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.

Do not confuse with the 6 volts, 15.3 mm long battery made by Golden Peak, or the 9 volts, 15 mm long battery made by Golden Peak that are both, confusingly, listed as GP25A.
