How long will it hold a charge while not in use?

All Dewalt batteries should be left in there chargers pluged in when not In use. They will have a longer life. Dewalt designed the chargers to maintain and replenish a charge only when the battery needs it. I have many Dewalt tools and have talked directly to Dewalt about this . Hope this was helpful.

It will hold a charge for several months, but of course the longer it sits and self discharges, the lower the remaining charge will be. For practical purposes it's still a good idea to put some charge in it before use if the work will require more than a few moments of use, but you won't be almost required to do that every time it sits more than a couple weeks like you would have to with NiCd packs.

i haven't experienced any noticeable drop in charge in an extended period of time. also ive labeled both batteries 1&2 so that after use i can remember which one to charge

Definitely months. I bought mine Sept 2014. I never used it. Never charged the batteries. Then needed it Mar 2015 - 6 months later - and it worked! This was without ever charging it. So whatever charge the batteries came with lasted 6 months. So I can definitely say the charge lasts for months.

the responder Paul must be a dewalt employeegive me a breakyou say the battery should always stay in the charger but dewalt sells the damn thing with only one slot for a battery in their charger. so we are supposed to take care of this like we did with our babies?

I have had mine for more than 30 days and it still has a charge... That's with only a charge when I got it .

No, it can only be used while unplugged, but it holds a charge for a good hour.

I haven't exactly timed how long the battery lasts, but depending on how much I use it, I generally need to charge it every day. Naturally I turn it off when I'm not using it, but I would say once a day with normal use.

Typically with lots of use it generally lasts 1-2 hours depending on use and takes approximately 3 hours for the battery to charge up to full capacity again. I hope this helps with your decision.

I've only charged mine once and forgot about it for a couple weeks, I just used it yesterday to type this review and it appeared to be nowhere near empty so I'd say it holds it's charge very well. Back when I used it more frequently I could go two days on a single 4 hour charge.

so far mine has lasted 6 hours without needing a charge. I haven't run mine down yet so I cant say for sure but 6 hours as of now

Cannot truly say, I was using it 5 - 8 hours daily and it still had battery. If I had to be over night without a charger turn it off and start the next day, it still ran but limited.

It lasts for about 20+ minutes, but I don't use it for long except for short sessions. Please note, it's best when the battery is allowed to drained and then recharged to prevent memory effect. Most folks set it back in the charger which is the worse thing you can do.

You can go quite awhile once charged...I think at least a month if not more. You did remind me to check mine though since it has been awhile since I charged it! ;)I've never kept it plugged in though...only plugged in overnight to charge it up and it holds a charge for a good duration of time!

If the battery is fully charged, it should last for about 6 hours. This is a rough guess based on my using it for about a week, a short time each day, before needing to recharge the battery.

I'm not quite sue--I've never used it long enough to drain a charge. My guess would be several hours. Sorry I can't be more helpful.

Battery life is fair. It depends on usage. 3-4 hours can be used when it fuly charged.

The owner's manual states that leaving it on charge is not a safety concern, but it can shorten the battery life. They recommend not leaving it on charge for extended periods, 30 days, if it is not used. If you are using it regularly there should be no problem leaving it on charge.

not very long at all..I only charged it about 2 hours and it was ready to go.

I've had mine a while. I usually keep it in my purse for emergencies. The longest I think I've kept it without using it was about 2 weeks and it was still charged, so I'm sure it can last longer (I just haven't had to test it for more than that).

Not that long! If it's only working when plugged in, something is wrong. It also holds a charge for quite sometime. I can't remember the last time I charged mine (though I only use it sporadically).
