Can I leave the batteries on the charger after it is done charging? or will that drain the battery
297025
I try not to leave them too long after they are done charging, but the times I have (a couple of days)there wasn't a problem. I wouldn't leave them in for weeks, though. I have read somewhere there is a very slight drain over time.

I leave them on the charger. I bought the batteries in a set that came with a charger and the charger I have auto shuts off once the charging is done. These type of batteries are also designed to not lose their charge over time as many other batteries do. So I would say that you can leave them in the charger.

It's OK to leave them in. I have the Nitecore quad charger and I find that the blue power on light is too bright when I'm at my desk so I unplug the charger and leave the batteries in. I charge both Nitecore Lithium and Eneloop AA & AAA. Goodbye Alkaline. (I use Panasonic D & C adapters.)

If the batteries are NiCads then it depends on the charger. If the charger senses when the batteries are fully charged and then ceases charging it will be okay to leave the batteries in the charger. If that is not the type of charger you have than do not leave the batteries in it after they are charged. NiCad batteries need to be exercized. So make sure they are run down almost completely before charging or they will develop a "charge memory" that will make them less efficient. If the batteries are Lithium than you may leave them in a charger or in the device they are used in. They do not lose their charge like NiCads and they do not develop a "charge memory". I hope this helps. If the batteries are NiCads then it depends on the charger.

There should be no harm, I have had no issues with leaving it on the charger after reaching 100% and have not heard of any problems. That said, I have but don't normally leave it on the charger for extended periods out of habit, not concern for the batteries condition.

I leave mine on the charger all the time. I believe its better for battery life to run the battery down before rechargingso don't be afraid to use it...

Yes, to a point. While no damage is done to the charger or batteries outright there will be over a period of time be a shortened life of the batter itself. As with any rechargeable power source it is best to deplete it as low as you can before recharging. Leaving it constantly plugged in means continuous heat which shortens the life span of the battery.

We leave our batteries on the chargers all the time they are not is use. So far, there have been no significant detrimental effects.

i believe the charger turns off automaticly after the battery is charged at least some do tho some chargers tell you that you are useing unnecesary electricity by leaving it on but i would suggest removeing the battery once it is charged.

Lithium batteries hold their charge for months. You do not need to leave it on the charger. This battery size will recharge within 15 minutes. The charger is smart, it will not attempt to continuously charge it when it does not need to. Leaving it on the charger will not hurt, but due to possible liability they tell you not to, since product failure with this much power potential can start a fire (very unlikely, but possible).

Make sure you remove the plastic strip between the batteries. They insert them to prevent the batteries from draining, but it will also prevent them from charging if you don't remove them.

Not sure you really don't want to let li-on batteries discharge completely. It kills their lifespan. It takes about 4-5 hours to charge from 10-15%

It might make the batteries not recharge quite as many times, but I do it all of the time and have had my batteries (Enloop) and the charger for more than a year. I do recommend that the charger be put in "soft charge" mode if you are going to leave the batteries in for more than 4-12 hours.

Either or, you can take them out of the charger, leave them in the charger, leave it plugged, etc. the charger shuts off to stop the batteries from over charging when the light turns green.

FYI, the charger stops charging after the battery is full so it won't burn out your battery!

Yes, you can. I've tested the charger while connected to a Watt's Up power analyzer, and once the batteries reach a near-full charge, the amperage the charger pulls in begins to lower. Once the batteries are fully charged, the power analyzer shows 0A of current flowing between the wall adapter and the charging base, meaning the batteries are no longer drawing a charge and thereof are not overcharging. You'll be fine leaving them plugged in, though I wouldn't keep them plugged in for days on end just because you don't need them to trickle charge and lithium batteries have a very slow self-discharge when being stored between uses.

I charge it after each use, leaving the battery on the charger when not in use.

No it will not drain its made to be left hooked up to your batterys, just plug in when you want to charge them

I have multiple batteries to recharge,so I keep rotating them. I never thought of any problem with keeping them in the charger.Once they're done,I take them out so I know they're OK to use
