If you draw 280mA continuously, the battery will last 1 hour. 140mA continuous use will last 2 hours and so on.
Its battery life is 3 to 4 hours.
48 hours
for a full battery 8-10 hours.
To answer this question the amp/hours of the battery must be stated.
Depends on the battery you buy. They come in different CCA.
It depends on how much drain is placed on the battery !
A deep cycle battery typically has a capacity of around 100 to 200 ampere-hours (Ah).
The average Canon camera battery lasts for about 2 to 4 hours, depending on the model and usage.
Up to 2 or 3 hours
That battery model will give about 1.5 hours of battery life before needing to be recharged.
A typical deep cycle battery usually has amp-hour ratings ranging from 50 to 200 amp-hours.
depends on how run down it is
