Superior Maxell 361 SR721W Micro Silver Oxide Japan Date Coded Genuine Hologram Package

Powerful Maxell 361 Micro Silver Oxide SR721W 10 Batteries


For a great price on a box of 100!


Please keep these and all shiny child-attracting small batteries out of the reach of children; they are dangerous if swallowed.


362 and 361 are completely interchangeable with identical functionality

Do not use (inherently low performing) alkaline batteries in place of silver oxide in any timepiece.

Made in Japan
Genuine Maxell Hologram Anti-Counterfeit Packaging (other package is not genuine)
Dimensions 7.9mm Diameter x 2.1mm Height
1.55 volts 25 mAh
Mercury Free
The 361 SR721W is completely interchangeable with the 362 SR 721 SW
This is a primary non rechargeable disposable battery

The 361/362 is a long life silver oxide chemistry with non-declining power output; alkaline batteries of the same 1.5 voltage start at 1.5 and at the half life are at .8 volts, silver oxide start at 1.55 volts and maintain the voltage until expiring. This is why silver oxide batteries are always used in watches, insulin pumps and sniper scopes or mission critical situations. Never use alkaline batteries for any device requiring a steady constant voltage. A watch with declining voltage cannot give the correct time.
