Industrial Batteries
By W.W. Grainger
Designed for high drain devices, alkaline batteries have up to twice the service life of heavy-duty batteries and are leak-proof. Heavy-duty, nonalkaline C batteries are ideal for lower drain devices. Both types retain 85% of original life up to five years in storage. Mercury-free. Order the button style 1.5 V silver oxide batteries for certain timers (see Timers section.)
