Rechargeable batteries for your GPS

For some time now, I’ve been wanting to research and blog about choosing recharegable batteries for your GPS receiver. This is one of the few topics I regret not covering in my book, GPS Mapping: Make Your Own Maps. I didn’t have to look far to research the subject. I turned to one of my favorite GPS/mapping software discussion boards and found this thread. The idea of being able to recharge batteries in only 15 minutes was quite enticing, so I went out and bought the suggested unit, a 15-minute charger from Energizer (Amazon link), which comes with 4 AA batteries. I got mine at Target, but as you can see from the link, Target is also selling them through Amazon.

I did a quick test with my GPS, a Garmin GPSMap 60CS (Amazon). Granted, it wasn’t the most scientific test, but I was pleased to get 20 hours out of two batteries, which is exactly what the unit is rated. I’m quite excited, since all four of my GPS receivers use AA batteries, as does my digital camera.
