Which rechargeable batteries are recommended?

I have the same question. There was some discussion on this topic back in July. Several of the guys were using NiMh or thinking about using them. Perhaps they will weigh in on how well the rechargeables have worked out. There are a few manufacturers that make high end lithium-ion rechargables that are rated at 550-600 mah with a nominal voltage of approx. 7.4-8.4 volts but they aren't inexpensive. Still, if they last about 10 hours per charge that would be better than my Explorer gets with it's rather large battery pack. I'm no tree hugger but with todays rechargeable battery technology it makes sense not to add more batteries to the landfills than is necessary, plus it makes economic sense if you detect a lot. Perhaps Dave J. will advise on using the ultra high capacity lithium-ion batteries in the G2/GB. If you do decide on Li-ion rechargeables, only use a dedicated Li-ion charger or a charger that has a switch for Li-ion batteries, otherwise there is a fire hazard potential.

I recommended alkalines only. I believe it was because rechargeables don't give consistent voltage as alkalines. He did say wouldn't hurt to experiment but couldn't guarantee optimum response out of your detector.

Here's what Dave J. had to say on the subject back in May. http://www.findmall.com/read.php?80,1463143,1463270#msg-1463270 There are a few types of Li-ion rechargeables and the prices have come down but probably not worth the risk of damage to the electronics.

Jim, how much detecting time are getting per charge and have you tried checking the voltage at the each of the three battery bar levels? Also, have you experimented with any depth comparisons between the NiMh and alkalines? It would be interesting to know if the alkalines performance was actually better since the electronics was developed around them. Gary

I got 1 and a half hunts per charge but I can recharge each hunt. I find the cost so far to be a savings....we shall see how long the 2 batteries I have last.

thanks for the link garyflal...when the chief engineer says "NiMH can be used" (but won't last as long as alkalines), then that's good enough for me. I'm going to try rechargeable NiMH batteries...

Duracell and you will not go wrong. No rechargeable here.
