Life of batteries

Hi all, I always get nervous  about the condition of the batteries in my Garmin Etrex. I'm really bad at checking these kind of things.
So I thought, maybe I'll just get some batteries that have a really long life and I won't have to worry about them for a long while.

10 years isn't bad


Then I found these


They should keep me out of trouble.


Have you seen any batteries with a longer life than these?

Yes Slim. Energizer Ultimate Lithium AA, hold power up to 20 years, but leaving batteries in any electrical device for prolonged periods of time without use, could cause battery leakage to terminals destroying what ever battery operated guismo you've got.

For a lot of us, choosing disposables batteries can be a bit of a dilemma, particularly when they are for such an essential device as our GPS.

Choice has done a review (April 2016) of disposable AA batteries. In this review, the Energiser Ultimate Lithium AA batteries were the number 1 recommendation with the Kogan Lithium AA batteries coming a fairly close second. The Kogans are better value for money than the Energises.

The Choice testing protocol can be found here:

Sadly, Slim, the Energiser eco advanced batteries weren’t recommended and came way down on their list!

Regardless of what brand of battery that we choose, I believe that it is essential to carry spare sets for the GPS and two way.

Another option.......carry a small 6 volt rechargeable battery in your backpack which (with a bit of "fiddling") you can connect direct to your "gismo" (via a male/female plug setup) if it is
6v or if it is 3v gear it down.


Be lucky.

I just use rechargeables in the e-trex,you can select the type your using in the menu.I keep a few spares charged up as well.I'm currently using Ni-Mh 3Ah.

I used to use Rechargeable 1.5 v batts Deutran but they only put out 1.2 v, they also had a shorter duration .........maybe things have changed ?

The e-trex is designed for different battery voltage when the type is selected.The life of the ones I use are 3Ah. Energizer Lithium 2.8Ah.
