Keep Thomas Edison's good name away from this trash!
The product description of this item ("ReNu It Battery Renewer") sounds just like those trashy commercials seen on late-night TV. It makes outrageous claims that are either half-truth or flat-out lies, just to separate the viewer from his money.<br /><br />For example, it says:<br />"Thomas Edison first invented the Principle of the ReNu-It Technology over 75 years ago. He understood that an alkaline battery could be renewed, simply by cleaning the cells"<br /><br />Fact check: Modern single-use Alkaline battery was invented in 1949, but Thomas Edison died in 1931!<br /><br />For another example, it says:<br />"Bring life back to disposable batteries up to 100 times and enhance new batteries up to 15%!"<br /><br />Fact check: The claim of "up to 100 times" is only possible if you never let the disposable cell runs lower than 1.4V at its terminals. That means you can only use around 20% of the battery capacity each time, before recharging it again. An exhausted disposable cell can never be brought back to its original capacity. Furthermore, the capacity drops with each subsequent deep discharge/recharge cycle. At best, you can get maybe one dozen cycles out of it, before its capacity becomes too low to be useful. At worst, the cell may start leaking electrolyte after just a few cycles, and ruin your battery-operated appliance. You have been warned!<br /><br />Just in case you still want to experiment with recharging alkaline cells, here is my suggestion: Get the [[ASIN:B000A0IL9C Rayovac Universal Battery Charger]] instead. It is a very versatile unit designed to handle multiple battery chemistries (NiCd, NiMH, and rechargeable alkaline). That way, if recharging alkaline does not work for you, at least you can still use this charger for other rechargeable battery types.
