I've been doing some shopping at a couple of my favorite expedition suppliers - Lowe's hardware and Walmart - and noticed that they had some great deals on batteries. I haven't taken time to compare prices but both stores were had some pretty good values. I guess this is all a pre-christmas deal - plenty of low cost double A batteries to power those new tools and toys.
I know I go through more batteries than I like each year on Spartina. There are lots of pieces of gear that required double A and triple A batteries. Above you'll see flashlights, emergency strobes, anchor light, a vhf radio, gps and SPOT. It would be nice to think I could be "green" and use rechargeable batteries but in my experience the technology isn't quite there yet. Someday I hope to add a solar panel to Spartina to I can be a little bit more green. But for now I need batteries.
I've tried to standardize with all aa batteries, but the only ICOM radio I could find last year to replace my old one took aaa batteries.
The strobe, flashlight and anchor lights use double A. SPOT uses the lithium double A. And I heard from the crew of Dawn Patrol last year that my gps would do better if I use the lithium batteries (the standard double A last just a little more than a day with that bright color screen).
So sometime before the christmas season is over, while the double A batteries are going for as low as 40 cents each, I'll pick up on of the 36 battery packs. I know I'll make good use of it next year.
