It's a Weize brand battery, which had a recent discussion thread here: https://slickdeals.net/f/17226829-weize-platinum-agm-bci-group-47-12v-60ah-h5-size-47-automotive-battery-109-25-more-free-s-h

I just want to add the comment that it's wasteful to replace your battery as preventative maintenance. I recommend keeping a jump box in your car. When your battery appears to act up then you can give yourself a jump and go get it tested. Especially if you have a prius or EV that only uses the battery to run the ECU at start up vs turning a starter. If you're replacing your battery in 4 years when it could be replaced in 1 to 5 more years (yes I just bought a prius with a 12 year old yellow top battery that gave me the last 2 months of it's life before it quit) then that means you're paying 20 to 50% more for your batteries instead of getting their full worth out of them. That is not a slick deal. Plus having the jump pack you can give other people jumps with less hassle than hooking up jumper cables to your car. Plus you have a backup jump start system in your own car and that will save you time and hassle of waiting for a jump.

Disagree... Preventative maintenance is best. If you have an aftermarket flooded lead/acid battery and have 4 or 5 years on it, less if you are in a super hot or cold climate, consider replacing BEFORE you end up in a situation. Make sure to recycle your old one.

Weak batteries can sometimes damage critical systems (ECM, TCM, FICM, IDM)
And your alternator has to work hard to keep charging it back up...

And here is the funny part. I have a car that the battery lives in the trunk/hatch. 12 years on the OEM battery before I detected any weakness and replaced. Six years so far on the replacement, No issues at all with all cells in perfect condition. With this car, it's not a critical car with lot's of sitting, so it's kind of a game for me. Crazy how simply moving batteries to the trunk/climate controlled space could do more for the environmental movement than anything.

I think a good the compromise here is to regularly use a battery tester so you know when it's time to replace your battery. Just blindly changing a battery can be very wasteful. Some batteries simply last much longer depending on the car and conditions.

When my Prius 12v battery gave up the ghost I replaced it with a home assembledlithium iron phosphate battery that I pieced together using $10 used headway cells in a 4s configuration with a 100a bms. I used it for about 3 years before I sold the car. Worked fine never gave me any problems. I also tested the battery on several EV's in place of their 12v lead acid batteries, like a older model 3, a Fiat 500e and a Kia Niro EV and it worked fine in all of them.

Assembling a battery like that might not be someone's cup of tea but it is an option and potentially a very long lasting one that you could rebuild if u ever needed to. It's also possible to buy an already assembled lithium iron phosphate battery to replace your 12v lead starter battery as well but those batteries can be expensive!

For my Prius I never saw the car pull more than about 30amps from the battery at any given time and that was for just a few seconds. I did try starting a v6 ICE with the battery I made and it could do it but it struggled, I think the bms allowed a maxed out 250a for a few seconds. I also tested the battery of a few different size outboards up to 50hp 4 stroke and it started and ran all of them no problem!

For some cars they already install them somewhere inside the car (buick enclave has it underneath back passenger seat for example) and it should make some difference for ones that aren't inside engine bay because temperature swings shouldn't be as extreme (during winter from cold to hot once engine warms up or from ambient to very hot during summer heat). I think main reason they don't do it is due to more wires and placement in such area where it's easily maintainable while not taking up precious storage/usable space.

Actually the main reason why they don't do is because standard lead acid batteries are not sealed and will release acid into the environment. You see this all the time when all the crusty acid residue starts covering the positive battery post. You REALLY don't want acidic vapors permeating your car interior.

I'm sure the Buick Enclave takes a lot of steps to ensure this doesn't happen - maybe they have that compartment sealed off and/or maybe they come with a sealed, AGM style battery straight from the factory. Many manufacturers won't want to do this because it increases costs AND it will likely make ignorant customers cross when they try to replace a car battery and the auto parts store tells them that they MUST buy the most expensive AGM battery rather than the cheapest thing on the shelf.

I ended up ordering one of these because the battery in our Surbaru Forester went bad. It wasn't even that old, but I think I accidentally let the charge drop too low one too many times during a cold snap and it just always has trouble cranking in the winter. It will work just fine for a few start ups, then start getting weaker and weaker until it barely cranks. I'll charge it up using a NOCO 2amp and it'll be good again for a few days until the cycle repeats itself.

It was very well packaged and seemed decently well made. Size 47 wasn't too physically different from size 35 so minimal modifications were needed. Came fully charged and car cranked right up after installing it. At $105 shipped this is a crazy deal for an AGM battery, time will tell how well it will really perform.
