not after. AGM batteries are sealed, so venting is less of a concern than with flooded units, but the hold-down bracket still has to clamp the case firmly.
If your battery is bouncing around, fix that before worrying about brand. Loose batteries fail early. For anyone who likes understanding how small mechanical faults escalate into bigger ones, our write-up on diagnosing appliance fault signals makes a useful parallel read: the symptom is rarely the cause.
Does the charging system need anything special?
A 2017-era Forte alternator typically regulates around 13.8V to 14.4V, which is compatible with both flooded and AGM batteries. AGM prefers a slightly higher absorption voltage to fully saturate, so very short trips can leave it at a partial state of charge over time.
A smart charger with an AGM setting solves that. It's a small purchase that extends battery life more than most people expect. If you want a sense of how we think about maintenance routines in general, our piece on routine household upkeep covers the same principle: small habits beat emergency repairs.
Frequently Asked Questions (FAQ)
Is the Weize Platinum Group 48 worth it for a daily-driver Forte?
Yes, for most owners. The 760 CCA rating gives meaningful cold-weather headroom, the Group 48 case is widely stocked, and the sealed AGM build removes maintenance chores. Where it stumbles is extreme sustained heat, where buyer reports note earlier capacity fade.
If you live in Arizona or Nevada, expect a shorter service life than a Minnesota owner would see.
How does the OPTIMA YELLOWTOP compare to the Weize Group 48?
They solve different problems. The YELLOWTOP is built for repeated deep discharge and recovery, which suits accessory-heavy builds. The Group 48 delivers more cold cranking amps and costs less.
For a stock commuter, the Weize is the better match. For a Forte with a big audio system or camping power draws, the OPTIMA justifies itself.
Will a Group 24F battery fit where a Group 48 was?
Usually not, and it's the wrong direction to try. Group 24F is a different footprint with reverse terminals, so cables and hold-downs may not line up. Measure your tray and match the existing group size.
If you're unsure, photograph the label on your current battery and compare it to the product listing's dimensions before ordering.
What's the warranty story on these batteries?
Warranty terms vary by seller and change over time, so check the current listing details rather than relying on older forum posts. What matters more practically is group size availability: a Group 48 or 35 can be replaced almost anywhere, while a less common size may mean waiting on shipping. Keep your purchase receipt, since most warranty claims require proof of purchase date.
Do I need to register or code a new battery in a 2017 Kia Forte?
No. Battery registration is a feature of newer vehicles with smart charging systems that track battery age and adapt charging profiles. A 2017 Forte doesn't require it, so a straightforward swap and a terminal check is all you need.
Do reset your clock and radio presets afterward, and let the car idle briefly so the ECU relearns idle trim.
Can I install it myself?
On a Forte, yes. Loosen the negative terminal first, then positive, unbolt the hold-down, lift the old battery out, and reverse the process with the new one. Clean any corrosion with a terminal brush before reconnecting.
Torque the terminals snugly but don't over-crank them, since lead posts strip easily.
Final verdict
For most 2017 Forte owners, the Weize Platinum AGM Group 48 is the pick that balances cranking power, availability, and price without asking you to overbuy. If you need abuse tolerance for accessories, the OPTIMA YELLOWTOP earns its premium tier. If your tray says 24F, the Weize 24F gets you there for less.
