Battery Question
 

Have noticed that after a charge cart runs fine up an incline, but after a couple of miles it will stall on a hill, have to get a running start to get up. I checked voltage on all batteries an hour after fully charged.

6.14;6.15;6.14;6.12;6.09;6.00 36.5

Batteries were made 11/07

Is it time for new ones?

Re: Battery Question
 

What voltage is charger putting out at end of charging cycle right before it shuts off? What does ammeter read at end of charging cycle?

Have you been exceptionally hard on these batteries? Run them down completely many times?

Re: Battery Question
 

The charger is putting out 41.7 volts.
The charger is reading 10 amps before it shuts off.
Dont know about battery abuse as I just recently acquired this cart.

Re: Battery Question
 

The voltage is a bit low at 41.7 and the amps are a bit high for end of cycle.

For comparison, I'm getting 45.8v at end of cycle at ~2A on a cart with a Total Charge charger (<--old).

Can you try another charger on the set and see if you can get a full charge on the set? It's not impossible to destroy a pack in less than a year but it seems unlikely. If the pack was completely drained every use you wouldn't get more than a 100 or so cycles out of the pack.

You can also try charging batteries individually or in pairs with a 6v or 12v charger and see how pack behaves.

Have you looked inside the batts for proper water levels?

Re: Battery Question
 

Yes water levels are good.
To charge individually do I need to disconnect batteries from pack?

Re: Battery Question
 

No. You can charge individually or in pairs while connected.
