Overview

Developed by Maxell, the coin type lithium-ion rechargeable battery has a high-rate discharge characteristic of up to 2ItA by means of an original stacked electrode structure. This compact high-power rechargeable battery is designed for small portable devices such as IoT devices, wearables and hearables that have communication functions.

High Power

A unique stacked electrode structure enables power of up to 140mA (CLB2032).

Discharge capability of CLB2032 is approximately 40 times better*

  • Compared with Maxell’s CR2032 at 60% available capacity

Excellent cost performance

Superior recharging properties ensure a service life of about 500 charge/discharge cycles under normal usage conditions. The superior cost/performance ratio ensures that lithium-ion batteries are ultimately more economical than primary batteries.

High reliability

Maxell has incorporated unique technologies gained during its development of crimping and electrode coating. The stainless steel battery body minimizes swelling.

Superior safety

Separator-wrapped positive electrodes prevent to make internal short-circuit. Safety is ensured even if external short-circuit occurs.
