Interphone battery storage and maintenance

Lithium-ion (Li-ion) batteries and nickel-metal hydride (Ni-MH) batteries are placed in the product or storage for a long time, and will continue to discharge slowly (self-discharge), causing the capacity to decrease or enter the "sleep" state, resulting in shortened battery life Even damaged. Therefore, please do not leave the battery unused for a long time, and maintain it regularly. In general, if the radio battery has not been used for more than 6 months, you must check the charging and power status to decide whether to charge or discard the battery.

For long-term storage of batteries, it is more reasonable to keep them under power. Lithium batteries generally require their power to be controlled at more than 40%. The best condition for nickel-metal hydride batteries is about 80% when charged, and conditional storage is better at 15 ℃ or lower. The extent of aging is also different at different temperatures and saturation levels. For example, lithium-ion battery:

Storage temperature (℃)

40% charge state preservation

100% charge state preservation

98% (after one year)

94% (one year later)

Specific operation

According to the feedback from Hytera authorized dealers and HYT survey results, there are generally cases of long inventory periods or long periods of unused use, resulting in short battery life or failure of some batteries.

1. According to the self-discharge status of nickel-metal hydride batteries and lithium batteries, nickel-metal hydride batteries are required to be fully charged every three months or so, and lithium batteries need to be fully charged every six months.
2. When not in use, remove the batteries from the intercom and store them separately.
3. Try to store the battery at a temperature of 5 ° C to 20 ° C (41F to 68F) to avoid sun exposure or rain.
4. First-in-first-out, keep the battery in reasonable use as soon as possible.

Note: When using battery charging to charge, when troubleshooting a problematic configuration battery, please test one battery and one battery slot at a time. A defective battery may prevent the battery in another slot from charging properly, causing several batteries to fail to charge.
