    I have a Problem with Rechargeable's Getting a Memory,
    Or just Going Bad. Even The Minelab Rechargeable's that are not Supposed to Get memories
    barely give me 2 Hours on a full charge. so I've switched to Alkaline's for a better chance of Steady Power

    Jeff, NiCads are the ones that have a memory problem. NiMH do much better and have a higher capacity. The NiMHs that come fully charged or precharged are of a longer lasting formula for storage of the cells. In any case, a quality charger should be used.

    I forgot to add to buy ones with a base voltage of 9.6v as the other voltages of 8.4v and 7.2v will not power your stuff sufficiently even though the batteries are not technically dead.

    The Minelab Batteries are
    NiMH


    https://www.amazon.com/Minelab-Batte...03383011&psc=1

    They still don't Hold a Charge anymore.

    12 Hour Charge Nets about 2 Hours Use. if I'm Lucky.
    & If I start with 2 Hours Worth of Batteries 30 minutes in they are 1/4 of the way Dead already.

    If it sits for 2 Days after the Charge, & I Go out, I Usually end up Loading a Dead Rechargebale
    Or walk into the Field & Have to Walk back to the Vehicle for Alkalines 3 Minutes into my hunt.

    I Gave up on Trusting any Rechargeables considering Price.

    Plus the chargers Don't last Either.

    Of Course I Just Purchased another Explorer Last Year
    that came with a Rechargeable. But No idea on it.

    I'm more Comfortable Buying Alkalines off ebay Bulk these days.

    NiMH batteries are better than NiCad but they still go bad over time. Lithium ion batteries are the next generation.

    You're right that the Li-ion have their good points too, but no battery is perfect as even these diminish with time.

    @Jeff, I can't say for certain what the problem is you are experiencing, but the batteries sound as if they're old and ready to die. Even rechargeables eventually die. I can't rule out that you got some bad batteries as it does happen or it could be something wrong in the charging process. Finding out can be expensive so go with what you know.

    Which batteries have you found with that voltage? All the NiMH I found are lower. What voltage are they after say an hour of use?

    See my post #19. The voltage is a nominal 9.6v, but it will be a bit higher after an hour of use coming off of a full charge. Even alkalines are a bit higher than their stated voltage for quite some time. BTW, you can find this battery at B&H for $10.95.

    Sorry, I missed it. The Tenergy ones I have are 250 mAh so they may be the same. I just have never put a meter on them. They were recommended by several CZ21 users so I bought a couple of sets. I just haven't used them much yet. Click image for larger version.

    Those work. Rechargeable are nice but have found my detectors and pp work different. I try to run Duracell when possible, but every day hunts I just use the cheapest battery's I can find. I will say the only fault with cheap battery's is they leak so I never leave them in my machines. I would say always have a back up. I will say I have had the best luck with Duracell. But unlike my F75 that gets a lot of swing time on Duracells, my AT Pro gets just a few hours or about one hunt with any battery. My rechargables for my Etrac last about 4 hours, I have considered investing in the new dnb batts for my etrac. Hope this helps someone.

    My experience with Duracells has been all bad. As I've said before I have lost several devices due to them leaking, much more than any other brand. They work fine as long as they are new but if I forget them in something like a flashlight for a few months and they will leak and a light without batteries in an emergency is useless.

    If I'm not going to use my detectors for any more than a week or so the batteries are taken out just to be sure.

    I concur with your experiences with Duracells. I lost a very expensive flashlight due to leakage that occurred 1 month after I bought it and the batteries were supplied by the flashlight manufacturer (Maglite) to boot. Maglite offered to replace the batteries in the same flashlight and as a result I dropped both companies.
