Debunking the Batteriser's Claims
An anonymous reader writes: Last week we discussed news about the "Batteriser," a small device that fits around a battery and extends its lifetime. Many of us were skeptical, particularly with the claim that it could extend battery life up to 8x. Now, David L. Jones at the EEVBlog explains exactly why the device won't be as good as its creators claim. The technology itself, he says, does actually work at extending battery life, and has existed for a long time. What this company seems to have done is just shrink it down to a more useful size. Unfortunately, their claims about when a battery stop working and how much energy is left don't really hold up. Batteroo, the company making the Batteriser, claims products stop working when a battery's voltage drops below 1.3v, but a simple test of common household gadgets finds that to be untrue. Further, the percentage of energy left in the battery after this cutoff can vary wildly. Sometimes it will be 80%, but most of the time it won't, and it's frequently 20% or lower for Alkaline batteries. Jones writes, "I'm genuinely baffled as to why Batteroo would need to resort to claims like 8 times life. This thing would still sell like hot cakes if they claimed realistic practical figures. 50% increase in your battery life? – great, countless people would still buy it at the super low price point it's at."Read more of this story at Slashdot.
