New to the Forum. Hoping to get some answers here. Just bought an older JLG scissor lift 2658e3. Previous owner had just put in 4 new interstate batteries in it. He brought it on a trailer to my warehouse dropped it off and we hooked it up to a charger right away and the charger started charger it seemed as normal. He then left and I was monkeying around the shop for awhile and the battery % indicator stated that it was at 80% capacity, so I decided to just keep it plugged in and I left. That was almost three days ago. I went back to the shop this afternoon and I walked in and the battery indicated was still at 80% and the charger was still charging. Now, should I assume that the charger never shut off? Not sure how long it should take the new batteries to charge, I know it shouldn't take more than several hours. I took a multimeter to each battery right after I took it off the charger when it was still indicating 80% full and each battery read 6.9 volts. I drove it around a little bit and then remeasured the batteries and they were are 6.5 volts. Did a couple more things on the lift and before I left a couple hours later a remeasured one more time and they were at 6.3 volts. I should also mention that I had my wife go on the lift and run it while I measured the voltage and the batteries were measuring 5.7 volts while she was raising the platform.
So, long story longer, should I be looking at the charger or something else. I would have assumed that the batteries would have stayed topped off after being on the charger for 3 days and stayed at 100%. I didn't plug the lift back in before I left in fear that the charger is not working correctly and it wouldn't shut off after completing the charge and some how ruin the brand new batteries. I am not too savoy on these machines so I need some expert advice on where I should start looking for problems, if there are any. Thanks everyone.
