I am trying to setup a battery charger for Sealed Lead Acid battery's, and am curious about how to go about it. I'm hoping someone can point me in a direction of some good reference documents on the internet, I havn't been able to find any of them.
Also, I have a trickle charger that is designed for a Seal Lead Acid battery, but it's designed for a 12V 7AH battery, will this charger work for my 4 AH sealed lead acid battery? I would assume that the charger measures simply by voltage, therefore it would charge any size seald lead acid battery, but I wanted someone else's thoughts on it before I go charging stuff that's not designed for it. Even if this charger would work, I am still needing to build my own circuit for charging one.
