The overall service life of rechargeable portable lamps depends not only on the quality of product hardware, but also on

the maintenance of daily details. Most equipment aging, failure, and battery life attenuation problems all stem from long-

term neglect of subtle maintenance. In order to maintain the long-term stable life of lamps and prolong the service cycle

of the whole machine, the following fine maintenance work that is easy to be ignored should be done well.

First, check the charging interface regularly to prevent wet oxidation damage.

Portable lamps are mostly used in outdoor, humid and dusty environments, and the charging interface is exposed for a long

time, which is easy to accumulate dust and water vapor, resulting in oxidation of metal contacts, poor contact, slow charging,

inability to charge, short circuit of interfaces and other problems. It is recommended to check the state of charging interface

regularly every month and clean up dust and impurities in time; After being used in rainy days, dew and humid environment,

the equipment should be fully dried in a ventilated place to ensure that the interface is completely dry before being stored,

so as to avoid water vapor residue from corroding the circuit.

Second, standardize the charging and discharging habits and protect the activity of lithium batteries

Lithium batteries are most afraid of deep power loss. Long-term use-up and recharging will lead to battery activity attenuation

and capacity shrinkage, which will greatly shorten the service life of the battery. For daily use, it is recommended to maintain

the power in a healthy range of 30%-80%, try to avoid completely discharging the power and recharging it, and stabilize the

battery energy storage performance through scientific shallow charging and shallow discharging, so as to maintain the

endurance of lamps for a long time.

Third, it is necessary to separate the battery when it is idle for a long time to prevent the circuit from aging due to moisture.

When the lamps are left idle for a long time, if the battery is connected to the fuselage for a long time, moist air will easily enter

the equipment through the interface and gap, which will lead to wet oxidation of the circuit board, micro-short circuit and

standby leakage, resulting in silent power consumption and malfunction of the equipment. When the battery is not used for a

long time, it is recommended to take it out and store it separately, keep the fuselage dry and ventilated, reduce the standby loss

and the probability of circuit damp failure from the root cause, and ensure the equipment to be in good condition next time.

summary

The durability of rechargeable portable lamps depends on the maintenance of daily details. Doing a good job of three-point

basic maintenance, such as moistureproof interface, standardized charging and discharging, and idle power-off storage, can

effectively avoid most failures, greatly improve the stability and service life of equipment, and achieve long-term peace of

mind and durability.
