100 Amp Fuller Leisure Battery

Taking old electric vehicle batteries and using them to store solar energy

Here is an interesting way to use a product that is no longer of serviceable use in the product that it was designed for then recycled to do another job The question is will it work?

Part of my work at County Battery Services Ltd is to look at new and innovative products that the Company can bring to Market some time ago we launched the Powerbank a device that captures the solar energy from photovoltaic cells and stores it to be used when the sun goes down.

Old batteries and solar I think this all sound a great idea, but in reality is it feasible? If the battery has come from a crashed damaged car that is an insurance total loss then I could see it working, but the suggestion is that you take a battery that is no longer of use in a car and expect it to perform in a solar application.

I am aware that studies are being carried out no one talks about the battery life after is has left the car, It would need to be reconditioned in some way or the correct voltage could not be maintained. When ever we have swapped cells in fork truck batteries the others soon start to fail not long after and they are of low voltage with typically no more than 24 cells

The battery could be dismantled and any faulty cells could be replaced but that is a time consuming and dangerous job (400V DC). As there are lots of cells in one of these packs It would be easy to miss some, or have others fail within days of the others being replaced. It is possibly cheaper to buy a new battery and definitely more reliable.

The quest to find a cheap way to store energy I think must carry on maybe a water tower and an Archimedes Screw would be better?
