AA battery life for Garmin GPS's which is best?
A large percentage of trail riders that use Garmin GPS's power their GPS units from AA batteries. My 12 volt DC, GPS hard wired power source failed in south Laos after some deep water crossing (DC voltage converter box from 12 volt DC to 5.5 volt DC water logged) and was forced to use AA batteries.
I've been trying different brands and types that are available in Thailand. The cheap AA batteries, obviously depending on the GPS units power setting for brightness and sleep time, tend to last about 4 hours, top end expensive can last up to 2 days of riding.
My current favorite is the Panasonic Evolta, these i've been getting up to 2 days of use. Tried the Tesco "Power High Tech", only got about 4 hours, won't be buying those again.
Currently trying the Energizer Advanced to see how they perform.
