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

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

Made in Japan
Genuine Maxell Hologram Anti-Counterfeit Packaging (other package may not be genuine)
1.55 volts 55 mAh
Mercury Free
This is a primary non rechargeable disposable battery

The 381 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.
