lower absorption charge for gel (14.1v for gel versus 14.7 for wet cell and AGM in 12v systems).

The charge Voltage and the max amps pushed into the battery are different animals .

AS long as the voltage is at least one volt higher the battery will charge , the question is how long it will take , and that is usually determined by the Amperage provided

That is why a 135A or larger truck Alt with smart regulator gets the job done in lowest time.

For 24V systems 250 to 300A alts can be had from bus parts shops.
