Generally portable a/c units are not recharged because they do not contain a service port like a home or auto a/c unit does. At the factory they charge the unit crimp the tube then weld it closed. And no one can service freon unless then can vacuum recover it.

All rechargeable batteries die if left to sit uncharged for extended periods of time. If you can replace the battery, do so.

your unit may be have possible leak on piping then refrigerant exit or had leakage of refigerant try to locate leak then braze it then recharge a correct amoun of refrigeran. if you use heater try to check heating element if ok by supplying voltage or used ommeter to test continuity.

Check the thermostat. That could be the whole problem. Otherwise, you may need to have it recharged or serviced.

clean the condensing unit and check the freon gas,if not enough gas recharge it

I am not sure, i have a similiar unit that is brand new, seems like a faulty mechanism from the maker, it starts cold for about 2-3 minutes and then shuts down condenser and blows hot air repeating this cycle. I don't believe it ias a recharge, just a faulty machine

It has to be done by licensed technician. Gas must be reclaimed and requires a special set-up with gauges to measure amount going back in.

Assuming the filter is clean then you may have to open it up and clean both the condenser coil and the expansion coil, they are probably dirty. It is a job you'll want to do outside with a garden hose. The pressure you use is a matter of experience so you don't use to much force from the hose and bend the fins on the coils. The coils need this cleaning done from time to time as it is just part of normal care.
No recharging is needed as the system is sealed and should never leak, contains no high pressure refrigerant hoses that can leak with age as does automotive air conditioning, yes our cars are made different because a lot of flexing and moving of said parts occur with an automobile.
