Depends on the charging current.
A general guideline is that you overshoot with around 1.4 times the capacity when you charge, so if your charge current is 1 amp, you need to charge for a little more than 4 hours for a full charge. If charge current is 0.5 amps you need about eight and a half hours for a full charge.
These are two common ways battery capacity is measured. Wh stands for "Watt hours", and it's a measure of the actual energy content of the battery; it measures how much power (watts) the battery can supply multiplied by the number of hours it can do so before it runs out. Most batteries are labeled with a capacity in mAh (milliampere hours). This is a measure of the electric current the battery can supply multiplied by the number of hours it can do so. Example: if a battery is labeled 3000 mAh, it should be able to supply 3000 mA of current for one hour, 1500 mA of current for 2 hours, etc. You can figure out the Watt hours for a battery by multiplying the voltage of the battery by the amp hours (amp hours = millamp hours / 1000).
The milli-amp-hours rating has nothing to do with the voltage. The rating should be something like 3000 mah at 12V or 3000 mah at 1.5V. One common 3000 mAh battery is 3.0 volts; another is 3.7 volts. A common camcorder battery is 7.4 volts. Some DeWalt tools use 12 V 3000 mAh batteries.
The runtime of a 3000-watt inverter on a 12-volt battery depends on the capacity of the battery, measured in amp-hours (Ah). To calculate, first convert watts to amps using the formula: Amps = Watts / Volts. For a 3000-watt inverter at 12 volts, it draws 250 amps. If you have a 100 Ah battery, for example, it would run for about 0.4 hours (24 minutes) under ideal conditions, not accounting for efficiency losses or the battery's discharge limits.
go to gamestop and ask them if they have a psp 3000 battery if not then shop online.
3000 hours = 0.342 years.
multiply 50 by 60 because 50 hours you said and 60 minutes in a hour. That will give you 3000.
This is an unanswerable question as neither the size of the battery nor the amount of electricity drain is given. a 3000 milliamphour battery will last 10 hours if drained at 300 mA, but a hundred hours at 30 mA.
Which does the trouble belong to? Is it your Acer Aspire 3000 laptop? Or is your laptop Acer Aspire 3000 battery hot? .
2 years = 104 weeks 3000 hours divide by 104 = 28.846153
You need 3000 x 24 watt-hours or 72,000 watt-hours. A typical car battery has a capacity of 50 Ah or 600 watt-hours, so you would need 120 car batteries, connected in the right combination of series and parallel to give the right voltage for the inverter.
You can't, even with the battery.
