Battery frequent fill!

mway

Having to add water about every other day to batterys. Can see liquid around the caps.They all check good voltage wise, just having to top off about every other day. Possible that charger overcharging. Any way to test the charger with multifunction meter? Thanks for any help or advise.

Are the batteries filled to the caps or just 1/4 inch above the plates as recommended?
Take a voltage reading of the pack as near the end of the charge as you can. Post that highest reading here.
Are the batteries old?
Are you charging in a very hot place?
See question #1.

Batterys filled to 1/4 " above plates. , 3 years old, charging overnight inside garage where temps are in upper 80s.Pack 51.1 each battery individually 8.3-8.5. What else?

If you see much water on top, you are overfilling the batteries. You should fill them AFTER charging and never before. The level rises during charging. Only add water before charging if the plates are exposed and then only to cover them.

If they are filled to the caps, what's the best way to remove some of it, or should I? Maybe a turkey baster to suck it out? Wearing proper safety gear of course. :)

Only fill after charging and that is when the water is below the plates the water is on top of the battery.The batterys are NOT being overfilled. Any way to check the charger for overcharging?( my original question)

This is what you need to do for your original question Then we can answer you. Need to find out what volts the charger turns off at. Should be around 55 to 60 volts

It is normal for the charger to gas the batteries during a full charge. My experience is that as batteries age, they gas more and require more frequent fillings.

Funny story- I used a turkey baster to remove battery water once. Seemed like a pretty clean method until my pants came back from the laundry with 1000 pin drop holes. Seems I was spraying or splashing a little upon emptying the baster(d)

roygpa1713, never remove any water because you are also removing acid. Let the excess water gas out.
