Marien Starting Battery =/= Deep cell battery
I was given a Marine Starting battery. I keep killing it. I then learn that is because it is not a deep cell battery. At least I now know.

Some people use devices such as a killawatt or measure amp draw x hours. You can measure amp draw with some multimeters or devices like a fuse buddy. One of the first things I bought was a trimetric battery monitor. If using incandescent bulbs and much furnace you deplete a group battery pretty fast.
The main basic tool is a digital volt meter. With a group battery I see a lot of comments about staying above 12.4 volts or so. Some will run down to 12.2. The important part is to bring the charge up fully. More batteries die of under charging vs over charging
