If you experience the problem which is The battery doesn’t be charged when power level is above 95% with AC adapter connected. This is a normal condition for battery protection, not a problem for either the battery itself or the charging function. When the battery is charged to 100%, it will stop being charged.
If you have a battery charged but no cranking power, another reason behind it could be a loose connection between the battery and the battery terminals. The terminals can also get corroded with time and result in a bad connection. To check if the battery has a good connection with the terminals, you can perform a quick load test with a multimeter.
But if the worst comes to pass and your battery discharges completely, it won’t respond when you connect a charger, at least not initially. The amp meter stay at 0 amps (or near it). However, after fifteen minutes, the amp meter will gradually rise, showing that your battery has started accepting the charge. 2). Loose Connection
You can unplug and re-connect the AC adapter several times to resume charging to 100%. If you experience the problem which is The battery stop being charged after the battery level is charged to 60% or 80%. Please make sure whether you set up Battery Care Mode in MyASUS (for some models, the Battery Health Charging is a separate app).
Poor contact between the rectifier and load can produce zero amps even though the voltage is present. Some people dismiss the possibility of a bad battery because the charger shows a voltage. However, a defective battery can still show a decent voltage on the display. The voltage doesn’t mean your battery is healthy.
The amperage on the meter will rise when the charging process starts. It may stay at zero when the battery is fully discharged. But eventually, the readings will increase. However, the amps will gradually fall as the charging process approaches the final stage. The amps hit zero once the battery is fully charged. 4). Dead Battery

3 Ways to Fix a Laptop That Is Not Charging
Inspect the power adapter. Examine the entire length of the power cord for tears, dents, and worn-down insulation. If you notice any flaws, or if the power brick is warped or smells like burnt plastic, the cord is probably faulty. Try bringing the laptop to a local repair shop and ask to try one of their working power adapters.

How to limit current when charging from alternator
To summarise: each individual setup has a different resistance (depending on the kind of battery used, the wiring, etc.) and each individual setup has a different voltage difference (depending on the alternator model, etc), and Ohm''s law tells us that these factors determine how much current is drawn. Therefore, provided your alternator is ...
