How to Determine Which Batteries to Use in Your GPS Receiver

A GPS receiver is a regular fixture in cars today, displaying location, time of day, speed, and distance traveled, But it runs on batteries, which in some GPS models can drain in just a matter of hours, especially if you're on a road-trip vacation. Battery types vary depending on model and settings. To determine which batteries to use in your own GPS receiver, follow the steps below.

Difficulty: Easy

Instructions

1. Consider the amount of time you're on the road and how often you use your GPS receiver. The more you use the receiver, the longer-life battery you'll need.

2. Choose from lithium, NiCad, alkaline or other kinds of batteries. There are several pros and cons for each, so check on the similarities and differences of each type of battery.

3. Ask other car owners with GPS receivers what kind of batteries they use. Most will know how well a certain kind of GPS battery works, based on their experience.

4. After deciding on what kind of GPS receiver battery to purchase, price-check at different stores before buying. You can also search online for batteries available online, but buy only from credible online vendors and stay away from off-brands.

5. If you decide to buy rechargeable alkaline batteries, bear in mind they require a special charger, and factor that into the price.

Tips & Warnings

• Buy an external power adapter for a GPS receiver that runs off your car's cigarette lighter, and keep it in the car at all times. It will come in handy if your batteries die out while on the road.
