The charging current of a battery refers to the amount of electric current supplied to the battery during the charging process. It is typically measured in amperes (A) and is crucial for efficiently replenishing the battery's stored energy. The charging current must be appropriate for the battery's specifications to prevent overheating or damage, and it can vary based on the battery type, capacity, and state of charge. Proper management of the charging current is essential for optimizing battery lifespan and performance.
The different charging processes include constant-current charging, constant-voltage charging, and trickle charging. Constant-current charging delivers a consistent current to the battery until a certain voltage is reached, then switches to constant-voltage charging to prevent overcharging. Trickle charging is a slow, low-level charge that helps maintain a battery's full capacity over time.
If you are recharging a battery you will need to input more power than you could draw from the battery after charging, as the charging process is not 100% efficient. Most of this excess power will be lost as heat during charging.
No, not unless it has a voltage or current regulator or series resistance to limit the current (built in somewhere).
may be its around [5v;800ma]...

Boost charging involves a high current for short period of time to charge the battery. It is generally if the battery has been discharged heavily. Boost charge enables the quick charging of depleted batteries.
NO, a 12 volt battery cannot be charged with a 6 volt charger. To charge any battery, the charging voltage has to be, at least, slightly higher than higher than the voltage of the battery. Current flowing through the battery is what accomplishes the charging, and no current will flow at or below the voltage of the battery to be charged.
As long as the laptop is plugged in already, and 'charging' the battery, yes. I often remove the battery and start charging another one while in use.
There is not enough information. It depends on the type of battery: chemistry, cells, size.
It's in the amount of current that is used to charge the battery. If the amp-hour (Ah) capacity of the battery is known, charging at the 5-hour rate or quicker would count as a boost charge, while charging at the 20-hour rate or slower would be a trickle charge. So for a 40 Ah battery, a boost charge is more than 8 amps while a trickle charge is less than 2 amps. A normal charge would be 4 amps.
That would also depend on battery chemistry.
The gauge on a battery charger typically displays the charging status or the voltage level of the battery. It may indicate whether the battery is charging, fully charged, or if there are any issues with the battery. Some chargers also show the current flow or amperage being supplied to the battery during charging. This information helps users monitor the health and readiness of their batteries.
