Popular Science | FAQ Battery for Walkie-Talkie

Many people will encounter battery problems in the process of using walkie-talkies. For example, what are the manifestations of the aging of the walkie-talkie battery? What to pay attention to when charging the battery....... Regarding the common problems of walkie-talkie batteries, let us understand the common sense of walkie-talkie batteries one by one:

1. At present, the battery of models with 3W and below is a single-cell battery (3.7V); the battery of models above 3W is a double-cell battery (7.4V).

2. Battery charging process: As the battery voltage rises, the charging current gradually decreases (the charging time cannot be calculated by the charger current alone. Among them, the maximum charging power of 500mA AC adapter is about 400mA; the maximum charging power of 1A AC adapter is about 800mA; The maximum charging power of 1.5A AC adapter is about 1.3A.

3. Battery aging phenomenon: the single charging time is significantly shorter; the single charging time is shorter; the power display/broadcast becomes very inaccurate; the battery is swollen.

4. Battery capacity: The battery capacity of the same electrolytic material depends on the volume of the battery cell.

5. Battery capacity difference: There will be a 100mAh operation difference in the battery capacity of the same model, which can cause a difference of 5 hours in standby time of the machine.

6. Due to the difference in signal strength of public network products, the standby current will be affected, which will increase the difference in the standby time of the same battery.

7. The charge/discharge capacity of the same battery (the duration of a single charge) is greatly affected by temperature (especially at low temperatures). The rated capacity of the battery is the result of testing under an environment of 23±2°C (0.2 times the battery capacity current).

8. The charge/discharge capacity of the same battery is greatly affected by the current, the larger the current, the smaller the discharge capacity. For example, a 1800 mA battery can discharge 1900 mAh with standby current, but it can only discharge 1800 mAh or even lower when discharged with emission current.

9. The impact of improper operation and use on the battery:

(1) Falling, bumping, pressing: it may cause internal cables, components to fall off and damage or even battery cores to crack and catch fire;

(2) Water ingress, long-term use in a humid environment: it may cause corrosion and damage to the battery contacts and protective plate;

(3) Long-term plugging in the charger or frequent plugging and unplugging of the AC adapter, etc.: it may cause the device to burn out or the battery to overcharge and bulge;

(4) Frequent short-circuiting of the charging contacts on the battery during use: it may cause damage to the device and failure of protection;

(5) The static electricity during use may cause damage to the device (directly reach the protection board through the charging contact piece);

(6) Unstable city power may burn out the charger;

(7) Using an unmatched charger may burn the battery;

(8) Frequent use of the battery until it automatically shuts down or has been plugged into the cradle will shorten the battery life.
