Apparent charging system failure on 2012 dl650

I got a flat battery today for the second time in 3 months .
3 months ago I took my bike to a repair shop , The repair shop person told me I needed a new battery which has now gone flat too . fortunately the old one charged up just fine and has been running in a Honda for the last 3 months . I pulled my new battery out an put the old one back in looks to be working just fine.
The V-strom is my daily and clocks about 300 ks per week , Rain or shine . I suspect that the new battery will charge up just fine but go flat again in about 3 months .
I do not know if I have a short somewhere or a bad charging circuit .
Although I am a retired mechanic I have not worked on motor vehicles since the mid 90s . so at this stage I am looking for possibilities and where to check .
Battery is class mat type .

With the aid of a multi meter set to DC Volts, check (and record) the charging voltage across the battery at various rpm (idle / 3,000 / 5,000). Use the search facility and look for stator: https://www.stromtrooper.com/dl650a-...se-advise.html, https://www.stromtrooper.com/dl650a-...ends-trip.html

What if any aftermarket electrical accessories do you have on the bike?

Also, you may very well have a bad stator as they are currently under recall:

The fix is free but you will be out the time to get it to a dealer and back. Even if it's not bad now, get it replaced under the recall.

Active GPS mount usually contains voltage converter (12V to 5V). When connected directly to the battery, voltage converter will eventually drain it.
If this is your case and charging system on your bike is OK, I would suggest connecting GPS mount to a switched source - see "Aux Connector and Heated Grip Connector Location" sticky thread on this forum.

It is his daily driver and he does 300ks per week so it will not be the parasitic drain from the GPS mount. (0.02amps)

Lasting 3 months is a puzzle ?

Does it go flat when riding or parked ?

I would fit a volt meter and keep a close eye on the readings you get.

Have you had the stator replaced due to the recall?

This. Check the right side of the bike, above the oil cap, for a rubber wire sheath wrapped with a white or silver tag. Silver means the recall was done. White means the recall needs doing.

Being slow doesn't make a boring bike. I had a R1 which I thought was boring. Boring is a bike that doesn't speak to you. If you like what your bike is saying let it's voice take you to far flung places. - Vertical C

It is connected to a switched source ( professionally installed)
