Charger....

any comments on the Ikea charger?  Looks 'mid-grade' in price.  Very long charge time, assume better for batteries.  12 hrs for 2450mAh. 

Looked at the Powerex, thanks for mentioning Gutbucket.  I see a couple of price tiers, including one with batteries included.  Any thought on Powerex battery value?  I see 2600 and 2700 mAh types. 

with batteries

no batteries, more $, similar charging times

Anyone knows if the Powerex (or some similar charger) is available on the European market? Can't find it.  :-[

I got mine from www.mahaenergy.co.uk which is operated by Nevada Radio in the UK. They are the official dealers for MAHA/Powerex & are a long established business also selling amateur radio gear etc.  I'd recommend them.
The MHC9000 is all the charger you'll ever need. It's  a bit bulky for a 4AA charger, but will analyze/test each cell so that you know they're good.  MAHA also do a less complex 8AA version.

I've been using the Powerex low self discharge (black) AA's and 9.6V's and have no problems with them.  Last I checked, a few years back when I last replaced them, they were on-par with Eneloop.  We use Eneloop at work for cameras and when I've used those for recording their performance seemed about equal.

When I bought the charger maybe 8 years ago or so, the Maha MHC900 and the Lacrosse Technologies charger were the fully "smart" chargers that set the bar.  Either of which I figured was a good investment to extend useful life of the batteries as much as possible and to monitor them to confirm when it's time to retire them prior to failure.

I've purchased my batteries and chargers from Thomasdistributing.com and can recommend them for good service.  Upon my contacting them about a decade ago concerning an earlier model non-low-self-discharge 9.6V which had swelled up a number of months into use, they immediately volunteered to replace it without a return.

BTW, I highly recommend the low-self-discharge (LSD) version of any NiMH AA, AAA, or 9V over the standard version of the same.  The minor reduction in capacity in comparison to non-LSD types is well worth the increased charge retention, reliability, and longevity.

Good to know, thanks.  More reading to do....

Going to start getting into rechargeables. Just a question for people... Where can you recycle AA/AAA batteries? I have a bunch that I want to recycle properly.
