355 Battery Replacement DIY Kit with 303/357

355 Battery Conversion Ring to Fit 357 Battery.


Genuine Japan Maxell or Energizer fresh date coded battery included

Use this adapter ring to allow the 357 to replace the 355 which has not been available for some time from Energizer, Duracell, Mallory or Rayovac. The voltage 1.55 x 160 mAh is the same for the 357 as the 355; completely interchangeable. This ring DOES NOT change the voltage but allows the same voltage of the 357 1.55 to be delivered to the watch. The 355 and the 357 are the same 1.55 voltage.

The 357 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.

This is from the American Watchmakers-Clockmakers Institute 2008 Edition Handbook "Battery Number System". This Battery is cross-referenced as: AWI S03, Duracell D355, Duracell 10L129, Mallory 355, Rayovac 355, Rayovac RW25S, Rayovac RW29, Rayovac RW15, Varta 544
