I have several SLA 12 volt batteries that have gone dead from lack of charging and simply sitting on the shelf. I've been considering keeping them on a string with a 13.8 volt DC source but don't want to "Charge" them. Merely want to keep them topped off. What would be a good amperage to maintain them? I'm thinking 20 mA to 200 mA. Advice please? Or redirect my thinking if you have a better solution.
These batteries just sit on the shelf waiting for a project or a use. If they're not charged every so often, which I often forget to do, they go dead. Need help stopping the bleeding (of voltage).
Thanks.
