How long will a 30Ah battery last with a 850mA per hour draw?
To calculate how long a 30Ah battery will last with an 850mA draw, you can use the formula: Battery life (hours) = Battery capacity (Ah) / Current draw (A). First, convert 850mA to Ah, which is 0.85Ah. Then, divide 30Ah by 0.85Ah, resulting in approximately 35.3 hours. Therefore, the battery will last around 35 hours under a continuous 850mA draw.
Can i charge a 12v 7.2 battery with an out 12v-300mA charger?
Yes, you can charge a 12V 7.2Ah battery with a 12V 300mA charger, but it may take a long time to fully charge the battery due to the lower current output. The charger will provide a safe voltage for the battery, but the charging time could be significantly extended compared to a charger with a higher current output. Ensure the charger is compatible with the battery chemistry to avoid any damage.
How long would an 8 Amp hr battery last with 75mA current draw?
An 8 Amp hr battery would last approximately 106.67 hours with a 75mA current draw. This is calculated by dividing the battery capacity (in Amp hours) by the current draw (in mA) and converting the result to hours.
How long does a 12v 7ah 20hr battery last?
Depends on the current draw of what you hook it up to. At a draw of 7 amps (80 watts) it'll last for one hour. At a draw of 1 amp(12 watts) it'll last for 7 hours, ASO.
How long should i charge my air soft battery its 8.4v and 1500mah and the charger has a output of 300mA i did the sum and it said about 7 and half hours is that right?
i would recommend a smart charger for your batteries
How long will a Battery of 7.4 Volts 700 Amp-Hour last?
The voltage doesn't enter into the issue.If the current draw of your battery-powered equipment is 1 Ampere, the battery will last 700 years.If your equipment draws 1/2 Ampere, the battery will last 1,400 hours.If your equipment draws 2 Amperes, the battery will last 350 hours.And so on.CorrectionA 700 AH battery will THEORETICALLY last 70 hours at 1 amp current draw. A 700 AH battery will THEORETICALLY last 140 hours at 1/2 amp current draw.A 700 AH battery will THEORETICALLY last 35 hours at 1/2 amp current draw.The theoretical capacity of a battery is always greater than the actual capacity; electrical energy is released in the form of heat inside the battery.
How long will a regular battery last?
a car battery last for about 3-5 years
How long does a 2200a h batery last?
The duration a 2200 Ah battery lasts depends on the load it's powering. For example, if the battery is discharging at a rate of 2200 amps, it would last for one hour. Conversely, if the load is lower, say 220 amps, the battery could last for 10 hours. To determine the exact duration, divide the battery capacity by the current draw in amps.
How long does a car battery last if the car is seldom used?
As long as the battery is kept charged then it should last 3-5 years.
How long does a Panasonic triple a battery last?
