More on Batteries
There are only a few battery manufacturers in the world who make their own "cells", including LG, Panasonic, Samsung, Sanyo, and Sony.
All the other brands on the market buy the second and third tier cells from those manufacturers and re-wrap them under their own brand. These are "second and/or third tier cells" which did not meet the higher standards of the original manufacturer. So, in order to compete with the original manufacturers' batteries (first tier), these other companies feel obligated to publish specifications which are inflated to make them appear superior to those of the original manufacturer.
* (AW is Andrew Wan, a former Panasonic employee who branched out to create his own "brand" of batteries. He allegedly has agreements with the major cell manufacturers to purchase first tier batteries from them. Not all batteries are created equal, so AW tests these batteries for quality. The best get chosen to be AW brand, and are re-wrapped as AW.)
Efest, MOJO, AWT, Basen, Eizfan, IMRen, Sub-ohm Cell, Vamped, Vappower are all re-wrap resellers that are buying these "second and/or third tier cells" (sometime referred to as "B & C bin discards"). They print the "pulse discharge rating" on the label and pass it off as their CDR (continuous discharge rating). They often charge double what the authentic is worth. Unless you know what you are getting, stay away from these brands as you never know what is under the wrapper.
Batteries - Where to Buy
Only buy batteries from a reputable supplier (not ebay or Amazon) as there are many counterfeit batteries being sold. Here are several reputable battery suppliers in the US.
