How do I charge lead-acid batteries? Answered
I have two 6-volt ~4.5 AH batteries, and I'm not sure how to charge them. I know that overcharging and voltage regulation can be an issue. They have markings on the outside that say "standby voltage ( voltage)", "intermettent use voltage (voltage)", and I was wondering what voltage I use to charge them, how I know when they're fully charged, etc. Advice is welcome. Thanks!
