Trojan Batteries And Chargers

[orbitalsolutions]

Sounds good, Steve. I will talk to you further about the fill
system if I decide to go with the T-145's.

I'm confused about conventional lead-acid and the new AGM
batteries. I am trying to understand the practical differences in
charging time to bring a bank up from a 50% discharge.

Lifeline Co. has a 6V AGM that is a perfect repacement. At 6 volts
they are rated at 220AH. Four of these babies will give me a total
of 440AH @ 12V. I like the idea of a sealed power cell, but I have
lived with Trojans for many years. What I would like to know is if
there is a shorter charge time needed for AGM than the Trojans,
given a fixed charge rate of 110A 3 stage temperature sensitive
charge.

I think George Lowery might be able to help me(if that's possible).

George, in your new Apex I believe you have Lifeline AGM's. If so,
is the value of the battery bank 12V? What is the total AH rating
of the bank? At a 50% discharge, how long do you have to run your
genny to get a full charge? Lastly, How many amps are you charging
them with?

AGM's may be worth the price to me if they redeuce the charge time
compared to the Trojans. I hve been informed, by theory experts,
that the rate of charge of AGM types is unlimited, but I do not want
to spent 1500 dollars for chargers. I am going to replace the
originals with (2) 55A 3 stage temp sensing chargers.

That gives me a charging total of 110Amps. Will these chargers take
a 50% depleted AGM bank to full considerably faster than if they
were charging the Trojans?

Theory is just that. I am interested in practical application
results, and have no refrence points.

Still scratching my head and learning.
