3 questions. Perhaps I missed it but, (1). What is the chemestry, NiCD or NiMH? (2). What is current rating? (3). If they are NiMH is it safe to charge with simple charger meant for NiCD without dammaging cells?

The chemistry is Ni-MH. AA2.4V/MSM-plug 2000mAh. Not sure if you can use with NiCD charger. Instructions state to use with specified charger. May have to ask the seller about charger compatibility.

Karl, Sorry I didn't notice your question eariler. Any 'value-charger' (such as this Duracell CEF14, Rayovac Easy charger, Sony BCG34HLD, etc) can be used to 'prime' a completely drained NiMH or NiCd cell. Just put it in the cheap charger for 1-2 minutes, and that should be enough for the BC-9009 to recognize it again. If the cheap charger requires charging in pairs, you can pair an empty cell with a full cell - as long as you don't forget and leave them in there for too long. If your question is: "Can I use a NiMH charger to recharge NiCd cells"? The answer is yes - if you know what you're doing. - Dumb timer-based charger expects the cell capacity of a typical NiMH to be higher (around 2500mAh). So if you put in a low-capacity NiCd cell and leave it overnight, the cell will be badly over-charged. This is not going to cause any danger, but it is bad for battery lifespan. If you can remember to remove the cells after a few hours, then it is still alright. - Smart charger like the Sony BCG34HLD looks for a voltage 'dip' (negative dV/dt) to terminate charging. The -dV/dt for NiMH is smaller than that for NiCd, which means any smart charger designed for NiMH can also handle NiCd, but not the other way around. I recommend the Sony value charger, because it is the only one that can recharge individual cells. Sony Cycle Energy BCG34HLD4KN Power Charger with 4 Pre-Charged 2000 mAh AA Batteries

The charger has a warning printed warning on it saying "Caution: Charge only NiMH or Rechargeable Alkaline batteries by iGo Green. Other types of batteries may burst causing personal injury and damage." It's interesting that those different types of common rechargeables are listed as compatible, so it might be possible to use the charger universally, but it comes down to the voltage and current limiting details of the iGo charger, that it might not be an exact match for other brands like Eneloop so a battery could overheat while charging. The Eneloop charger lists charging voltage at 1.2v, iGo lists output at 1.6v. If you want to charge Eneloop, most NiMH - NiCd chargers do work fine from my experience, because both those battery types only output at 1.2v. iGo is featuring rechargeable Alkaline with a cell voltage of 1.5v.

To tell the truth, it depends upon the charger that you are using. If you are using the one that came with battery and simply slides onto the battery, it has no way of knowing when the battery is charged and will keep pumping current into the batter, unless you disconnect it, and will eventually "fry" the battery. Doesn't matter if it is NiCad or NiMh.Do yourself a favor and buy the "Black & Decker FSMVC 9.6-Volt to 18-Volt Slide Style Battery Charger". It regulates the charge and won't fry the battery. I've been using two of them for over a year and have not fried NiMh batteries, so far! To tell the truth, it depends upon the charger that you are using.

The charger is capable of testing sub-C size NiMH or NiCd cells however they do not fit the C&D; adapters. You would need to add a spacer in the adapter on the negative terminal of the cell in order to physically fit and be able to charge and test sub-C cells. If you have some loose change two nickles or three pennies happen to be about the right thickness. Of course that is beyond the scope of the manual that ships with the charger, use at your own risk. But that would allow you to test the sub-C cells for capacity and determine their state of health.

I will never purchase this charger ever again, if you read the 1 stars in reviews theirs just like mine and had basically the same problems. I ended up buying a B6AC 80watt 6amp charger for about the same price and have used it constantly for 2 years now with out a problem. But the answer to your question they both will charge NiMh,NiCd,LiPo,LiOn batteries.

I have two B&D; 18v changers. One is clearly marked for both NiMh and NiCad the other is marked only for NiCad batteries. If you look at the black label below the red charge state light, you may see NiMh/NiCD for chargers that are intended for use with both types of battery. Older B&D; chargers may work just fine with NiMh batteries but it is also possible that that my under or over charge the battery and shorten its life.

See answer from Alex - he is correct. New charger charges NiCad and Lithium Ion. Old NiCad only compatible with NiCad.

NiMH and NiCd are the battery chemistry, the only difference is that NiMH batteries have a higher energy density (higher capacity from same sized cell) Any NiCd charger will charge will charge NiMH.

One is based on NiMH and the other is Lithium-ion. I've used the NiMH and I'm not at all happy with the welding/mechanical connection on the negative side of the battery. Both are Low Self Discharge (LSD) which is good. I'd go for it and get the LiON 9v @600mAh -- In theory it should last 3x longer. These NiMH 9v are "claimed to be LSD" but I get poor shelf life, nothing like the Sanyo 'White Label AA" which are fantastic NiHM LSD batteries. I've had superior results with Lithium-ion, but you pay the price. You will have to run your own tests and real world applications. I'd buy the set with the 4 batteries and the recharger (as they are only asking a bit over $2 for the charger -- some batteries can be touchy with what charger is charging them. Would enjoy seeing your feedback on your experience.

Are these batteries similar to Ni-MH or lithium batteries? I need Ni-MH or lithium. The item description only says the charger will charge Ni-MH, it doesn't say if the ones includes are Ni-MH.

I have charged AA and AAA in any combination. However, I usually charge them separately because of different charge rates and amp/hr settings. I usually try to balance the batteries for no perticular reason. For instance, I put two "AA" into the left bay and two in the right bay. I find that the charger will charge them to the same voltage. BTW, I always use my volt meter to make sure that the batteries measures above 1.2 volts. If they are less that 1.2 volts, the charger will not charge them. This is a characteristic any new chargers for NIMHs.

Yes, the BT-C2000 will fully charge NiMH or NiCd cells up to 20,000 mAh capacity. The best charger is subjective and depends on individual requirements. I believe at this time the C2000 is the only charger that can test C and D cells for actual capacity.

Possibly the best way of answering this is to quote from the leaflet that comes with the NiMH battery: "The new NiMH battery is a true "drop-in" solution. It will work with ANY and EVERY Mag Charger flashlight and charger, regardless of when they were made."I have three Mag Chargers, one is a recent model which came with a NiMH battery and two older (ex NiCd) ones, which I have recently upgraded with NiMH batteries and they all work fine on both the old and new chargers.And before anyone makes the obvious comment, yes, I probably have some sort of flashlight fetish - probably stemming from a childhood fear of the dark!

I just use regular batts and avoid all the fuss. Ni-MH batts will can't hold their charge very long at room temperature as well as alkaline varieties, are pretty pricey compared to alkaline, and eventually will die out too (or reach a point where their half-life makes their use totally inefficient). Flip runs quite well on normal AA and I never have to worry about overheating/charging or any issues many of the 1-star folks bring up.

I have heard of people doing it with any charger, but it is dangerous and can easily cause a fire!! If you want to do it, do it outside in a safe place. You have to jolt it back to life with the NiMh or NiCd charge first, you have to get it above the dreaded 3amps. I have never done it but have friends who have, and yes they have burst one or two into flames!! I have also heard of them changing polarity, but have never seen that happen. I would highly recommend getting a laser temp gun to monitor the battery wile trying to get it back to 3amps. But like I said, THIS IS DANGEROUS AND IT IS BEST NOT TO TRY IT!!

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.
