First, this is a great battery. Some said it improved their sound system and it actually does! I have a very early build 2018 M3, payed extra for the enhanced sound system. This battery made a big difference in quality sound that was already there. The You Tube video is easy to follow, no install worries at all. After having my car for 3 years and 6 months it was a matter of when the OEM battery was going to give up. And would probably be at the worst time in the winter. The only downside is the $500 price tag. If that’s what it takes to make this battery at a fair price so they can make a decent profit, I’m good. If you can afford the car, you can afford not to “cheap out”. I like the 4 year No question not prorated warranty a lot! Let’s hope I never need it.
Bought this battery for my Model 3 because I got a fault from the factory one. Freaked me the heck out because creating an appointment in my area to get anything on my car fixed is a nightmare. Tesbros and this battery helped eased my worries by showing me how to install the battery with their install video, backed by their warranty. This battery is much lighter than the factory one and I noticed improvements in my speakers after making the switch which was a huge plus for me. Anyone having problems with their 12v battery I highly recommend this battery and Tesbros.
