[FAQS about How many Ah batteries are needed for a 50 watt solar panel]
Discharge time is basically the Ah or mAh rating divided by the current. So for a 2200mAh battery with a load that draws 300mA you have: 2.2 0.3 = 7.3hours 2.2 0.3 = 7.3 h o u r s * The charge time depends on the battery chemistry and the charge current. [pdf]
[FAQS about How long is the appropriate discharge time for a lithium battery pack]
Cordless tools with 18V lithium-ion batteries can draw peak currents of 30-50+ amps. They usually have lower average current draws. For corded tools, the amperage rating indicates the maximum current they can handle without overheating, not the actual current drawn during use. [pdf]
