Customer Reviews
It fit,and it started the motorcycle.
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.
