If I wanted to make a homemade gel-cell or or AGM battery, what materials would I need?
I am thinking of building a homemade UPS (two actually) for use in my home. We have very bad power spikes and drops, and I have gone through 5 power strips in 4 months. My first thought was simply an off the shelf inverter and some lead acid (gel or AGM) batteries... but then I thought, why not go all out and make it all homemade? I know I can make an inverter myself, but have never attempted to cobble together a battery of any sort (unless you go back a couple decades and count the potato battery).
I'm planning on making the UPS my first instructable, and would love to include (or have a second instructable on) the homemade battery as well. I'd want something that is deep cycle and which can support 1kw of continuous load pretty much 24/7 (assuming it is on the mains being recharged constantly).
