How Long Will A 6 Amp Hour Battery Last
How Long Will A 6 Amp Hour Battery Last. This means that the battery will last 600 wh/1000w = 0.6 hours If you draw 2 ma for 5 hours, you have used 2 ma · 5 h = 10 mah.

The second row tells us the battery can power a 0.7 amp appliance for 5 hours. If you need more than 5 amps per hour you should consider having two or even more batteries. If you always taking it to 50% or even going beyond it from time to time then you will most likely be on the low end of the average,.
This Depends How Many Amps You Draw.
A 2c battery would need just half an hour to load 100 ah, while a 0.5c battery requires two hours. In other words, you can have “any time” as long as when you multiply it by the current, you get 10ah (the battery capacity). Or if delivering 10a, it would last for only 1 hour, or if delivering 5a, it would last only for 2 hours.
Almost All Deep Cycle Batteries Use The 20 Hour Rate.
By apc's own figures, this ups can run 300 watts worth of equipment for around four minutes. The calculator will calculate the battery life if the watt hour and the battery voltage is known. Wilhelm peukert, inventor of the peukert’s law formula.
After This Time It Will Have A Voltage 5.25 And A Capacity Of 4.0Ah.
After one hour of use, the battery will run out and need to be recharged. Say you have a 1800 mah battery, and you connect it to a 20 ma load: This is the industry average ’20 hour’ rating.
The Same Battery Discharged At 0.5C Provides 500Ma For Two Hours.
Larger chargers may be used to decrease charge time, but may decrease battery life. Using the 12v car kettle from before: That means a constant use of 5 amps an hour for 20 hours (5 x 20 =100).
After This Time It Will Have A Voltage Of 5.25 And Capacity Of 3.5 Ah.
If you always taking it to 50% or even going beyond it from time to time then you will most likely be on the low end of the average,. Depending on the amount of use you intend to get out of your battery (daily versus sporadically), you will want to compare amp hours for different c ratings. If you need more than 5 amps per hour you should consider having two or even more batteries.
