Customer Reviews
Brand new. Fit right into the battery compartment with no problems. Was chardge and ready to go when it arrived. The price was right. So affordable compared to the oem battery. Seems durable with strong connections. Registered to the car problem also.
This is the one you want. Don't try to 'save a little more' by getting 'about the same thing' because you need it yesterday. You'll just end up spending as much (and twice the time) as the dealer. Ask me how I know...
Price was a bit high but made in the USA and is the exact reaplcement for BMW i3's 12v battery. It even has a hole for the vent tube.
