![ExpertPower 12v 33ah Rechargeable Deep Cycle Battery [EXP1233 ]](https://images-na.ssl-images-amazon.com/images/I/71dCIQe--nL._AC_UL160_SR160,160_.jpg)
This battery did not fit the battery box of my 12/2016 Model X, it was about 3/16" too wide and 1/8" too deep. The case that arrived was not the standard case as you see on the current pic, it was a smooth sided case which looked as though it was sanded down on a belt sander.
I contacted the company via their website, who responded quickly and suggested I put "soap" on the battery case, and blamed Tesla for their battery box size. Yes, Tesla should use a standard 12v battery configuration so we don't have to buy one from them every year or two, but the issue for aftermarket producers is to make a product that fits. Regardless, no amount of soap would have made this oversized case fit. The case would have had to be sanded down or banged in with a mallet. Of course I was not willing to do either operation because I would have probably nullified the ability to return the battery.
A second issue: I did connect the battery to the car's terminals, but the car would not power on. I checked the battery voltage and got 100mV. So in addition to not fitting, it was sent to me DOA. If I had shorted it somehow, I'd expect voltage to be Zero, from a blown internal fuse perhaps (if not a resettable one) - not 0.1V
After contacting them they did offer to come to my house and install it, as I live the next town over. That was nice but I need this car for commuting and the battery was so oversized they would not have gotten it to fit either. So I only saw a further waste of time dealing with this thing and I returned it.
