How long does it take to charge usually. Mine has charged from 12.8 V to 13.6 V in almost 6 hours...

Mine was charged for approximately 6 hours and a month later has held the charge.

I charged it for 24 hours, also keep it on the charger after each use as it's used daily at my shop to jump off cars.

Your in luck as I happen to work for Stanley Black and Decker. If you started at 12.8VDC you already had a partial charge. 6 hours to top off the battery is a reasonable expectation. For a fully discharged unit (~12.2V) charging a minimum of 12 hours is recommended. This unit uses polymer lithium cells that dump their energy extrememly fast. Its the only reason this thing works at all. It is meant to assist a weak battery not jump a dead one!

It takes very little time to charge, maybe an hour. I can definitely say not more than 2. I haven't timed it yet. I just know it's pretty quickly. It certainly charges faster than my old rechargeable batteries LOL

Depends on how much is left in the battery. I just let it charge overnight, I have never timed the charge, but I would assume at least 4 hours from a full discharge.

I charged it overnight. Don't know how long it takes for it to start working.

It takes about 12- 16 hours to charge. You know it's charged when the red light turns green.

I've had mine for just about a year... I'm noticing just a bit of drain on the battery life. I'd say it's a strong 10-15 minutes. That's about all you should expect out of 6V. At less than half the price of a 12V I still recommend it. If they had one with a crevice attachment and at this price I'd buy stock.

It takes about 30 minutes to charge. It will usually stay charges for around four hours.

I got a similar unit recently and when I plugged it in, it too showed 100% charged. However, I unplugged the charger and checked the battery voltage which instantly dropped to under 6V. So that told me that the battery wasn't accepting a charge and the "100%" reading was coming from the charger just while plugged in. So I left it plugged in and after an hour it did start accepting a charge and the reading dropped to 60% or such. So it does take at least 12 hours, after that if it starts displaying 100% it probably is charged.

Not sure. I let it charge over night but am not sure if it takes that long to really charge it. Sorry

I have used it for 6 hours, and it still had a charge. Don't know average, I charge it after use.

It does take a good amount of time to charge because it has such a high capacity. How long have you been letting it charge for?

Really I don't know. I usually charge it around 8 hours and after that, I use it. But I don't like at all.

Mine came with at least a half charge. I plugged it in until the light turned green and then a couple more hours just to make sure. I'd say it takes about 6 hours to go from completely drained to completely charged.

In my experience it depends on how far it has been discharged. The times I have needed to fully charge it, it usually takes about 2-3 hours.

I charged mine for 12 hours the first time and mine worked perfectly. You might want to make sure the battery connection is good.

I normally charge it overnight, but if I had to guess, it's about 3-5 hours. However, the length of it being able to charge other things far surpasses three hours.
