Everyone should be taking Lithium

November 5, 2005

Everyone should be taking Lithium… Lithium batteries anyway. I have been using Energizer Lithium e2 batteries in my GPS, and in my limited testing I get 24-32 hours of opertational use from a single pair. This compares with around 7 hours with a pair of regular energizer batteries.

The e2 batteries cost much more than regular batteries, but the cost are pretty similar per hour of use and the e2 lithium batteries are much more convenient since I don’t need to change batteries nearly so often. The e2 batteries also weigh half as much as conventional batteries. That makes a big difference when you start carrying a dozen spare batteries. It is even better when you realize that you get the power of 36 regular energizer batteries with the weight of only 6.

My only note of caution, at least in my GPS. The batteries gauge reads completely full until maybe 40 minutes before the batteries die completely, so I always carry a spare set.

So take some lithium on your next trip.

  1. I’m guessing that the reason you don’t get a steady decreasing power indicator on your GPS is because of the flattened energy curve. It probably offers a nice, flat and consistent energy level, unlike traditional batteries, that have more of a curving downward arc. Hence, devices that check power via the current power output (e.g., most all of them) wouldn’t be able to get a good read on how much power is left. I’ll stop babbling now. =)

  2. no way man… rayovac 15 minute recharger system. recharges 2 AA batteries in 15 minutes and operates at 110V or 220V. highly recommended by the global reconnaissance organization. :)

    small tech dissertation here:
