    Single use battery chargers

    I see universal battery chargers for sale that claim to be able to recharge single-use alkaline batteries. ( aa, aaa, c, d, and 9 volt). Anyone ever use one of these? Do they actually work as advertised? If so, can you recomend a quality brand?

    I have and use a bunch of rechargeable batteries. But it would be nice to be able to reuse some ‘energizer’ or ‘duracell’ batteries if possible. The rechargables don’t last as long as a virgin alkaline battery.

    I've read up on those Alkaline battery chargers. They work but they can only recharge the battery to about 65% of its original capacity the 1st recharge. And a little less capacity the 2nd recharge...
    Most batteries can be recharged about 3 times before they die.

    It works, we did this 40 years ago because my dad was very thrifty. I now buy eneloop batteries because they don't leak and ruin my flashlights.

    Instead of spending money of something iffy, just spend it on technology that's known to work. Buy more rechargeables instead.

    My ability to recall lyrics from a song written in the 70's far exceeds my ability to recall why I walked into the kitchen.

    Those recharged alkaline will drop in voltage faster and leak sooner.
