New batteries never reach full charge

[Esteban_Escobar]

I bought an old, beat up 1993 EZGO Marathon as a project cart. After repairing the frame and replacing the wheels, the next step was new batteries. I bought a MODZ Max36 15 amp battery charger and 6 new batteries. I installed the batteries and plugged in the charger this morning, and after 7 hours the yellow light was still blinking. For those of you unfamiliar with the MODZ charger, a blinking yellow light means the battery is above 80% but not fully charged. Once the batteries are fully charged the blinking yellow light changes to a solid green light.

I called the store where I bought the batteries and they confirmed that the batteries were at 95% charge when I bought them.

So why, after 7 hours on the charger, is it not showing fully charged?

Man I bought one of those from Amazon and the same thing happened. The Modz charges at a 15 amp trickle. After 20 hours I never got a green light. You need to return that thing and get a Lester Summit ll charger@22-25 amps. Just sayin'.

Also, any place that says "these new batteries fresh off the pallet are at 95%" is a crock. They never show up on the new pallet at 95%. Maybe 80% at best. They're "blowing smoke up your a**" to save face. And, I'm also not sold on those modz chargers either, just another "Johnny-come-lately" box with a fancy looking label. (From the big rock candy mountain, if you know where that place is).

Thanks. I submitted a return request thru Golf Cart King and they sent me a prepaid label within the hour. I'll be sending the MODZ charger back and buying the Lester Summit II.

Seen two MODZ chargers come in with carts a customer purchased online brand new...BOTH were the issue. Not a fan...

And it can take up to 12 hours to charge your new batteries. Did you check your new battery pack volts before you put them on the charger?

I second that. Regardless of the charger - rely on the voltage, not the time. Keep in mind that many O.E. chargers also run in the 15 to 18 amp range, so that is not a problem in itself.
