Back to batterys

[Ralph L. Fullenwider]

To begin with, it would be helpful to know what Coach you have, FC?PT? year
and so forth. Do you still have the old boilers installed?
Batteries are like filters and should be changed as sets for optimum use.
When batts are tied together, the bank is only as good as the weakest one.
In fact, 2 new batts, 2 old, one of the old batts has a single bad cell.
The new bats will go to the level of the batt with the bad cell and in the
long run be hurt because of it.

These are deep cycle units and the plates inside, over time, will only take
so many discharge/charge cycles until the material holding the charge
deplete and fall from the plate to a space in the bottom of the
batt for that purpose. When this space fills, the lead sulphate will touch
and short, internally, the battery and die.

Remember the old batts will try to keep up with the new ones and actually
bring the new ones to the level of the old and the new ones will not regain
what has been lost.

Gassing takes place when the battery is at full charge state and the
charger does not sense to shut down and go to float voltage. And that is
what a smart charger like the Truecharge 40 does for you, it lengthens the
life of the batteries by being a 3 stage charger.
