what is the battery chemistry is it the new NMC or the earlier one

Don't know about the chemistry, but the battery on my vacuum died after about 7 months of use (with a 6 month warranty, of course), and the local repair places said that they can't get parts from Dyson to replace the battery. Very very disappointing. It's now a dust collector externally instead of a dust collector internally :-(

The battery is made of Nickel, Manganese, Cobalt/Li-ion. It is the earlier one. The DC59 has the new battery.

I've never used the old battery, but from what I can gather the housing is different. It's quite sturdy and very well made. It does last quite some time but I've not actually tested the complete burn time. Hope this helps, I intend to buy another so that should be a good indication.

I don't think I can help you. I bought it to replace the one in the solar light in my shed. I'll be damned if I am going out in -30C to verify the size difference of the terminals. I believe the original battery is on a shelf in the shed. Sorry. I hope someone else can help you.

I agree that the photo is of the old battery, but the part number agrees with the RedLithium number on the Milwaukeetool.com site. I agree with Alex. I am suspicious because of the photo, and because the price is almost the same as the standard M12 battery.And there IS a difference in technology with Red Lithium over the older version.

I'm not a techie, but understanding from years ago is that most batteries once had chemical electrolyte, until the air battery was developed; when both were available, the "a" designated the battery was an air-cell. Sorry, forgot to clarify: both batteries worked in the same applications, but 312a was an air cell, 312 was chemical electrolyte. Both worked as 312's.

I'll agree with the consensus.I cannot confirm or deny compatibility with the very old NiCd batteries, and in fact do not recommend it, but I can confirm by experience that NiMH - both "standard" and "long shelf life/pre-charged" - and the iGo batteries both work in this charger.

I assume "regular" batteries refers to 1.5v alkaline batteries. Using a battery tester and a high-end volt meter I've concluded that each recharge results in a bit less energy than was true of the original "new" charge. How long a battery "lasts" depends on what you are using it for and how much the appliance you are powering is used. Assuming the same appliance/use, you will need to recharge sooner each time. This is also true of 1.2v rechargable batteries (Ni-Cad and NiMH), but their chemistry allows for recharges closer to the previous one and many, many more recharge cycles. I figure 4 alkaline recharges is about all I trust. After that the chance of equipment-damaging leakage is greater and a recharge may get you 50% or less than the original 1.5v capacity. NiCad and NiMH rechargable batteries can go hundreds of recharge cycles.

Yes Jim it is the new version,the old version had a different battery that doesn't fit the new version.

according to their website, here is the Testing capability (battery list): 1.2v NiMH / NiCd rechargeable [AA, AAA, C, D] 1.5v alkaline [AA, AAA, C, D, N] 3v cylindrical lithium [CR123, CR2] 3.6v Li-Ion rechargeable [18500, 17650, 18650, RCR123A] 9v alkaline & carbon zinc This can all be found on their website here: http://www.ztsinc.com/minimbt.html

The difference is the model number. If you have an old battery, check the model number on the bottom of the battery.

I was just given the PowerShot A560 (haven't had time to play with it, yet). Anyway, excuse my ignorance but what are NiMH cells and how are they different from alkaline?Thanks for your assistance.

I found a good comparison on Ehow that describes the differences and advantages of ech http://www.ehow.com/about_5605853_silver-oxide-vs_-alkaline-battery.html

You have nothing to worry about with the current, improved version. I talked directly with ThermoWorks about this and learned that they have upgraded the unit's circuitry and are now using a better battery. I have had mine for nearly two years, use it regularly, and have not had to replace the battery yet.

New models with slightly less power. There both in the website catalogue - for now. You can compare specs. The new model has the advantage of having fresher batteries.

yes, the new one is 6 cell (I believe the old one was a 3 cell li-ion) - still working great.

Short answer, yes. Long answer is NI-MH is a newer type of battery make up that can hold power longer than the older Ni-cd batteries.
