Battery Details

Don't confuse these with the AA battery as these are twice the voltage in the same sized package.
Using of one of these in place of a 1.5 volt battery could damage your equipment.

About the Chemistry:

NOTE: These Lithium types are NOT rechargeable, they are single use batteries.

• Lithium Manganese Dioxide (LiMnO2) suitable for high current drain e.g. torches and radio control uses.
  
  
• Lithium Sulpher Dioxide (Li/SO2) suitable for high current drain e.g. torches and radio control uses.
  
  
• Lithium Thionyl Chloride (LiSocl2) suitable for low drain e.g. memory back-up, smoke detectors etc.
  
  Some Lithium Thionyl Chloride (LiSocl2) are "Spiral Wound" construction and are suited to high current drain (designated by the suffix "M", i.e. ER*****M).
  You can use any of the high drain types to replace a low drain LiSocl2 but don't try to replace the high drain types with a low drain LiSocl2 or explosion due to overheating could occur.

Note for Delta-P Technology VR3 Dive Computer users:
Early VR3 Dive Computers were fitted with a battery cap with a small interior diameter. If the battery has a plastic outer coating, which makes it just a tiny bit thicker than a standard painted metal battery, then you will need to cut off the bottom 18mm (from the flat, negative end) of the plastic coating. The negative end of the battery then fits into the VR3 battery cap which is the negative terminal anyway, so stripping this bit of plastic off won't cause any problems. (Later models had a larger diameter recess).
