Key Fob Replacement Batteries (Pack of 2)
Don’t forget the small battery that starts your day. This two-pack keeps your key fob working so you can get in and drive.
These batteries are made for a wide range of Cadillac models, including the XT5. They provide a fresh, full charge to ensure a strong signal. You’ll get a reliable range from your key fob.
Having a two-pack is smart. You can replace the battery in both your main fob and the spare. It’s cheap insurance against a dead fob at the worst time.
Pros:
👍 Fits many Cadillac models
👍 Two batteries in one pack
👍 Fresh charge for full power
👍 Easy to find and buy
👍 Very low cost
Cons:
👎 Must check fitment for your year
👎 Not a car starting battery
👎 Generic brand packaging
My Honest Opinion:
These are a no-brainer to keep in your glove box. For a few dollars, you avoid the panic of a dead key fob. Just make sure the battery type matches your specific fob before you buy.
Mighty Max Battery YTZ7S
This is a small AGM battery for motorcycles and other powersports. It is not the correct battery for your Cadillac XT5.
The YTZ7S only has 130 cold cranking amps. Your XT5 needs a battery with at least 600 CCA to start reliably. Using this battery would leave you stranded.
It’s a good battery for its intended use, like a dirt bike or ATV. The sealed lead acid design is maintenance-free. But please do not buy this for your car.
Pros:
👍 Good for small vehicles
👍 Sealed, maintenance-free AGM
👍 Lightweight and compact
👍 Fair price for its class
👍 Reliable for the right application
Cons:
👎 NOT for a Cadillac XT5
👎 Far too weak to start a car
👎 Wrong physical size and terminals
My Honest Opinion:
I’m including this to warn you. It pops up in searches, but it is the wrong battery for your XT5. It won’t work and could damage your car’s electrical system. Stick to Group 94R batteries.
Key Fob Batteries for Cadillac (2006-2023)
