• How to choose between two batteries with different Watt hours (Whr) or milliAmpere hour(mAh)?
  Higher Watt hours (Whr) or milliAmpere hour(mAh) on the same system under the same operating conditions means longer battery run time. For example, if you compare the same system, running the same applications, the ibm thinkpad r40 battery with 73Whr would provide approximately 37% more run time than the 53Whr thinkpad r40 battery.
• How to keep my battery healthy?
  Thinkpad r40 battery packs should be charged for 12 hours when you first get them. Laptop batteries are completely discharged at the time of purchase, and need a full charge before their first use.
