Hi,I found out the reason whi my battery was not getting charged.I removed the cap strip on top the battery and noticed the plates where not covered by the fluid at all.A little fluid was still inside.I properly filled the battery with the acid pack but I guess the amount wasn't enough.Evaporated perhaps???.Anyway....I added some more acid and covered the plates.Let's see if that was the problem or is to late.

Hmm ... I used to have a VW Beetle that was chewing up batteries. The battery would turn up dry every two or three days, and I'd fill it up. Ended up being the voltage regulator was bad, was allowing the battery to overcharge, which was boiling off the water.
Might want to check/change the rectifier.

The voltage regulator is ok.With the motor running at 4k I get 14.5 and 13 at 2k.I beat the acid pack they gave you is not enough to cover the battery plates.Silly me I did not check that when I filled the battery.Live and learn

Don't you have to use distilled water in those types of batteries along with the acid?

The label says not to add anything...but I use distilled water and it works ok. The acid itself does not evaporate....the water in it does.
Also our batteries die because...sulfites build up on the lead plates..so they do not charge...bear with me now...I am a retired combat medic...not a chemistry major....but this does work....pop the top on your battery....dump it...no you are not losing acid..just water....acid is embedded in the lead plates...locked in by sulfite deposits..boil 2 cups of distilled water and stir in 4 table spoons of magnesium sulfate..(Epson salt) to dissolve it... and refill your battery with it..... charge your battery at 2 amps or higher for about 8 hours....As it bubbles the build up on the plates is broken down and removed .. Then discharge the battery ...using a bulb or electric motor..... Trickle charge the battery over night and it is ready to use. I have done this on 3 'dead' batteries and voltage on all of them shows 13.6 to 13.8 volts.
p.s. Do this outside...the gas bubbles are explosive Hydrogen gas..

I don't deal with batteries you have to maintenance yourself but this is great to know Thanks carasdad! |
