I have also found that the Plews battery filler works well for most L16
batteries. One does need to be careful in recommending it because there
are some batteries that it fills higher than the recommended amount.
Also, be aware that this type of filler will continue to fill a bit
after the
The Plews Lubrimatic water fill jug (not a blue one) is a fine tool for
watering L16's. It is very accurate and the valve can be cleaned, I have
used them on hundreds off offgrid battery systems from Surrette, US
battery, Trojan, and Crown.
I am mostly using US battery because they get

Hey Guys you do have some great points.Here are my comments.
*Taking Readings while EQ'ing. *
Yes, this is not fun, and one of the big reasons I'm not a big fan of
EQ'ing at all. As a matter of fact, I tell people all the time if you
properly charge your battery bank on a regular basis,

Good morning everyone.
The reason you don't fill to full before you EQ is you want to prevent
water loss due to pressure.During the EQ process, there is lots of
gassing and pressure, part of the reason you should loosen the 1/4 bayonet
caps on the tops of the battery If the water level is

Looking at 30
years of batteries here and the Offgrid manufactures seem to change what
they like over time. Sometimes it is so complicated that I can't expect my

Probably preaching to the choir here and I’m sure not gonna argue with Surrette
But the purpose of equalization is to stir up the electrolyte so you have the
same strength from the top to the bottom

William,
It certainly is possible I've missed something, but I've never seen any
references to not eating batteries
Dave makes a good point; I also don't recommend opening the cells while
they are charging at a high rate. I like to get SG readings with the
electrolyte being mixed by bubbling, but I turn off the charging
sources, and let it settle down for a few minutes, before opening caps.
And I second
That does not sound best to me. I get the point but there are much better
ways. Not good for you to be close around a bank in EQ. If you are checking
water level every month the level should not be really low. You do this in
case you miss a cell a month back! You should be counting as the water
I think the instructions to "not add water before EQing" are just that
the fluid levels will rise as the batteries come to full charge, so you
don't want to end up with over filled cells. I would advise to just
fill all the cells to at least a 1/4 to 1/2" over the moss plates, but
to be a
Hi william
My experience shows me that first filling with water to normal full mark and
then eq provides the best results
Many years ago I had my own battery bank that needed an eq. Newer batteries
well maintained They were low on water but within the normal range. After 2
eq the sg were
My Rolls manual says:
"It is recommended to water the battery cells half way through the
equalization. This is to
assure the water is completely mixed into the electrolyte."

William,
It certainly is possible I've missed something, but I've never seen any
references to not eating batteries before equalizing. If anything, there is
statements saying make sure to check levels before equalizing. I'm not sure
why you wouldn't bring levels up before equalizing...

Friends:
Here is a conundrum I have often pondered. Maybe someone can solve this
for me:
Flooded cell O manuals instruct not to top off battery electrolyte levels
before equalizing. They also instruct to check SG before adding water.
Imagine two identical cells, one low on water, but
