As Steve says, fly. If you really need to charge it on the ground, you need to put a battery charger on your aircraft battery and turn on SkyView. SkyView needs to see a main power bus above 12.25V to charge. There's no way to charge the battery by itself.

I have an aft battery, with no access to the terminals, so I installed a 7 A charging port. This is not enough to power up the panel, charge the main battery and charge the SV battery. Consequently, I installed a separate 5A ground power plug, just for the SV.

Flying may be the best way to charge the SV backup battery but not the safest. I use a battery charger after doing the annual backup battery check. At our hanger crawl last March I connected a battery charger and left the main power switch and SV on so that it could be viewed. I pulled the breaker (VP-X) on everything else.
