11.1.6.1 Checking Battery Performance
The performance of rechargeable batteries may deteriorate over time. If you suspect that the battery
may have failed, check the battery performance.
Please refer to Step 1~Step 3 in Section 11.1.6, and record the running time of the battery, which
reflects the battery performance. If the running time is obviously less than the specified time in the
specification, the battery may have reached its service life or malfunctioned, please change the
battery or contact the service personnel. If the running time meets the specification, then the battery
can continue to be used normally.
11.1.6.2 Storing the Battery
Remove the lithium battery and store it at a cool and dry environment if the lithium battery or the
device is not used for a long time. Charge the batteries to 40%-60% for storage. Check and maintain
the batteries regularly every 3 months. For more information, please refer to Section 11.1.6.
NOTE:
1 When storing the battery, avoid contact between the battery interface and metal objects.
2 The service life of the battery will be shortened if it is stored under high temperature for a
long time
3 Store the battery in a cool place can slow down the aging process. The ideal storage
temperature is 15°C.
For rechargeable button cell or lithium battery in wireless transducer, no need to remove it if the
device is not used for a long time. Check and maintain the batteries regularly every 3 months. Charge
the batteries to 40%-60% for storage.
11.1.6.3 Charge Cycle of the Battery
The battery is designed for frequent recharging. A complete charging cycle is only reached and
counted, when all recharging periods equal a 100% charge (900 mAh equal 8 hours continued
operation).

1. Mild near neutral detergent
