can you leave the battery in the charger once its fully charged and charger still on
823267
Yes, but I take it out as the battery does not lose power if not in charger.
823268
Have not done that. I personally do not leave batteries in chargers once charged. A basic fear of fire.

You're not supposed to leave it on the charger if it's plugged in. It will lose the battery life sooner. Only charge for four hours when needed.

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.

Yes is the easy answer, But... If you research general information on Lithium-Ion Batteries you will learn that Full Charge is not ideal for storage. So, if you can, take them out of the charger.

Yes. The charger is a smart charger. When the battery is fully charged, it goes into a hibernation mode and will maintain the battery, without overcharging it.

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.

Yes you can but not advised. It will go down to a trickle charge when batteries are fully charged. ok

Do you leave your battery on the charger when it's fully charged ? If yes its probably won't keep a charge and needs to be replaced .

You can, this charger will maintain the battery and never overcharge or destroys the battery

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.
840522
Yes the charger shuts off when the battery is fully charged but will come back on when the charge goes down.

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.

I would say yes. This charger allows you to leave the batteries on the charger so they have a full charge when you put them in.

Oh.. If you are asking if the charger will shut off after the battery has been charged the answer is yes but it is recommended that you do not leave the battery connected to the charger all the time.

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.

You should never leave a battery in a charger unattended. There is always a slim chance of a battery or charger going bad, violently.

I cannot answer your question because I haven't tried it before. But according to the manual, it says when the battery is fully charged, the charger will change to trickle charging. Since the electric tooth brush which I am using now also uses trickling charging, and I leave it on the charger whenever I am not using it. I literally leave the electric tooth brush on the charger almost permanently. You may base on this to decide whether you can leave the batteries on the charger for a week or two.
