What types of batteries are best for extended GPS use?

Choosing the Right Battery

When selecting a battery for extended GPS use, consider the capacity, self-discharge rate, and chemistry of the battery. A higher capacity battery will provide more power and longer runtime, but it may also be larger and heavier. Look for batteries with a capacity of at least 3000mAh, as this will provide several days of runtime for most GPS devices. Self-discharge rate is also important, as it determines how quickly the battery loses its charge when not in use. A lower self-discharge rate is desirable, as it will help the battery retain its charge over a longer period.

Battery Chemistry

Lithium-ion polymer (LiPo) and lithium-iron phosphate (LiFePo4) batteries are popular choices for extended GPS use. LiPo batteries have a high energy density and a relatively low self-discharge rate, making them well-suited for long-term applications. LiFePo4 batteries, on the other hand, have a longer lifespan and are more resistant to high temperatures and overcharging. Both types of batteries are suitable for GPS devices, but LiFePo4 batteries may be a better choice for devices that require a high level of reliability and long-term performance.

Additional Considerations

When choosing a battery for extended GPS use, also consider the size and weight of the battery. A larger battery may provide more power, but it may also be heavier and more cumbersome to carry. Look for batteries that are specifically designed for GPS devices, as these will be optimized for the device’s power requirements and will provide a longer runtime. Additionally, consider the battery’s charging voltage and current rating, as these will determine how quickly the battery can be charged and how much power it can deliver to the GPS device.
