Garmin Edge 305 external battery option

Anyone using an external battery to supplement the internat battery on long rides. If I understand correctly something like the Energi To Go battery can be used? I was wondering what the experience has been, how much it extends the usage of the battery, etc.

Also, I purchased mine used and it only came with the USB cable. Does the A/C charger do any better charging to maximum capacity?

I purchased a refurbished unit that had not been used. I have not tested it on a ride longer than two hours. Since it does not have a battery level indicator I have no way of knowing the capacity but it does not seem like it will last as long as advertised.

I used an external battery on my Garmon 705 this weekend. It worked very well.
The battery I used contains two NiMH AA batteries which allowed me to carry 2 AA alkalines as backup. The backup was not needed so I think, for me, the Duracell Li-Ion battery will be a better choice because it is much more compact. http://www.duracelldirect.com/dr7000li.aspx


Are you sure you have no battery level indicator? On my 705 I believe it appears as an icon when I select "menu".

It does have a battery indicator. Upper left corner on any screen. You need to wait for a second before it shows up. 4 Bars.
