Replacement Battery for Heinzmann 870-00-151-2030

[eyeree]

Last year I bought a custom trike chopper with a Heinzmann 870-00-151-2030 motor on the front wheel.

The battery pack lasts for only for about an hour with intermittent use and I expect it needs to be replaced.

I don't know anything about the history of the bike. I would guess it is at least 10 years old. I expect the battery pack is just as old.

At present it is difficult to get clear shots of the battery but I've attached some of the labels I can see. The control box (with the key switch) is external to the battery.

This is an "art" bike and is only used a week out of the year during a single event. The environment where the bike is used is very dusty and can be quite warm.

What would be a good replacement for this battery?

Also, what maintenance should I do on the motor?

Thanks,

Well Mike, It depends on how you want to mount the battery. the Baattery you have pictured is tiny by all standards. 36 volt 5 amp hour is usualy enough to get a bike a reliable 5 miles with no pedaling at full speed. More to much if you ride slower and pedal, but thats still painfully small.

If you have the room I would recomend mounting 3 12 volt 12 amp hour SLA batteries. Normaly, I'd recomend a lithium battery for long life and extended use, but since you use this bike just once a year, SLA is a cheap alternative and easily replaced.
