USA Today reports that recent recalls of laptop batteries has led to an industry-wide push to make batteries both safer, and quite possibly, less expensive. Underwriters Laboratories is currently re-evaluating lithium ion battery guidelines. Meanwhile, IPC, a computer component trade group, has pledged to release a set of battery manufacture guidelines in June. In addition, the Institute of Electrical and Electronics Engineers, another trade group, is also reviewing its battery technical guidelines. All three groups share the same goal of improving battery manufacturing processes in order to avoid problems such as the one that has caused Sony to recall several of its laptop batteries. At the moment, there are relatively few guidelines governing how laptop batteries are manufactured, and as such, each manufacturer builds them a little bit differently. This can cause confusion for PC makers when something goes wrong, because when problems do arise, there is no way to determine that all batteries were made in the same way. Improved standards will help eliminate the amount of guesswork from both battery making and purchasing, and perhaps lower costs, as manufacturers will no longer have to customize products for each buyer…
