Anyone know if this is recoverable or is it a visit to the scrap metal buyer
Thanks

Try connecting it up to a small 12 volt trickle charger, One without the brain that tells itself the battery is fucked. After a day or two it may take just enough charge to then be recognised by the smart charger. Even try connecting it to a medium sized solar panel (50-100 watts).

I have several car batteries that were classified as fucked, that I have running energisers around the farm. Connected up to a 120 watt panel with charge controller, they have worked fine for another 6 years. Still working today.
