Garmin back-up battery
Postby djw47 » Tue Nov 29, 2016 1:21 pm
Has anybody successfully attached one of those phone backup power packs to a Garmin and had it charge while recording a ride? Any suggestions on a good place to buy a backup power supply that won't cost a fortune (like the official Garmin one)?

Things to check are backlight, smart record (not 1sec, unless you need that) and possibly using only GPS and not GLONAS as well.
The only problem you might come across is once you unplug the charger it may trigger an auto shutdown timer. I'll have to do a quick test now.

I've had three garmins, a 800, and two 810's and they have all had excellent battery life even after a lot of use.
I think Garmin have a refurb service which could be worth considering.

Not all devices work off these back up batteries but the Garmin should. I am using this one from office works to power a bike camera I am trialing and should get a min of six hours use.Yet it will not run my Sony action cam.
You can get larger capacity for only a few more dollars but I like the rubberised edging of this one for bike use. It comes with a short Micro usb cable. some things require a Mini usb cable but they are easy to get as well.

Yes, good point. With mine mounted on the stem I had to buy a right-angled USB plug.kb wrote:You might want to check that you can physically fit a plug in while the Garmin is mounted too. Some combinations don't leave enough room.

Fascinating.. I've never bothered with that stuff but there you go.djw47 wrote:So, for future reference, I discovered that if I disable all Strava Live segments on the Garmin, the battery life improves enormously. Now draining at a much more acceptable 5% per hour with GPS and Glonass enabled.
Do you think it could be due to the device switching the backlight on for notifications or the processing required?

Or possibly just that the Bluetooth chip is powered up for a much greater proportion of the time to handle the data transfers. Particularly as it uses the higher power BT 2.0, rather than the low energy BT 4.0.Comedian wrote:Fascinating..

Correct, it doesn't use Bluetooth. The Garmin downloads the routes and must be constantly checking live GPS co-ordinates against those stored for the routes which I assume uses a heap of additional processing power. I have always kept BT switched off unless I am using it at the end of my ride to transfer data to my phone.Discodan wrote:I believe the Garmin doesn't communicate with the phone when it's doing live segments so wouldn't be consuming bluetooth power. The segment details are synced to the device and it's measuring you against your PB or someone you follow from the last sync
