Brand new batteries, only 37.1 volts
Hi gang,
I have a 1998 DCS cart. Brand new Crown 235 batteries. Put them on charge over night and after 12 hours the voltage read 37.1 I found a similar thread where JohnnieB told the guy to jumper the relay on the control board. I started to do that, but since my charger was a powerwise and not a powerwiseII, I thought I better check before I let the smoke out of the electrical components and they don't work without smoke...... Attached is a pic of the control board with the relay circled. Thanks! |

Re: Brand new batteries, only 37.1 volts
Is it possible the charger timed out, before reaching full charge?

Re: Brand new batteries, only 37.1 volts
Not sure, so should I put them back on charge?

Those wires carry around 10A at 120VAC, so the jumper wire needs to be at least 16Ga. ------- However, before you you do that: Does the transformer hum? If it does, the relay is closing and there is no need to jumper it. Also, if the ammeter is showing an amp reading, the relay is working. ------------ New batteries can take a lot more than 12 hours to charge and we don't know what the pack voltage was before putting it on charge, but 37.1 is mighty low for being on charge for 12 hours, so something is wrong and it needs to be fixed before the new batteries are damaged. Was the charger working on the old set of batteries? |

The ammeter was up around 20 when I first put it on charge. The old batteries never got out of the 36.? range. I just got the cart and they were 8 years old. |

Re: Brand new batteries, only 37.1 volts
Plugged it back in.
Amp meter went to 20 amps, but within 5 seconds it had worked it's way down to 5 amps. Measured voltage for about 1-2 minutes. Went from 44.0 to 44.3 Thanks again for the help. |

Re: Brand new batteries, only 37.1 volts
Sounds like the charger is working.
It should shut off automatically around 45V, but it will probably take hours to get there from 44V. The proof is when you measure the pack voltage about 12 hours after the charger shuts off. It should be at least 38.2V, and most likely higher since they are new batteries. Be sure to break them in properly. Here is how: http://www.cartsunlimited.net/Batter...n_Methods.html |

Re: Brand new batteries, only 37.1 volts
It will take several charge cycles for your new batteries to reach a 100% SOC. Don't be alarmed and follow the procedure in the link "JohnnieB" gave you.
