Customer Reviews
Just purchased a couple of these batteries for older RT1150s that had the same battery. The old ones lasted around 5 years
I've ordered a few batteries from you guys over the years. you usually have what I want at a good price. Thanks so much!
BMW K1200LT battery
I recently purchased a “maintenance free” battery from Battery Mart for my 1997 BMW R 1100 RT. Despite living in Texas I had the battery shipped to Michigan in which I was enroute to. The battery arrived within 3 days, the day upon my arrival. I installed the battery that day and have been using the bike daily for the last two weeks. Very satisfied with price, delivery and performance.
Battery Marts service is excellent. I bought this as a budget batter for a RA850R. It hasn’t disappointed.
Great service, prices, fast shipping!
Ordered prior this purchase and will order again.
Easy search tools that connected me to the options for my Bimmer. Picked one, got it fast and was up a riding with hardly any down time.
I’ll be back!
