Trickle chargers/battery maintainers

SHALER · Feb 16, 2015

When you use these in the wintertime are you supposed to remove the battery water caps while on charge?

I have a friend that has 15+ cars/trucks that have one on each one, and does not.

I have 5 of them in use. No need to remove battery caps.

Only need to remove caps is to let vaporized water out of cell area caused by rapid charging and boiling of the solution. Trickle chargers and low amperage chargers don't do that.

Batteries already have a vent to allow gasses created inside during the charging and discharging processes to escape. So, as others have stated, there is no need to remove the caps.

Consider this- your vehicle is in normal operating mode(everything closed/covered up). You start it on a cold morning. The 100 amp alternator kicks in, putting out 50, 70? amps. That's quite a shock on the battery. It better be pretty well vented.

I think I have 10 of them plugged in here. Once a week I rotate them to something new. Things like the big diesel generator keep theirs full time.

Modern batteries are well vented, so no need to remove caps.

Remember that trickle chargers and maintainers are NOT the same thing. A trickle charger must be removed when the battery is full charged or it will slowly boil away the electrolyte.
A maintainer will do just that, maintain the battery at full charge without overcharging it.
