I guess I'm wondering once it is charged, how long does it take to drain just sitting there. Would giving it a charge once a month be OK?

The battery is a 6 volt Infinity sealed lead-acid battery

and the charger is a universal floating charger that allows a fast medium and slow charge time at 6 or 12 volts. Once the battery is fully charged, it goes to a tickle and can be kept on charge for a long time without over-charging

I connect the battery to an old VistaLite 420 with a 10 watt bulb that I zip-tie to hang under my handlebar.



It worked very well on a very dark trail I used early in the morning this past winter. Now I'm using it on the streets. I don't really need the light so much but 2 different people at work drove by me while I was using the light and both said they were very impressed by how much light was coming out. They said I looked like I was riding a motorcycle.

I've always used a much smaller light on the road, using 2 re-chargeable C-cell NicCad batteries and every so often the batteries needed to be replaced because they wouldn't hold a charge. I was told this lead-acid battery would last much longer than the NicCad's but I always wondered if my lack of charging the NicCads over the summers contributed to their life spans.

I thought this would be a good place to ask some people who know about the topic. I appreciate any help I can get.

Thanks.
