This data was taken from Manufacturers' data sheets and is intended for the pleasure of our readers only. In every case the information presented was the best battery listed by the manufacturer, but typographical errors, etc. are probable, since the typist is not a professional (our CEO). The data sheets were not likely to be the latest available. Please point out errors, we do intend to be fair if possible. PowerStream does not manufacture or sell batteries, just custom chargers. The data listed are incomplete and should be used as a guideline only. Please contact the manufacturers for the latest data and pricing. Note that specsmanship will prevent you from comparing different manufacturers in an apples-to-apples manner.
