Battery Details

The differences between LR and SR cells:

LR cells are Alkaline Manganese based and have a lower energy density or capacity and are 1.5volts.
SR cells are Silver Oxide based, have a higher energy density or capacity and are 1.55volts.
See the Notes page for more info.

"D" battery.

Some sources list this as "86A" & "GP86" while other sources cross reference the LR44 as "86A" & "GP86". Both are 11.6 mm diameter, the difference being the thickness; 4.2 mm for LR43, 5.4 mm for LR44.

Alkaline or Silver Oxide replacement for the banned Mercury type.

There is no voltage compatible equivalent that I can find for the banned Mercury type, but the Alkaline or Silver Oxide types should be fine for most applications.
