Love My Lithiums!

We're ready for another season caching the Huron Metroparks! My lithiums are in!

 

I almost gave up GPSr Geocaching as my units (Garmin Oregon 450T and Magellan Explorist GC) just ate batteries. Then I invested in lithiums: Energizer AA Ultimate Lithiums. Instead of replacing Alkalines every 1.5 outings, I would go many, many excursions before needing to replace them.

Good to know:

• They hold power up to 20 years (in storage) and perform in extreme temperatures [-40° to 140°F]
• They do cost more, but I really feel that overall I saved money as I wasn't changing them as often.
• If you are concerned about expense, go ahead and use your Alkalines or rechargeables. Just make sure you keep an extra set of lithiums in case of emergency. The power doesn't drain over time (so they are fully charged if/when you need them) and are life saving when dealing with a -26° Michigan Winter.
• How to store them? Mentioned in an earlier post about performs. Lightweight, sturdy and waterproof. I store mine in pairs.
• When you do use them, remember to go into your GPSr unit's setting and change the battery type for optimal performance.
• What's the difference between Energizer Ultimate and Advanced Lithiums? Ultimate lasts longer and are more powerful. Ultimates are recommended for GPSr units per the Energizer site and packaging.

Now, I'm not the expert and end-all-be-all, but I know these work for me. Give it a try and see if you notice a difference.
