Battery Pack for Garmin Oregon GPS

I have the battery in my Garmin 650T in use.
He is, as in the description, easy to handle, since both cells (a little relative to each other, for better insertion) are interconnected.
Likewise, the battery can now be loaded via the USB cable to the PC, or with the power supply unit in Garmin GPS.
It eliminates the annoying definitely out fingers of batteries.

Disadvantage:
-low capacity as a single AA cell. (Garmin: 2000mAh AA there to 2700mAh).
-Please Note, there are definitely Ni-MH cells, and no Lithion ion cells how to read in a variety of descriptions on the net!

Overall, however, strong buy recommendation. I give "only" 3 stars because even I thought it would be lithium-ion technology with higher capacity.
