What do you mean 'weak'?
Remember that ALL rechargeable batteries (NiCd and NiMH) start out at only 1.2 volts when Alkaline batteries start out at 1.5 volts. Don't Garmin stick a battery type option in their eTrex models to better manage the power expectation/consumption?
To make them last the longest, just buy the highest capacity Metal Hydride (NiMH) batteries you can find - at least 2200 mAh for AA and 1000 mAh for AAA and then charge them using a NiMH-optimised charger.
(To the best of my knowledge it's a limitation placed by the chemical nature of the battery and the metals used therein). That's why mobile phones with their Lithium-Ion batteries are typically 3.7 volt - it's a different chemistry again.
