Best AA rechargables.

I just realised I was misreading the units on the axis in reply to Andy.

If I'm looking the same graph as you (originally I was looking at the table at the top with the almost invisible decimal point) I just read the 9.4 minutes from the legend.

I don't think I would have recognised what the M stood for, even if I wasn't skimming right past that data.

So far, impressed with some Lidl Cs and AAs. Best of the wide range of rechargeables I have are Contour AAs. These:

They do variations on the theme - it's the ready to use 2100mAh ones that I have, as per the link

NiCd as opposed to NiMh can probably cope with the high current, but won't last very long of course (as in will need recharging).

Bit more investigation showed the motor has a shorted turn or two on some of the armature windings. Very different resistance readings as it is edged round.

So basically scrap. Nothing to do with the batteries. ;-)

Now you know what you want for Xmas.

Wish they still made the identical one. It was just so right for me. The ones on the market these days are bigger - especially in diameter so not so nice to use.

Other good thing was returning it to its stand put it on charge. No need to fiddle with a plug or remove the battery pack. And a press to run switch you could use with the same hand as you hold it in - no silly 'safety' locks.

What did you decide in the end about new cells for your Ryobi?
