I use a deep-discharge battery for power for a light and a fan in the event
of an A/C power failure. It looks like a car battery. Anyhow, after years
of service, with a small charger, I've started having problems with charger
to battery contact. The charger uses the usual claw-type clamp-on
connecter. I've tried using one of those sleeve-with-a-wire-brush-inside
cleaners to rotate on the battery terminals. Doesn't help for long. Every
few days the charger light goes goes from green to red and I have to fiddle
with the connections to the battery to resume trinkle-charging.

Any suggestions on something to keep the connection working? Any way to
clean the charger clamp on maybe? File it?

Small problem but annoying.

TIA


Just guesses here but my first thoughts are bad charger, dirty
terminals, outlet going bad or battery going bad.
