    • Does not fit 2017 Bolt EV
The dimensions are correct but the +/- terminals are on opposite sides. It also pops up that it will fit the 2017 Bolt EV, and this is unfortunately not the first time Amazon says something will fit one of our vehicles and it does not. Very disappointed with the return process and the experience as a whole, the return label provided "requires postage", so you are expected to pay the entire return shipping which for this weight and being a "hazardous item" is expensive, I had to file a claim with Amazon as the seller did not respond attempt to contact about this. This does not seem like a standard Group 140R as all of the 140R batteries I have looked up have the terminals on the opposite side. The seller needs to update their listing to clearly show the terminal orientation, the replacement I ordered and many other listings show this clearly. Unfortunately in looking closer at the negative reviews, there is a history of this, this could easily be avoided by the seller being more clear in the listing and Amazon failing in the sense that it clearly says it will fit my vehicle when it will not. 6-23-25 - After chatting with Amazon different times about this return and Amazon claiming they would refund the shipping as well, they have not. I have been a Prime member for years and have never had issues resolving any problems that were generally few and far between with Amazon orders. This has also resulted in lost trust with Amazon and leaves me questioning if continuing Prime membership is worth it and their "A-to-Z Guarantee" has been a complete failure in this case. ... show more

    • Do NOT BUY!!!
This battery said it was compatible with a 2021 Chevy Spark but the ports are not only backwards…the battery arrived damaged and a terminal eroded off. I tried to return it, they said if I paid for shipping, I paid for shipping and then it was rejected due to being damaged when I received it the same way I sent it back 😡😡😡 ... show more

    • The battery does not fit!!!?
The battery is not fitted my 2021 Prius, and when I tried to return it, the seller made it like yours fault the battery didn’t fit ( the negative and positive on the reverse). It says it will fit my car when I try to buy it.

    • Not as described
Did not fit even though stated “guaranteed to fit” with exact make/model of vehicle. Otherwise it would have been a great deal if it could be used
