Battery Recharge Time using Generator

 

Hard question for you.

If I had

4 batteries - 6 volt, 225 AH at 20 Hour Rate (Trojan T-105) and the
batteries were 50% discharged,

 and I had a 55Amp Battery Charger with 13.6/14.2v direct current

running off a Guardian 7kW (6kw with natural gas) Generator -

approx how long would the generator need to run, using natural gas, to
recharge the batteries (assuming no other load from the generator or
from the batteries)???

ok, 4 batteries, in series parallel for a 550ah pack at 12vdc.

50% discharge means you need to add 225ah back in.

might take about 4 to 6 hours to fully charge the pack, or thereabouts.

This is the same question asked in another group and was answered with a very
comprehensive "depends" and each factor was described in fair detail.

The main point is that it will take longer than 6 hours if the top
voltage is 14.2V.
