BikeMaster Lithium-Ion Battery DLFP51913 for BMW R1100RT 1993-2000 has Remarkably low self-discharge for extended storage periods.

Keeping your motorcycle in a bike garage can be tough. And if you have one of those cool, enclosed, roller-style garages it can be nearly impossible.

The temperature can fluctuate widely from the searing heat of summer to the bitter cold of winter. If your battery is fully charged, then it will discharge quickly in the hot summer months and may not even get cold enough to charge up enough in the winter months.

So for cold winters and hot summers, you need a battery that can perform well under these conditions and deliver power to your bike when you need it the most; without being effected by extensive temperature ranges.

6.FirePower Fire Power Battery W/ACID Compatible With BMW R1100RT 1994-2001

BMW motorcycle owners should check out the FirePower FP-FROSS2. It can be hard to trip the bike over, but if you do, it is likely that your battery will be flattened. Even more so if you leave it sitting for a long time.

Expansion and contraction of the cells are things that happen in every battery every day and eventually, that will cause the battery to fail you. Even batteries with acid inside them will lose their charge slowly.

They take on a different form, becoming damp on the bottom or side or in a number of places in between. This is where keeping your battery at a constant charge comes into play. When it is at full power, there is no loss of power because it doesn’t use.

10.BikeMaster Conventional Battery 51913 for BMW R1100RT 1993-2000

My BMW motorcycle battery died and I found this battery on Amazon.com for $109.00 with free shipping. After using the battery for a several weeks I started to notice it would die if I left my lights on for more than half an hour while sitting in my garage.

I product-tested this battery for you and here’s what happened: Within a few days of installing the new battery (rechargeable) – that came with the acid pack – the bike wouldn’t start due to the acid turning into liquid and leaking out.
