can I leave it on the charger

I am looking at the operator's manual for this light. It states "charge the unit before first use using the 120V AC charger for 2 hours or until the battery status LED lights green." "The battery status LED lights red when the unit needs charging." It further states "When using the 12 VOLT DC charger,DO NOT CHARGE FOR LONGER THAN 2 HOURS." So it appears you could leave it on the charger when using the AC charger, but not when using the DC charger. If you buy this light, I am confident you will like it. They have a similar model now that is supposed to be waterproof, but I would stick with the SL5 as the new waterproof model appears to have a problem with the switch. Good luck!

Yes you can leave it on the charger. My father leaves his on the charger and only takes it off when he needs to use it.

I have for over a.month an cant tell any difference in it i have 3 of these lights

Yes. Running them for a couple of months with no problems. Have 6 of them used on a golf course. I only charge my personal one weekly.

Just charge it up and take it off the charger. They last a really long time. My nephew used his up to three or four months after taking it off the charger. He drives a semi and that is why we got one because they were so bright and we were amazed.

Yes you may. It seems will stop charging after fully charged.I have left the plug in for over 24 hours couple time, and everything is still in working order

I believe you can, but don't know why you would want to, I've never had it drop the charge while not being used. Battery life is exceptional.

I leave mine on the charger overnight and sometimes longer and have had no problems.

According to the instructions, it is ok to leave the battery in the charger after the battery has reached full charge. It has been my experience with DeWalt products that no harm has been done if you don't remove the battery from the charger until you ready to use it.

Oh yeah..I would leave my charger at home...it only charges the phone when you press the button on the back of the case

not sure. I don't think you need to keep it on the charger. I can try and let you know if you ask me in a week.

My understanding is that has to be charged on the charger and I have never tried, but I ma sure you will need to use the charger.

I would not advice leaving it for more than a few hours after fully charged just me due to trickle charging is still on. I rather be safe than sorry.

You can but it will charge faster if you turn it off. Nice back up battery. I would recommend it.

No, you cannot. But keep in mind, that the case they come in keeps the unit clean and free of dust and is highly visible. If you put it on your desk or dreeser, you won't forget to put it in its charger. Keep in mind, the charge will hold its power for 16 hours, so it's more than enough to get you through your day.

Holding a charge depends on how much you use it. Yes you can leave it on charger for long periods, it shuts off when fully charged.

No, it can only be powered on with the rotary knob. That said, I don't see why you couldn't leave it powered on and connected to a USB charger.

You can charge it with the case on. I charge it every night with the case still on. There is an open space on the bottom.

As far as I know it is left on the charger until needed. Perhaps we both should write to the mag light people and ask them this question.

No you can't leave it in the charger indefinitely and as far as I am aware there is NO drill charger anywhere that allows that. Even the fancier Li-Ion chargers that shut off, won't keep the Li-Ion battery topped off. However, since Li-Ion self discharges much slower, it would seem to be the better battery chemistry to suit your needs.

You can leave batteries in the charger. I try not to make a habit of it because I'm not sure how it affects the life of the batteries. If you leave them in, at least you can be assured they will be ready for use.

Yes. It will run off the charger (any mini USB charger or PC) while left on. Don't leave it off with the charger attached.

I do not. I did not want to run the risk of any possible damage to the battery or charger. The battery holds its charge, so there is no need.

Nope! Pop it in, leave it in, and you can still charge your phone with a wall charger like normal whenever you want.
