 |
|
I posted a question awhile back in regard to charging 2 batteries at the same time. I didn't understand the answer so the question must not have been properly worded. I have a 2 battery (same size)system and I want to charge both batteries at the same time with my "battery Tender Charger" The negatives are already both connected to ground . can I connect the positive terminals together to the positive of the Battery Tender, thus charging both at the same time. I don't understand why there would be a problem, But???

Sorry Jim . . . the article I referenced was
intended to show that batteries of any size
and condition can be charged and/or discharged
in parallel. Each battery will accept and hold
what ever energy it's chemistry condition will
allow. Each battery will deliver what ever
energy it contains even if a small fraction
of its paralleled brothers. Except for what is
now an exceedingly rare shorted cell (12v battery
becomes 10v battery) two paralleled batteries
do no exchange significant quantities of energy.
The short answer is, yes. Just parallel those
puppies and hook up the Battery Tender. I've had
as many of four lead-acid batteries being
shepherded by one maintainer with great success.
