Use all safety gear around battery acid.
I'd check to see if you have 2.5+ volts in each port of the battery.
1.Unscrew all filler caps on the battery.

2. Put the BLACK Neg cable of your VOM on the battery's Neg lug. Put the RED Pos cable of the VOM into the acid of the first hole. Should be 2.5 to 2.7 Volts DC. Yes, into the acid. You do not need to touch the lead plate inside.

3. Move the cables of the VOM up a hole and measure.... Rinse and repeat. Should be balanced at all holes.


I’ve been working with automotive batteries for 50 years. You haven’t a clue about what you are talking about.


50 years wasted

So you agree with his post? 2.5-2.7 volts per cell and you don’t touch the plates? Really?

I'm soooo sorry I got it 0.4 volts wrong. You are soooo right. You win the prize for the day. eyes

But just try doing the test and see if you get between 2.0 to 2.2 volts in each cell.

Not sure who PI$$ED in your Cornflakes this morning.
