Battery Charger Overcharge?

[Chuck Wheeler]

There is a maximum charge rate that you do not want to exceed if you want to
preserve the life of your batteries. If you have four deep cycle batteries
6 volt batteries this would be between 10% and 13% of the battery's rated
20-hour capacity. In the case of a FC with four 6 volt batteries (T105)
this would be around 40 amps. ANY well regulated charger will charge around
this rate no matter what its maximum output is. The extra capacity will
allow for the operation of other devices while the batteries are being
charged. On our coach since we do not use inverters this need is met with a
60 amp charger and meets our average demand.

Unless you are going to exclusively use a RV park and shore power you
do not want to use a 40 amp charger in a Bluebird. Again your
choices should be driven by your individual family requirements. If
you dry camp at all then you want to recharge your batteries quickly
and efficiently. Even the FC models have at least 4 six volt deep
cycle batteries or 450AH of battery power. If you use the 50% rule to
discharge them to before recharging it would take a truecharge
40 approximately 5.5 hours to recharge the batteries. With a
refurbished Xantrex Freedome 458 inverter/charger that furnishes 100
amps charging and 2000 watts of inverter power it would take
approximately 2.25 hours to recharge. Price of the truecharge about
$450
