I have a project that I use a 12 volt 7Amp battery (lead acid battery) a RC hobby battery.
I bought a 12VDC 15A on/off remote relay kit to turn on and off two car sirens when I push the remote button.
The unit is placed outside, I use the remote to turn on and off the sirens (from inside the house). maybe 3 seconds at a time.
I have only used the remote around 10 times within a month to turn on and off the sirens before the battery went dead (about 3.6 volts when checked)
My question is : I would have thought the battery would have lasted much longer, is the 12V remote draining the battery even when not pushing the button? or is this just the way it is when batteries are placed outside and not used enough?
Thanks for reading, hope you can help on what I am doing wrong!
