Amp hour draw question for LED setups Answered
Hi, I have an led setup that is drawing .39A @12v.
I am running it with a 4.5ah alarm panel battery.
My questions are:
Is there a way to calculate the how long this set up will run knowing that leds stop working when the power dips under a certain amount?
I have been running this set up for about 4 hours at a time, about once a week without issues for several years. I always top off the battery at a 2amp setting on the charger. It always takes less than an hour to top off after 4 hours of use. This is probably good for the battery cause it shows that it isn't being drawn down much during it's 4 hours of use. I then put it on a float charger for storage till the following week. Could this be run on a smaller battery without affecting the battery life? I would like to run the smallest and lightest set up possible while maintaining the health of the sealed battery that probably doesn't like heavy recharge cycles. What is the smallest I should go while keeping the battery healthy? Thanks for the info.
