Replacement battery for my portable jump box, (JNC-770R) I've had and used for years. The original battery is failing quickly so ordered a replacement but not going to arrive as earlier predicated:
They say another should arrive by Tuesday. No harm, nor foul with me although this gets used often.
Placed a small load test onto the original battery which is 12VDC, 22ah rated. With a fresh charge and using simple mathematical conversion to reserve capacity, a 25A load should run consistently just over 52 minutes before the battery decays through 10.5VDC which is considered discharged. This one made just about 4.5 minutes before being discharged so seen better days.
