Battery charging problem

You don't indicate in the description the age of your UPS, but if it is more than 4-5 years then it is likely time for replacement.

Batteries have electronics data that software has to get to properly charge it. Newer lithium batteries maybe different. But apparently, you have a work around for a lengthy use of the new battery.

The battery may not be charged to full capacity. Does the battery show full charge when you charge it for 12 hours?
The adapter may be faulty. Check the battery indicator on the phone when it is being charged.

The adapter is working correctly. The battery is either slow to charge or in need of replacement.

It's possible your battery isn't charging at all so to test this boot into bios -> battery status and watch it run overnight.

I had the same problem, I removed the bettery while it was still plugged in, tested it, then plugged it back and and now all is fine.

Ensure that you are properly recharging the battery.

1. Insert the small end of the adapter into the external extension connector (labeled "5.2V=IN") on the back of the Nintendo DS Lite, just next to the SLOT 1 Game Card opening.

2. Swing the prongs on the AC adapter until they lock into place, then insert it into a standard (120 volt) outlet.

The plug should be mounted vertically or on a floor outlet (such as a power strip).

3. Once the adapter is properly inserted, the unit will begin to charge (the orange charging light will display).

4. Once the DS Lite is fully charged, the orange charge light will go off.

Check the AC Adapter for damage (such as bent prongs or split wires). If you see damage to the AC Adapter, purchase a replacement from Nintendos Online Store.

Try plugging the AC Adapter into another wall outlet. Its possible the outlet is not working properly and has not been charging the Nintendo DS Lite.

If you are unable to get power to your Nintendo DS Lite, despite trying to properly recharge the unit, then your system will need to be repaired.

Nintendo offers convenient repairs, fast turnaround times and, for all systems repaired, a new one-year manufacturer's warranty.
