My battery is not charging, icon shows no movement at 23% since yesterday and it is not in use since charging

Need a little more info. To charge a battery and this goes for all batteries you must have a higher input voltage than what the batt. Is rated. For example a car battery is rated at twelve volts. To charge your battery the alternator applies about 13.4volts. So if you charger is under voltage it won't charge past the equal amount of charge in the battery. Take your charger to just about anyone with a volt meter and have the output voltage checked. Batteries Plus, auto parts store computer store, best buy geek squad in store should be able to help. Good luck, Bret
