Battery Selection and Sturtevant Richmont Tools

There are some important things to know about battery selection and Sturtevant Richmont tools. 

We build highly durable tools with sophisticated electronics. We design circuits to be as energy-efficient as possible. We are also concerned about the environment. 

Our tool and tester circuit boards are designed on the highly consistent 1.2-volt power curve provided by rechargeable NiMH batteries. Other batteries like Alkaline or

Lithium batteries provide 1.5 volts in the power curve. The additional voltage can damage the circuit board. 

Compare 1.2 Volts of a AAA NiMH and the 1.5 Volts of a AAA Alkaline battery. That Alkaline battery provides 25% more current to the electronics. 

Please Remember These NiMH Battery Facts:

  • NiMH rechargeable batteries come in a range of mAh (milli-amp hour) ratings. 
  • Always use the largest mAh rated batteries available.
  • The TAC wrench requires a minimum of 1,000 mAh rated battery.
  • The rating difference is the number of operational hours the battery will supply.
  • The higher the mAh rating, the longer the batteries last between charges.
  • High mAh rated batteries take longer to charge than low mAh rated batteries.
  • Quick chargers can shorten useful battery life.
  • The trickle charger is the best way to recharge the batteries and preserve battery life.
