I have only done a small bit of research in regards to home made DIY batteries. The 2 major types are Lead Acid and Nickle Iron. Lead is easy enough to melt and it sticks to anything solder would stick to. I think making plates would be easy enough to do. Nickle Iron could be made using welding rods of Nickle and Iron. Sulfuric Acid seems to be something that might be hard to come by in amounts larger than 1 liter at a time. I think getting this from used batteries might be the best option. Potasium Hydroxide for ni fe batteries might be easy to make because its the same thing that makes home made lye soap. Pot ash. For battery cases, I think cermaics would be a good way to go. Anyone else have any ideas?June 25, 2011 at 12:00 am #65241chowanParticipant
any battery store could sell you gallons of sulfuric acid making it is
tricky and not worth the hassel when it is so cheap.
lead is easy to work with and i think you need pure lead not lead alloys like in wheel weights and solder.
i saw a youtube vid of a guy who made his own led cell and if i remember right
the trick was slow repeated charges to build up the compound that is on the plates.
modern battery plates are made porous to give better cranking amps but im not sure if that improves the amp hours.from my understanding the charge on the plates is all stored in the lead compound that forms on the plates.
i have been wanting to try this myself and though about using old glass
bottles but if i ever find those old glass cases i will definitly try to rebuild them.June 25, 2011 at 12:00 am #65243June 25, 2011 at 12:00 am #65248
Hey guys sorry to disappoint you but the fabrication of real batteries is anything but simple,regardless of what the science lab experiments will lead you to think. I grew up in and spent my entire working life in the manufacturing world. Making battery plates is not a trivial activity. Contrary to descriptions these plates are not just solid metal. Home made batteries will work but do not have anywhere near the storage capacity. Energy storage at home is better done using either gaseous or liquid media such as stored methnane or biogas, water resevoirs, ethanol production or pumped storage.June 25, 2011 at 12:00 am #65261
Yes indeed DIY batteries would be heavier and larger than performance equivalent manufactured batteries. Also cost of metals might make them more expensive. I was just curious about in a pinch what one might be able to do. Or if you just wanted to make them for the heck of it.June 25, 2011 at 12:00 am #65263
In a pinch or maybe even on a regular basis I would be more inclined to rely on a genverter. It would deliver far more Wats per cubic inch of equipment storage volume.If you select one that runs on bottled gas like propane you can realistically expect a stored unit to be good for five years or more. You can’t do that with batteries. We already have the storage technology for other stuff so it will last years.
The construction spec for Canadian Ice breakers calls for it to survive two years abandonment in arctic ice and still be able to hand start the 10,000 HP diesel engines. The theory being you should be able to helicopter in a two man crew to a ship stuck in ice and be able to hand start everything using only a hand bag of tools. Don’t believe me? Think back to 1950’s era caterpillar crawlers with pony engines to start them. With you being a trucker this should be familiar territory to you. <smile> Or aint you that old?June 25, 2011 at 12:00 am #65264
Hey Caverdude can you give us more information on Carbide lamps? You mentioned having them while cave exploring. This would also be a neat idea for long term storage for emergency use. We used to carry life rings on board ships that had a carbide lamp deal that was activated as you threw the ring overboard to somebody in the water. The idea being the carbide stuff would last longer in storage than any battery would.June 25, 2011 at 12:00 am #65266
Carbide lamps can be found at caving supplies, but I’m not sure that mining suppliers or night hunting suppliers carry them anymore. Carbide of course looks like rocks, water drips into the base of the lamp and a chemical reaction causes heat and accetelene gas to form. So, a person could use the accetelene cutting torch bottle to regulate gas to his lamp in a house. This would be more ideal in a stationary lighting situation. Caving suppliers also sell tools for repair and cleaning of the lamps, replacement parts etc. Petzel is a well known brand name. Carbide can also be ordered from caving suppliers. Though being hazmat shipping may be regulated. Meaning quantities shipped at one time. Premier is one brand name for a modern carbide lamp maker.
