Your Garmin help, please

when this Edge 800 finally dies (internal battery becomes more shit)

I've replaced the battery in my Edge 705 once so far. It was only £10 or so on eBay and gave it whole new lease of life. Back to running for ~12 hours on a single charge (I should be able to get away with just a single 5000mAh USB battery pack for the upcoming 24.)

Garmin do it because ~99% of the use cases are covered by the battery life of an internal Li-Ion battery:-

• Promuters (STRAVA ALL THE COMMUTES!)
  
• SportiveWankers (It will be happy up to 10 hours)
  
• Beardy Audax Weardies (well, up to 200km anyway)
  
• Cycling holidays with overnight hotel stays (access to mains charging)
  
  

For those that want to go a bit further Garmin have the (horribly overpriced) cache battery.

And the first thing most people do when returning from a ride is plug it in to the computer to upload to Strava and so the charge is topped up as a handy consequence and not an explicit action.

Ironically, the new 'upload via bluetooth/wifi' feature of the later Edge Series will mean people are less likely to need to remove the GPS (depends where they store the bike though) and Garmin might start to need to think about a battery powered version for cycling.

The USB lights do work for people who have to take their lights off whenever they park the bike, you just get into a routine of bringing them in and plugging them in to keep them charged up. I don't so I've got a bolted on dynohub light on the commuter.
