When was the last time you started to have some fun with your favorite gadget, put in freshly charged batteries, but ran out of juice much sooner than expected? What happened?? Most likely one bad battery in the set. Now you can test those batteries for actual capacity. Match batteries in sets of equal tested capacity so you will get the expected run time. Make sure those high capacity batteries you bought are what they are advertised, test them for actual capacity. Just bought some new Li-ion batteries and suspect they are not as good as advertised??
