Long Term Battery Charging: When NiMH AA batteries are not in use can they be left in the charger indefinitely?

to N Lee The Engineer: You wrote 'keep them in the charger', but: - a 2012-Jul-28 review of the charger wrote 'Let them die completely ... every time!' - a 2010-Sep-12 article wrote: 'make sure that the battery is fully spent before you even begin charging it again' (from 'Tips on Laptop Computer Battery Care', By Suzie Sanchez; the Web address can't be posted here) (such article is expressly about laptop computer batteries, but might apply to other types of batteries). Is your view supported by any written support on the Web? Thanks in advance.

I get long life with fully charged NiMh rechargeable AA batteries. But, NiMh batteries lose at lot of their charge when sitting idle for a few weeks, so I carry a set of lithium batteries as a "backup". The lithium batteries can stay "fresh" for ten years or so, ideal for an "emergency" set of batteries. I know a lot of folks who only take 200 or 300 photos per year. That sort of person could get a year (or MORE) of use from one set of lithium batteries on the Fujifilm S700, without the "hassle" of carrying a charger on their trips.

According to the manual, "If the green indicator light is 'ON', the charger is plugged in but the battery pack is not inserted, or the battery pack is fully charged and is being trickle charged." Since these are Lithium-ion batteries, my experience is that they hold a charge very well so keeping one in the charger isn't necessary. Ni-Cad batteries do not hold a charge as long.

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.

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.

It works fine with NiMH batteries. Just charged my NiMH today. Not sure where is was written, I use this charger with a NiMH battery, it works fine.

The best way to get the most from your NiCad batteries, is to not leave in on the charger. Recharge only when the batteries are exhausted. They will last for years that way.

The primary problem is that NiMH batteries do not like to be force-fed/overcharged, andthat is exactly what NiCd "low-end" chargers do: they are basically constant-current"trickle" chargers (low current, takes many hours to charge, then keep feeding thissame charging current even after the NiCd is fully charged). NiCd batteries just shrugoff this excess charging current, but it will eventually "cook" your NiMHs.That said, NiMH will pack much more punch into given size...so if you don't leave it onconstant charge (drain it, charge it overnight, then unplug it once "properly" charged)it should work quite well.Of course if you ditch the crappy little wallwart "charger" and hook it up to a properNiMH charger, it'll work Great!

AmazonBasics NiMH batteries should be stored in charged state. That is the whole point of using low-self-discharge batteries: charge them in advance, so they are ready whenever you need them.Ordinary NiMH cells should also be stored in charged state, but in this case the higher self-discharge rate will deplete them in a few months. If you store NiMH cells in depleted state for a few months, their capacities will drop the next time you charge them. That's why you need to run REFRESH (Discharge/Charge) operation on them multiple times, in order to recover the lost capacity.

With NiMH batteries, you sometimes need to entirely drain them to get them to take a full useful charge.The discharge button does that (and then once done, charges them all the way up).

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.

I'm not sure. The longest I've left the flashlight on the charger is overnight. It's not good for any battery to be charged constantly.

In our application we have had batteries in the charger for a year and a half, with no ill effect, so far. We have 3 batteries and rotate them thru the charger. Yes, no problem leaving them in the charger

This is typically hard to gauge since you can put either regular alkaline batteries or rechargeable batteries I currently have rechargeable batteries in since they last the longest of any non rechargeables, I am using Sanyo batteries and their charger, they typically last me about three months that is if I don't use them on high drain things like games and with games about two months

my understanding is any NiMH battery inserted is brought slowly to full charge, and then either stops charging or provides a slow trickle only if needed. I do not leave my batteries in the charger wasting current, and the newer model batteries hold their charge for a long time anyway. In any case this is supposed to maximally protect your NiMH batteries. I use new Eneloop batteries by Sanyo. Suggest you go to sony website to review and see the writeup on this charging unit. It seems to be nicely designed, except the top comes off easily, but not a problem.

I use rechargeable NiMH batteries. A set of fully charged NiMH batteries lasts more than 3 months but I don't use the screwdriver everyday. There are days when I use the screwdriver for more than 4 hours and some days when I don't use it at all.
