I use a deep-discharge battery for power for a light and a fan in the event

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

Could it be that the charger goes to red when the battery is fully charged and only shows green when it's being charged? I have some rechargeable lanterns that act that way, the indicator goes to red when fully charged.
