Any NiMH battery can be charged

Post by asprin624 » Sat Jan 04, 2020 4:55 pm

If you remove the Garmin Batteries you will see it has 2 plastic holders between the 2 batteries.

Now if you look into the battery area of the GPSMAP 66S you will see a trip switch at the bottom.

If you put a plastic block between any 2 NiMH batteries it will press down on the switch and you then can recharge them the same way as the Garmin NiMH batteries.

You will have to make the correct size plastic block for it to work.

The blister-pack material most microSD cards are shipped/sold in seems to work well for this application.

If you have access to a 3D-Printer you also can print a nice part for this purpose.

See here (german only, but photo explain all you need)

Works great since months
Just waiting for a new firmware, to get the softwarebugs resolved

Hardware is fine

I'm normally fairly observant about these things, but I never noticed that switch!

Does a Garmin battery pack charge whenever USB power is applied ?

Yes, if the charging controller deems it necessary.
