| 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. |

| Product Safety Data Sheet |
|
|
|
| |
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 mateiral, a lithium-aluminum compound for the negative material, and a specially formulated organic electrolyte.
 |
| • |
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). |
