The operating voltage is about twice that of nickel cadmium

rechargeable batteries. Displays a high discharge voltage of 2.8V

when at 10% of nominal capacity (depth of discharge is 10% or

less), when charged at 3.0 to 3.3V.

Demonstrates stable operating voltage in temperatures as low as

–20 deg. C and as high as 60 deg. C.

Self-discharge at 20 deg. C is no more than 2% per year. Supplies a

nominal capacity of about 95% even when stored at 20 deg. C for

roughly five years (according to accelerated test conducted by

Maxell). And since organic electrolyte is used, the battery has

superior leakage resistance.

A specially formulated organic electrolyte is employed to provide

stable discharge characteristics even if charged for a year at 3.3V at

20 deg. C (according to accelerated test conducted by Maxell).

Features

The coin type lithium manganese dioxide rechargeable battery is a small, lightweight rechargeable battery. This battery employs specially treated

manganese dioxide for the positive material and a lithium-aluminum compound for the negative material. A specially formulated organic electrolyte

is also used, yielding excellent discharge characteristics with low self-discharge.

The coin type lithium manganese dioxide rechargeable battery is a

3V battery using specially treated manganese dioxide for the positive

material, a lithium-aluminum compound for the negative material and

a specially formulated organic electrolyte solution.

Dimensions and weight are for the battery itself, but may vary depending on terminal specifications and other factors.

Nominal capacity indicates duration until the voltage drops down to 2.0V when discharged at a nominal discharge current at 20 deg. C.

Data and dimensions are just reference values. For further details, please contact your nearest Maxell dealer or distributor.
