charging batteries

i was just reading another thread & the advice was to charge batteries seperately. a friend who is a ford mechanic had told me it does not matter. why would the batteries need to charged seperately? i've recently charged them at he same time. what damage might i have done?

Re: charging batteries

None what so ever... I charge mine together all the time. 12 volts is 12volts

If you have a bad cable or something like that and your batteries aren't provide equal amounts of power to the starter motor, then you'll have one that is lower than the other. Charging them together with an automatic charger probably won't allow the lower battery to fully charge.

I disagree completely... Volts are volts and amps are amps. The condition of the cable dosent have anything to do with charging or discharging the batteries. Loose connections may cause and issue but it dosent matter if its #4 or 18ga its still 12v.

If your really concerned about the cable between the batts it runs right on top of the core support...

Some automatic chargers won't charge both batteries effectively if one is "flatter" than the other.

I charge mine together all the time.

They're in parallel, so if you charge one, the other is being charged also.

I charge them together, but a "bad" battery will inevetably Sak the other, so that is why seperatly is said, but if they both test fine charge together

i should have been more clear. my question should have read is it ok to charge both batteries at he same time. i put a trickle charger on each battery. it still sounds like it is ok to do so.
