Garmin Edge 305 battery replacement

Below is a preview, click to read the full post

I noticed that the battery life on my Garmin Edge 305 had (over the last three years) dropped to about 6 hours from the 12 hour typical battery life that it is meant to have when new. 6 hours is not enough for a 100km enduro race or a 24 hour race.

Where to buy Battery?

I'm looking at buying the all new 7 UP Trout Light http://www.troutie.com/index.php?option=com_cont... but they can no longer ship matching Li-ion or Polymer batteries to Australia due to air freight import restrictions. So can anyone recommend where I could purchase a 14.8v 5.2Ah bottle battery other than Lupine please? I don't have time nor have the inclination to build one either.

Thnx - Winco

Recycled Batteries

Below is a preview, click to read the full post

Two packs made from old (well - they were physically old but never used, so the cells should be in good shape) laptop batteries.

Not for the feint of heart... harvest the cells (by ripping the laptop pack apart while trying not to short it out!) and solder together. The larger of the packs is made from two 'slabs' of 2S2P (2 cells in series connected in parallel) cells that are rather convenient to use because only one wire connecting the 2 'slabs' was required.
