Maxell ML (lithium manganese dioxide rechargeable) batteries are available only for equipment manufacturers as a built-in part. Therefore, Maxell does not supply these batteries for replacement directly to users of equipment with these batteries. When built-in ML batteries need to be replaced, please contact your equipment manufacturer.If you are planning to use Maxell ML batteries in your equipment as a built-in part, please contact Maxell.

OVERVIEW

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.

 

 

 

 

CONSTRUCTION

 

 

 

 

PRINCIPLE AND REACTIONS

The coin-type lithium manganese dioxide rechargeable battery is a 3V battery using specially treated manganese dioxide for the positive mateiral, a lithium-aluminum compound for the negative material, and a specially formulated organic electrolyte.

 

 

 

 

 

FEATURES

Approx. 2.5V operating voltage
 
The operating voltage is about twice that of nickel cadmium rechargeable batteries. Displays a high discharge voltage of 2.8 V when at 10% of nominal capacity (depth of discharge is 10% or less), when charged at 3.0 to 3.3 V.
Superior charge/discharge characteristics (Fig. 2)
 
Achieves 1,000 cycles of discharging to 10% of nominal capacity (Depth of discharge = 10%). The total discharge capacity is quite high at 100 times nominal capacity.

Wide -20 deg. C to 60 deg. C usable temperature range

 
Demonstrates stable operating voltage in temperatures as low as -20 deg. C and as high as 60 deg. C.
Low self-discharge and superior leakage resistance (Fig. 3)
 
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 (shipped fully charged).
Excellent floating characteristics (Fig. 4)
 
A specially formulated organic electrolyte is employed to provide stable discharge characteristics even if charged for a year at 3.3 V at 20 deg. C (according to accelerated test conducted by Maxell).
