New batteries

[kybird]

On my 1986 pt40 with the v8 Detroit. The 6 12 volt batteries where just not holding up. So I went and got 6 6 volt batteries. Got them wired in + to - which would make 3 large 12 volt batteries then ran them like 3 12 volt batteries to the bird. Also found out my charger was not working up to speed. So I got the charger from the garage and set it on 10 amps. How long should it take to bring the batteries up to full charge? Also shouldn't they have been full charged when I got them from the battery shop? They will not start the bird. It just clicks like a low battery. Checked and cleaned all cables also.thanks for any help

Based upon the state of charge the new batteries were in when you purchased them, charging at 10 amps could take 2-3 days.


No, they normally are not fully charged when you purchase them unless the store had them on a float charger at all times.


Give them time before trying to start the engine again.


The bad charger in the coach may have been why the 12 volt batteries were no working correctly.

They are still on charge. I will let them still there. Looking at new chargers. Amazon seems to have a 100 amp to float charger that has good reviews.

Rodney, I replaced my charger on my 88 with a new smart charger. It charged much better and wasn't that expensive. I can't remember which model but something like this.

At 10A, if they are really that discharged, it's going to be a few days! I'm actually surprised that 6 of them are that dead they don't even turn the engine over.

Here's a good charger

I am running this charger and it works great, seems pretty efficient. It's 60 amps, but for my needs that's perfect, I only have 4 GC2's.

It just clicks. I will try this evening after work. If not raining here.

Amazon has a a power max pam 4 stage smart charger 100amp with a 4 star rating. For 165.00

Just make sure your circuit can handle the amp draw . The 80 amp charger calls for a 20 amp circuit .

We are buying one of these :

I almost bought a Powermax, but decided to try the USA guys first. The 100amp will use about 14 amps at 120vac balls out, but that should be a rare occurance. I think a 15a circuit will be fine 99% of the time with these chargers.

maybe you could disconnecting batts from coach and check there state of charge and charge them one at a time... you may have a problem in starting circuit it happens...
