Re: HP 50g : Best rechargeable batteries ? Message #8 Posted by Derek Walker (UK) on 14 Nov 2013, 9:13 a.m., in response to message #7 by Thomas Ritschel
A number of years ago, a UK retailer sold Rayovac brand rechageable alkalines, and I bought several packs at that time. They were better than contemporary NiCads for equipment in intermittent use. However I did have an instance of cells leaking within an appliance (i.e. not during charging). I reported this to Rayovac, who sent me a couple of packs of new cells in response, and IIRC also asked me to return one of the leaked cells to them for investigation.
It was some time before I put the replacement cells into use, but I did eventually and I'm still using them now. However, they have lost quite a lot of capacity, and I now use them mainly in some decorative LED lights which have fairly low consumption. I've had no more leakages, and the cells must by now be at least 10 years old.
The two chargers I bought for them have the advantage of having individual channels, so are handy for charging odd numbers of cells. They seem to have quite sophisticated circuitry, and I have used them to revive cells that other chargers didn't seem able to do much with.
