Li-ion Battery

This Locktronics component is comprised of a Lithium Ion battery in a secure stainless steel casing. The battery used is a Panasonic 18650 cell with internal poly resettable fuse for current limit.

Battery care

• Long Term Storage Voltage: 3.85V
• Short Term Storage Voltage: 3.7V – 4.0V
• Absolute Max Voltage: 4.2V
• Absolute Min Voltage: 3.0V

At the end of each session we highly recommend checking the voltage of each battery. Batteries with a voltage of 3V and below should be topped up to around 3.8V or they risk becoming permanently damaged and will need replacing. Batteries with a voltage higher than 4V should be discharged to around 4V or they risk losing both capacity and current capability. Checking the voltage of the batteries after each session also allows students to be held accountable for any misuse or abuse.

The battery voltage is very important when storing the battery for any mid to long period of time. The storage voltage should be around 3.85V and should be checked and topped up at least once every 6 months to prevent the battery becoming damaged. The batteries should be stored in a cool and dry environment for maximum life expectancy.
