At present, most vehicle GPS on the market is powered by a built-in lithium battery, this power supply method is suitable for many portable digital products. Lithium-ion batteries have the advantages of stable discharge performance, high energy density, small size, and no memory effect.
Many users are accustomed to plugging in the GPS charger when using vehicle GPS, the car’s power supply will automatically charge the GPS batteries, so each time the GPS system is turned on or off is equivalent to charging and discharging the batteries, which will affect the battery life.
Since the main factor that affects the life and capacity of lithium batteries is the number of times the battery is charged and discharged, that’s why the GPS battery in vehicles has become less durable.
The correct use method is to charge the battery when the GPS power is low, and then disconnect the charger after the GPS is fully charged. It should be noted that the GPS battery would be at an over-discharged state by its self-discharge characteristics in case the GPS is not used for a long time. In order to prevent over-discharge, the GPS battery should be charged periodically every month.
The battery capacity of the newly purchased GPS is only 50% or lower, and it can be used normally for the first time. When the battery capacity is insufficient, it should be charged normally according to the instructions of the manual. It is best to use the original charger for charging.
In addition, there are several points to be noted during the use of GPS:
- Don’t over-charge and over-discharge the GPS battery. Charging normally when the battery capacity is low, which will not damage the lithium battery.
- Use the original charger for charging, don’t use a third-party charger.
- Most car GPS lithium batteries are built-in, don’t disassemble or modify the battery without permission.
- Avoid exposing the product to extreme environments and protect the battery from liquid corrosion.
In fact, the reasonable and correct use of lithium batteries, and proper maintenance, vehicle GPS service life will be extended according to the battery life.
