Charging at 2 amps describes how fast it is charging. The amount of charge is the current times the time, so after 5hours at 2 amps it has taken a charge of 10 amp-hours.
yes it just takes longer to charge, but check how much Amps (A) your charger gives out and how much Amps your battery can take if the battery has lower Amperage (A), don't do it, otherwise you're fine. <<>> No, the charging unit has to have a higher output that the battery voltage that it is charging. For example, on a 12 volt car battery the charging rate is 13.5 volts.
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.
if the capacitor is not initially charged then it will receive during its charging an electric charge Q given by Q=V/C=16/8.8 = 1.82 microcoulomb
You need to have a 7.2 or higher battery charger
The charging time will depend on how much of a charge was left in the battery and on the charger you use to charge the battery. The more energy you have to put back in it, the longer it will take for a given charger. And some chargers will be able to deliver more current than others. This will result in a higher charging rate, and a lower elapsed time for the charging cycle.
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.
reset battery no charge light after battery replacement.
The battery is probably dead.
You simply cannot as it is THE battery that you are charging...
How long should I leave a battery on charge
No, the charge in the battery is a change in state of the battery contents, not an addition to the battery.
It has to do with your battery charge. it's either charging or is at full charge.
Rechargeable batteries are generally stored and shipped with no charge. This allows for a longer battery life. Fully charging the battery the first time will give you the best results for maximum charge and battery life.
Can You Charge...Yes. As a matter of fact, in order to charge a battery, the charging voltage HAS to be greater than the charged battery's voltage or no current will flow and charging cannot happen.Of course, the charging voltage cannot be excessive, or damage to the battery being charged will result.In your question, 4.6 volts is not excessive for a 4.2 volt battery.
Yes. Top up battery with clean water after charging only. Never top it up before beginning a charge.
Answer 1: yes Answer 2: How can it be discharging if it is charging?
It depends on the charging rate available.
