How long should you charge it for? Will over charging kill the battery?

It charges in about an hour. Just watch the light; it lets you know when it has finished charging. I have accidently left batteries on a charger overnight without any damage but that shouldn't be done as a general practice.

One or two hours at most. The worst thing is to run them all the way down, then put on the charger and forget about them. If you will look on Amazon. Under some or the batteries, they give you the do's and don't of how to get the most life out of your batteries.

How old is the battery? Is it trying to turn over? 12 hours should be enough to charge up the battery.

I usually charge it overnight, then turn it the opposite way in the charger until I need to use it. These batteries hold a charge a very long time. Depending on how long I use it on a given day determines if I charge it that day or not. If I use it for just a couple of screws or drill o few holes, then I wont bother charging it that day. If I use it a lot in one day then I will usually charge it overnight and then the next day turn it backwards in the charger. I know it says they won't overcharge but you don't need to put an extra charge cycle on the battery if it's not necessary. I hope this helps.

Let it charge for 8 to 12 hours. It charges slowat first this helps the battery live longer. you want long term battery health let it charge 100 percent. Then it should be good. I love mine!

Just buy a smart charger so you don't ruin your battery, it will also prolong the battery life and charge it for the correct amount of tome

I haven't monitored to see exactly how long it takes to charge from dead to full charge, but I think 8-10 hours should be enough.

I did leave it charging for a long time and it died within weeks. So I am on my 2nd battery and put a timer on the power cord to charge it so I do not do that again.

You have to be careful not to have over charged the battery. If you did overcharged the battery by 30+ minutes the battery becomes useless or you'll notice a diffrence in power. If you know forsure that its not the battery then get yourself a circuit tester and start following your battery circuit flow, you may be able to narrow it down and hopefully find a quick fix.

I don't **think** its possible to overcharge it. I've had mine on and plugged in for a few weeks straight at least. I did have an issue where it wouldn't pair for awhile, but it was still powering on. I'm assuming the red light is only on when its plugged into the wall, right? Have you tried turning it on when it wasn't plugged into the wall?

I charged mine for about 4 hours before I used it. The battery loses juice as it sits. So only charge it before you use it.

I bought one to! It runs slow, need to charge after ever use. If you don't use for a day or so, the power goes down. You have to hold the on and off for 2 seconds. Some thing to remember, "Never over charge." It should take about 20 minute. But if you leave it over night! You'll burn the battery! I'd hope this can help. As I have had this problem on other products!

Unplug it, let it drain conpletely. The recharge it. Make sure it is charging and charge it no less than 6 hours. I found the battery lasts a long time but needs about 30% to power up. Charging for 3 hours wasn't wasn't enough. If it doesn't work ten sed it back . It needs a good but of power to start

Yes, charge it for a few hours. After that you are good to go for at least 2 full charges and a 3rd partial charge.

We usually charge it over night after each use to ensure a full charge for the next time. But after 6 to 8 hours it's good to go. I like to let them run it completely down and then charge it just so the battery doesn't get a memory.

Make sure you wait 15 minutes after using your battery before you charge it. If you charge it right after you use it they won't last long. You have to let them cool down.

I would recommend charging it for between 3-4 hours. There should be a blue indicator light on the side where the power button is that may turn off when its fully charged(if the device is already powered down)

There is no need to worry about charging time. Just insert the battery into the charging station and when the battery is fully charged the charging stops. There is no harm done by leaving the battery in the charging station indefinitely
