@miltmaster3: Yes, I've always had plenty of warning of my 520 battery going flat, but I've found that a good thing - can finish the current ride and then put on charge. The problem is that the time between charges is getting lower and lower. Hence the need for a new battery.


@pdlpsher1: Thanks for that. Only trouble is that battery vendor doesn't ship to NZ and the shipping for the green pry bars is USD18 vs a price of USD3.49! Still nothing I probably can't fix by digging around in the bay. Was just hoping someone might have tried a particular battery vendor with success (long bat life).

Cheers

Did you try searching for the same product from a seller located in China? These are commodity items and all the sellers sell the same thing. Just search by the battery part number.

I did go ahead and replace the battery in my 520. I got the battery from batteryupgrade.co.uk for £21.49 and I bought a metal and plastic spudger (great word) set from ebay for £2.89.

Having watched a youtube video I went ahead and pried off the front screen. It is glued firmly in place but if you work round the edge methodically, it eventually comes off although some force is needed. Take care at the bottom RH corner where the ribbon cable lives.

Next, unscrew the circuit board and lift it out. Unplug the battery from the circuit board. The battery is stuck to the case but can be easily pried out.

I cut the wires from battery to speaker then soldered the speaker wires to the new battery. The new battery came with the necessary plug and wires. The old battery is 700mAh but the new one is rated as 600 mAh.
Image

After this I reassembled. The Garmin started up fine but... no sound. I opened it up again and found the plug was slightly loose. Reassembled and all was good with those familiar beeps. To replace the screen I put a little bit of 'No More Nails' DIY glue round the edge and put a weight on the thing till the glue set.

It will be interesting to see how the battery life is from now on.

nice job! its a shame that Garmin is using a one-time foam seal. the one in my Edge 810 has a silicone reuseable seal.

i also noticed that there's no second circuit board for the speaker like on the 810...which is why you probably have to splice the wires with the battery.

As I had the problem with the display being slowly defective (the edge started to "fade out") Garmin offered me a 50% discount on the battery replacement if I wanted to have this done beside the replacement of the display. Actually I received a refurbished Edge 820. I paid US$64 for the display and battery replacement.

Bonus for me was that I received a refurbished Edge 820 which was way newer than mine (I bought mine almost after the release). Everything is going much faster.
But hopefully my old Edge 820 will not be repaired and sent to a Garmin customer as refurbished.
