Trojan Batteries And Chargers

[orbitalsolutions]

Thanks, Don. The cheapest price I've found on the T-105's is $69.
Sounds like about $30 dollars more per battery.

I'm just starting to figure out how to upgrade my DC system from the
original configuration. It's not easy for me to get a grasp on the
performance of the practical application.

I mean to say, if the bank is 50% depleted, with the T-145's you
would need to replace 260 AH to get a full charge. If you had the
AGM replacements that cost $209 a piece, you would have to replace
220AH for a full charge.

Being that the final 10% charge takes forever(scientific term) in a
practical application you would only charge them up to about 85% -
90%.

The big advantage of AGM types, besides no acid or filling required,
is that they supposedly will accept a charge must faster than the
conventional lead-acid battterys.

So what I want to know is this...

Given that I have (2) 55Amp 3 stage temperture sensing chargers.
How long(amount of generator running time) would be required to
bring both the above mentioned banks to an 85% - 90% charge?

Thanks in advance, I actually remember Ohm's law if that will help
anyone.
