Recharging Non-Rechargeable Batteries

Alkaline Recharge The Eveready charger seems to only work with their own brand of “special”alkalines, read “expensive”.. I saw some posts here where people have said that they have successfully recharged regular alkalines on them, butI haven’t seen it done.

Take a piece of tin foil and tightly wrap it around the positive end of your standard Alkaline Battery. Then insert it into the charger and jiggle it until the red light, lights.

If you look at regular alkaline batteries they have a plastic insulator around the outer edge of the positive end. The alkaline rechargables are metal and do not have the insulator. The recharging unit has side contacts that contact the outer edge of the rechargable batteries therefore recharging them.

I have had very good success at recharging standard alkaline batteries but I did have one that ruptured and did inturn leak. So be careful!

I have had good results from it, depending on the condition of the battery being charged.. ie: it will charge a lightly discharged battery to better than factory voltage (as much as 1.56v), but if you recharge one that’s nearly dead, it will bring it to 1.36v to 1.48v, not quite factory voltage, but still better than Nicads ordry-cells…I am sure that the micro-processor does what it says.

Its the batteries that are a scam, its all in the design of the posative end of the battery.

The Rayovac has no plastic insulator around the top of the battery, therefore using the sides of the battery for the positive connection of the charging system. All the Rayovac Batteries that I recharge give off the same smell (gas)when being recharged as do the normal alkalines do that I recharge using th equote foil method.

Actually, any battery can be recharged. The trick is to do it slowly.

Most types of batteries will heatup and be permanently damaged if recharged too slowly. The active chemicals in batteries must be in a liquid, or semi-liquid state. If a battery is allowed to dryout it will not function. Too high a rate of charge will also cause gas to form at the center element (electrode) and increase the resistance in the battery preventing it from charging until the gas dissipates.

This can be readily be seen in an automotive battery. Gas can form so rapidly that the bubbles can be seen in the electrolyte and forming on the plates. When this happens water must be added to keep the battery serviceable.

The problem is how can you replace th ewater in a carbon-zinc or alkaline battery. Also, what is the service life of a recharged battery? In the case of a carbon-zinc battery the discharge rate of a nearly dead battery is greater than the maximum charge rate. The battery will literally go dead while it is being recharged.In a survival situation it may beworth the effort to try this. Any battery is better than none at all.
