Rechargeable Battery Tips


  • Read and follow the charging instructions provided with your product. Each charger utilizes a specific strategy to charge the battery.
  • Charge your new battery overnight (14-16 hours) before using it for the first time. This is called “initializing” and will enable you to obtain maximum battery capacity.
  • Let your battery cool to room temperature before recharging. The charge efficiency of most batteries is greatly reduced at elevated temperatures.
  • Recharge batteries only when they are near to fully discharged. You can tell that a battery is discharged by a sharp drop in power or speed of the equipment it energizes.
  • When your rechargeable battery can no longer hold a charge… RECYCLE IT! Recycling rechargeable batteries is simple and easy and can be done at local Radio Shacks, Circuit City, and Midland Tool Specialty.
  • The Rechargeable Battery Recycling Corporation (RBRC) recycles the following portable rechargeable battery chemistries:
    • Nickel Cadmium (Ni-Cd) 
    • Nickel Metal Hydride (Ni-MH) 
    • Lithium-Ion (Li-ion) 
    • Small Sealed Lead (Pb)*
    • Weighing less than 2 lbs./1kg.
  • These batteries are commonly found in cordless power tools, cellular and cordless phones, laptop computers, camcorders, digital cameras, and remote control toys.


  • Return a fully-charged battery to the charger for an “extra boost.” This will overcharge the cells and shorten the life of the battery.
  • Leave your cellular phone, camcorder, etc. in the charger when not charging (unless approved by the manufacturer’s instructions). Don’t use your charger as a stand. Continuous charging will shorten battery life.
