Maxell 361 Silver Oxide SR721W 10 Batteries


Dimensions: 7.9mm Diameter x 2.1mm Height

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; batteries are dangerous if swallowed.

3 6 2 and 361 are completely interchangeable with identical functionality

Do not use (inherently low performing) alkaline batteries in place of silver oxide in any timepiece: alkaline have declining power output.

Made in Japan
Genuine Maxell Hologram Anti-Counterfeit Packaging (other package is not genuine)
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 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 may not be dependable.
