Maxell ML Series Coin Lithium Manganese Dioxide Rechargeable Battery

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).

Description

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.

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).

Maxell

Maxell was formed in 1960, when a dry cell manufacturing plant was created at the company’s headquarters in Ibaraki, Osaka. In 1961, Maxell Electric Industrial Company, Limited was created out of the dry battery and magnetic tape divisions of Nitto Electric Industrial Company, Limited (now Nitto Denko Corporation).

On March 18, 2014, the company was listed on the First Section of the Tokyo Stock Exchange. In 2013, Maxell, Ltd. acquired Hitachi Consumer Electronics, Co., Ltd.’s projector design, development and manufacturing assets and resources. On October 1, 2019, Maxell Corporation of America announced it would assume responsibility for all operations related to both Hitachi- brand and Maxell-brand projector products and accessories in the North American market.

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 : 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 : 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 : 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 : 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.
