Where to get batteries
Most bicycle stores that sell Avocet Cyclometers also sell replacement batteries. You can also order batteries directly from Avocet. Use an Avocet brand battery for your Cyclometer model if possible. If your bicycle dealer doesn't carry the correct replacement battery, you can often buy an equivalent battery at an electronics store such as Radio Shack. Use the battery equivalent list below for choosing the correct battery.
Cyclometer 20 & 30:
386 silver oxide, 1.5 volt.
These were originally spec'd for 1.35 mercury which is no longer made. The 1.5 silver oxide is the closest equivalent and works well with possible shorter life than the original mercury.
Cyclometers 15, 25, 31, 35, 40, 45 and 45tt:
357 silver oxide, 1.5 volt.
For models 35 and 45 total reset is recommended before battery installation. For total reset, hold both buttons down for 30 seconds with battery out. The 357 silver oxide battery supercedes the original equipment battery for these Cyclometers. Manufacturer's cross reference numbers are listed below. Any battery on the list can be used in these Cyclometers.
Duracell D357H
Eveready 357
Maxell SR44W
National SR44W
Panasonic SR44W
Phillips 357
RayOVac 357
Renata 357
