Maxell Corporation of America, Inc. Coin Type Lithium Manganese Dioxide Rechargeable Battery ML Series

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. 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. (shipped fully charged) • 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. • 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). • Excellent high rate discharge characteristics (Fig. 5) Applications ●Mobile Phones ●PHS ●OA Machines (Fax, Copiers, Printers) ●Notebook PCs ●Desktop PCs ●PDAs ●Camcorders ●Digital Still Cameras ●Portable CD/MD Players ●Watches ●Medical Instruments, Cash Registers ●FA Instruments (Measuring Instruments, Onboard Microcomputers, Sensors) ●Electronic Meters (Water, Gas, Electricity)
