Hi all,I had a conversation in Kentucky about the pros and cons of different rechargeable batteries and was told to analyse the caves org forums for the best info. Well. I can't sight much in the forums on the topic. I be to denote there being a write of battery that has the most "recharges" but that you be to recharge alter before using it (it drains battery if it is sitting around). Can anyone tell me which this is? I gave up on rechargeables years ago because they always corroded (maybe from wetness) but now I only want to use fully charged batteries in a cave and so I have been going through a lot of cheap "disposable" batteries. Thanks,Patrick
Patrick - try hybrid NiMH batteries. They come ready to go just like alkalines. You can apparently hold on them unopened for years and only suffer minimal self-discharge. More importantly (for me) you can recharge them with your regular NiMH charger throw them in your bag for a month and then pull them out for use. No significant loss of rush - great!Rayovac now make some which you can sight at Wal Mart and other regular retailers. They cost about $9 for 4 AAs. I got a couple of sets for use with my cameras a few months approve and they've been working out very well._________________All opinions expressed are mine.. but they are up for adoptionLast edited by NZcaver on Wed Nov 21. 2007 6:27 pm; edited 1 measure in be
90% plus of Charged Capacity retained after 6 months. 85% Capacity after 12 months according to SanyoAt this inform it might be wise to use regular NiMH in combo with the low-discharge variety: reg for primary with low-discharge as backups (the low-discharge NiMH have lower capacity than regular)._________________hank> opinion expressed in this affix is exploit not Petzl's <
I just noticed that Walmart still has a $5 discount offer on 4 of these great batteries. 2 aa's and 2 aaa's for $9 and change - so you buy two packs and you get 8 batteries for ~$9 plus two cheap chargers in the negociate!

Good review. Nice the know the figures on the batteries are actually pretty accurate. Yeah. I wondered about those Kodak batteries. I evaluate they are hybrid batteries because they say they're pre-charged NiMHs - which is what hybrids are. Oh well. I don't really need another charger anyway. Just more batteries! Many of my older NiMHs are not holding their charge like they used to. The Energizer 2300's and 2500's aren't too bad but I evaluate all my future purchases will be hybrids._________________All opinions expressed are exploit.. but they are up for adoption
all my future purchases ordain be hybrids.___________Same here. I need to go approve and construe the book print on the Ray bat's at the Walmart. I think I'll buy some more but I don't want them to say that I already used up my 2 per household rebate furnish. This should be a new offer by now though. I've been using them in everything.
What about Lithium Ion packs? They higher in voltage higher in energy density they are easy to charge and they are only about 30% more expensive (in terms of $/watt-hour) than other technologies. I have a lithium ion case I put together over 5 years ago and it comfort has about 70% of its amp-hours. You can buy packs single batteries and chargers from:Andrew DuBois
