When I was little my brother and I used to tap batteries end to end. positive to positive, neg to pos, neg to neg, whatever... to get them to last longer. I don't know where we got this from, but is it myth or real?

no I dont think thats true. I have heard you can freeze them to make them last longer though and I think that would work.

There is almost no value to doing that, except this: The battery works because of a solid-state chemical reaction. If you drain the battery to zero, you have exhausted the chemical reaction near the battery poles but a small area further from the poles still has charge. If you disconnect the batteries and DO NOTHING, you may give the battery time to "re-equilibrate" and soon every part of the battery has a tiny amount of "charge" left. You don't have to tap the battery or do anything special, just disconnect and leave them alone for a while. I get a trace of charge out of very high-density rechargeable camera batteries that way, if I disconnect or turn off the camera for a while when it says "battery depleted". I suddenly see some charge which might be good for one or two more camera flashes before the camera quits again.

In the winter months it is the short journeys which put the maximum strain on car batteries. You can get 'solar powered ' trickle chargers which use available light to charge the battery via the cigarette lighter socket when you are not driving . Do not use tap water as that contains various dissolved salts, but use deionised or distilled water. An old trick my dad told me about was to add 1/2 a soluble Aspirin to each cell. I don't know the chemistry of it, but it worked for a time. ( He was ex Royal Engineers ) Ultimately though you will have to replace the battery

No there is no way that that will prolong the life. In fact once the chemical in a battery are expired there is no way to bring them back. Just better buy new ones.

You can briefly get a slight current increase by smacking a weak battery against a hard surface. It won't last long though.

I think as you are aging your memory is getting worse. I bet in the days when it happened with you and your little brother there were no good results from all that taping.

If it is real, that's new and interesting imfo to me. In any case, refrigerating batteries before they are used will make them last longer.

I am not sure...but i will totally try it! My 3 year old is constantly needing new batteries for his toys!

Dead is dead and no there is no life. really dead no life.
not really dead this sometimes does give a little more use. Little is the word.
