AA 2700 mah battery charger

[blaze_away]

I've have 2 dozen 2700 mah Rechargeable batteries which don't seem to charge fuly in the charger I currently use.

Anyone know of a decent charger, preferably one that'll do 8 or 12 at a time and fully charge them.

ours does 4 at once.
only a comet jobby. never had a prob with chargeing.

I find my 2700mAh batteries take about 24 hours or so to charge properly in a regular charger, so I've ordered a couple of one hour (4 cell) fast chargers (£24/pair, delivered). I'm sure there are lots of reasons not to use these, but I've got as many batteries as you and only 2 4-battery chargers so it's a fulltime operation keeping them chargered.

They're sitting at the post office awaiting pickup so I'll know on Monday if they are any good.....

I'd suggest some Sanyo Eneloops with either the Technoline 700 charger

http://www.batterylogic.co.uk/technoline/technoline-i-charger.asp

or a Powerex MAHA charger/analyser.

What either of these two do is to slowly discharge then charge and repair any capacity loss (as far as it's capable), but poor quality batteries will be highly variable in mAh rating..

Yup. I bought one of these after a similar experience with a Uniross charger that took several goes to get a full charge. Takes a while to power a heavily discharged set of Eneloops, but worth the wait. Had a bit of a 'mare finding one in the UK a while back. Not sure if that's any easier now.

+1 for PowerEx - you can buy the charger here

A lot of the chargers simply use a timer system to control the charge to the batteries , they don't rely on the charge current/voltage to indicate when a set of batteries is fully charged. This method was fine when the highest power you could get was about 1800mAh.

The newer high power batteries need more, so I tend to charge them twice. This seems to work fine if just taking longer

Memo to self: Must but a better charger sometime

Check HERE.

Or HERE

I have the digispeed 4 great fast charger, comes with home and car power supply plug, plus it alerts when duff battery is inserted.

+1 Ansmann chargers. I had a Uniross and as others have said they just use a timer which is not very good for your batteries. Ansmann chargers detect the drop in voltage that happens just before a NiMh battery is fully charged then drop to a trickle charge to finish off the charge.

My rechargable batteries last about 4 times longer now because they are charged properly. It will be a little more expensive to start with but you will get that money back with 2 sets of 4 batteries life cycle.

Choccy...
