Can a battery remain in the charger indefinitely without degradation of the battery? I'd like to have a charged battery on hand at all times.

This is from the charge cradles product description "if you leave a worn-down battery in for four to 10 hours, the charger conditions the battery with a tune-up mode, and at completion, it automatically converts to trickle charge, so you'll never damage a battery by leaving it in the charger too long."My guess is you can. I would consider it if I used it frequently

I am not sure. My friends with Dewalt tools brag that their tools remain charged for months. Recharging takes less than one half hour.

It depends on the battery type. Ni-Cd batteries will develop "memory" so if you leave it on the charger all the time between small uses and not full uses, it will eventually ruin your battery. NiMH and Li-Ion batteries don't suffer from this effect. http://www.all-battery.com/batterytechnicals.aspxhttp://www.ebay.com/gds/What-is-the-difference-between-NiCad-NiMH-and-Lithium-/10000000002033731/g.html

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.

I have had a DeWalt drill and drill-driver for years. I have three batteries and I always keep one in the charger. All of the batteries are still in excellent shape; it has never hurt any of them to stay in the charger until needed. A quick swap and you're ready to go. These DeWalt chargers are designed to work this way and they will not hurt the battery.

In many other devices, (razors, phones, etc.), it is generally recommended not to leave a battery on charge at all times, however since I have two batteries and chargers, I have no experience with leaving a spare battery in a charger at all times. I always check the charge status of a battery before starting a project and find at least one battery ready to go. The chargers are very quick in recharging a battery if it is required.

Any batter will degrade over time, however, this kit comes with two batteries. They charge in exactly one hour. I charged both of my new batteries to full charge starting at 8:12 PM and ending at 10:12 PM. You can leave one in the charger, and the other in the drill. You'll always have a charged battery.

First of all you didn't mention if your battery is an nicd battery or lithium .if it is nicd do not leave it on the charger more than 30 hard.they will develop a memory that shortens the. Life between charges .The full charge method and discharge is important for the nicd battery.But if it is a lithium ion battery it's OK to leave it on the charge .anywaylithium batteries begin loosing their storage capacity from the moment they are manufactured and it can range from5% to 40% each year no matter what you charge it all the time or not.

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 had issues with my battery because I kept it charged when not in use. I found out you should NOT keep it charged; rather keep it in the vac until it dies and then recharge, this will extend the life of the battery. I bought a new battery and that solved my problem. Good luck.

I plop this in the charger without regard for battery cycle but since I don't have two of these to run a side by side life test I couldn't answer your question directly. However, I've had this for over a year now and it seems to be standing up fine with erratic/inconsistent use of the charger.

I know if you leave it plugged in all the time it can end up ruining the battery. But if that is not the case then I would contact the manufacturer.

I always kept mine fully charge and in my purse for backup. The batteries will be fine, I used mine for a year like this until I got a new phone. The batteries are still in great condition. The true worry comes from leaving them on the charger to long it cause the battery to get hot and expand which makes them go bad much faster.

I keep it charging regularly, but I myself have yet to drain the battery completely

I leave mine on the charger all the time with no problem. But then, I use these batteries everyday.

I believe the battery charger has an overcharge limit which allows the battery to charge to its fullest no matter how long the battery sits in the charger. I leave my battery in the charger for about two days and have not noticed any problems. Hope this helps.

We leave them on a little while longer without noticing any harm - and nothing in the packaging of any charger I've had suggests you have to get the batteries off immediately. I wouldn't store my batteries there :) But all that happens is the light for the charged battery goes solid and the others continue charging if needed.

I refresh at every charge. All it does is drain the battery all the way before it charges. And that is the best way to make batteries last. But there's nothing wrong with just charging up if you need them quickly

Yes it will still remain active while charging. Actually it's best to keep it on the charger while using cause if you don't the battery only last about an hour & and half or 2 hours.

I would NOT leave this on a charger. I believe that battery is meant to be run, up and down to maintain it's ability to accept a charge. Leaving it plugged in is not what it is meant to do.

Newer models have a voltage regulator so they can be left plugged in constantly, but older models didn't have that and could be damaged if left on too long, so you may get mixed messages about this. This is from the description here on Amazon: "The onboard battery automatically stops charging when it has reached a full charge--allowing you to keep the JNC660 connected to an AC outlet indefinitely without causing any harm to the battery." What I've done to insure I'm not leaving a few batteries I have "drained' but am also not leaving them plugged in 24/7 is set a timer on a charger to come on for 15 minutes a day, otherwise I "manual charge" them right after using them.

I never thought about this. I keep my batteries charging all the time. I haven't noticed a problem. Yet, that is. Christine S may have a good suggestion.

Store your batteries fully charged. Also, try to avoid letting lithium ion batteries (like the ones in cell phones) discharge completely after the initial 4-5 cycle "break in" period.. Repeatedly draining them all the way can shorten battery life. Most battery chargers have a protection circuit built in so leaving a battery in the charger past the time it is fully charged will not harm it.

Yes you can. The charger is designed to recognize a full charge and then will trickle charge so that the batteries stay charged and ready but not overcharged. I am doing the same on mine
