Edd,
I made a few videos regarding the charging and discharging properties of
lead acid batteries. Some of them ran a little long, sorry.
Properties of Lead Acid Batteries #1 - Surface charge -

Properties of Lead Acid Batteries #2 - Discharge Amp-Hours -
Some good answers so far. I used to sell and install those things and
they ALL have issues.
We'll start with basic principles. You can get a meter that keeps track
of current in and current out. Kind of like an odometer that rolls
forwards and backwards.
The current out part is only

Hi Edd,
The battery voltage is only an indication of the state of charge of a lead-acid battery when the battery has been without load (or charge) for several hours. Otherwise, the voltage is pretty much meaningless. Many devices measure the
Thx all - very helpful. I had a battery issue on the 1st. This thread is
timely.

Edd,
As I recall you are still on a mooring right? You're using the motor and
solar to keep the batteries "charged"? If so then it is unlikely that you
are ever really getting all the way 100% charged.
As others have mentioned the only good way to use voltage as a measure of
the state of
Not sure what youre asking but no way did the power drain frim the dources
you report should cause a problem. Dont make new problems we got enough
with these great older C boats

Last year, I installed a Blue Sea battery monitor and I’m a little perplexed
about the readings I am seeing.
Last night, before an amazing fireworks display at Hempstead Harbor (thanks to
fellow Lister Neal Gallagher for the guest mooring), I looked at the display.
