Due to breaking my leg and not being insured when I did so ... as well as at the same time my 3 month old 20a 36v BMA supplied battery developing problems I have been forced to look for options to power my bike, which has been the only way I can get around, the bike has been able to get me around on power only as I cannot peddle until the screws in my ankle are removed, the fact that my battery has been problematic has motivated me to look hard for a solution that I can afford ... I have a trailer which I can attach to one of my my bikes ... so the weighty Led Acid Batteries became an option, new prices of Led Acid batteries make cheap LIFPO4 batteries look like a better option as the prices were comparable amp hour wise, something I was not keen on as they are reported to be short lived ... in the past my experience with Led Acid has been bad, make one mistake and they are stuffed!! and it's time to buy more ... had one set last 2 weeks and all I was asking of them was 11 kilometres (about 7.5 miles) before charging and I peddled all the way as it has been about getting to and from work fast as possible and not so much about making the run easier ... these were six 7amp hour 12 volt golf cart batteries wired to give 36 volts, they were heavy enough to cause the rear wheel to buckle under braking ...
So here's the thing-
Found a video on Ebay where this Canadian guy took a sad Old Led Acid battery and converted it to a "Led Alkaline Battery", not only did it go from a very sad state but it started his truck

Please, anyone doing this, please wear eye protection, cloths that will protect you and have a hose or shower close by in case of accident, as well as please dispose of the acid and anything that may be environmentally damaging, toxic to humans or any life form etc properly.
Upon further research I found that there is a slowly growing realisation that this not only works, makes led based flooded batteries rejuvenate, but may be technology that may replace Acid based cells.
Further sites I found.

Of course weight is still a problem, in my case I'm going to use my bike trailer to cart 3 batteries to power my 36v 800 watt bike, these batteries I will fix using this method to get me around until I have a decent income again and can replace my LIFPO4, it seems the claims are old batteries not only revive, but have a deeper cycle and faster recharge time.
