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.

A smart charger typically has a low trickle-charge current after charging is done. Ordinary NiMH cells typically self-discharge at about 1% per day. Some even faster than that. So it is a good idea to keep them in the charger, to make sure that they are still fully charged by the time you need them.With low-self-discharge (Pre-Charged) NiMH cells, this is not necessary. In fact, continuous trickle charging will probably reduce the battery lifespan in the long run. If the batteries are stored for a long time, just recharge them (using a smart charger) once every 6 month or so.

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

This charger CAN recharge NiMH batteries as well as the included Alkaline batteries.I wouldn't try standard disposable alkalines, but I use it for my sizable collection of NiMHs as well - in fact, I bought it to replace a failed charger that blew up four of my newer NiMH batteries.

Usually Energizer chargers can only charge Energizer batteries I would make sure it says compatible with high capacity NiMH batteries even if it can charge them it could take a longer time & it may heat the batteries to an unsafe temperature

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.

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 am sorry, but I do not know the answer to this question. I normally put them on the charger and put other batteries in the unit the batteries were removed from. I put the discharged batteries in my charger, two or four at a time, plug it in and go about my activities. When they are charged the charger light turns off and I remove the charged batteries when I notice they are charged. Usually it will be the next morning or in the evening. It is not uncommon for batteries to be in the charger for eight to 12 hours. Tom Kerr

These batteries can be charged with any charger that charges NiMh batteries. It should say that on the charger's package. When charged, you just use these batteries like any other batteries, based on the size. For example, the "D" cell batteries can be used on any appliance that takes "D" cell batteries.

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).

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.

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 Dakota (and Oregon) models do NOT provide for recharging batteries while in the unit. A DC power supply may provide supplementary power while you're in your vehicle possibly extending internal battery power somewhat, but I get 6-12 hours pers use on one set of fully charged NiMH. Personally, I carry a spare pair of charged AA's AND a pair of alkalines just in case.

I have the standard charger, but I do not know if it will work for NiMH batteries...good question. Perhaps you should contact Black & Decker, and see if they have your answer.

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.

We bought 2 pairs of NiMH rechargeable AA batteries, along with a charger. You can play almost 2 rounds on a charge. NiMH last longer than NiCad.

The Charger should utilize a trickle charge feature that essentially reduces the amount of charging once the batteries are "Full". So yes, you can leave the batteries plugged in while in storage as I will be doing the same.

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.
