The SR44 button battery is needed in the two digital calipers and all the digital dial indicators from Reeds 'n Stuff. They all come with the SR44 compatible battery but eventually the battery will need to be replaced. (Mine lasted about a year.) The SR44 battery that they come with is a high quality silver-oxide battery. Silver-oxide batteries have slightly higher voltage than alkaline batteries (1.55 vs 1.5 volts), higher cut off voltage (1.2 vs 1.0 volts), more stable output voltage during use, and larger capacity (150-200 mAh vs 110-130 mAh). Also, silver-oxide batteries commonly have longer shelf life (over 5 years).  The equivalent LR44 alkaline battery has 1.5 volts which drops over time. Typical capacity of LR44 batteries is around 110-130 mAh, with shelf life between 2-5 years. The advantage to the LR44 alkaline battery is cost at half the price.
