sign off on our solar power system. I didn't know I needed to have a separate

Hour means how much current a battery will discharge over a period of one hour.
Higher numbers here reflect a long battery runtime and or higher storage
capacity . Higher MAH ratings do not necessarily reflect on speed but more on
runtime. For example a 2000 mAh pack will sustain a 2000 milli amp (2 amp) draw
for one hour before dropping to a voltage level that is considered
Devices designed to use "9V" batteries are generally
designed to work properly over the operating voltage range of a "9V" battery,
