Title: how long can an SLA be shelved without damage?
Post by: dr.ph0b on July 25, 2005, 10:13:21 AM: since they lose power over time just sitting there, and a deep discharge will damage an SLA, whats the shelf life of a fully charged 6v and 12V SLA?

I have a very old SLA close to 7 years old and it still works like a champ.

If you don't have a charger that will do that, buy one and leave your battery attached to it all the time when not in the field.
