In the "video" battery size D. After the recover I used also for 3 batteries: one lemon NOT squeese (pulp) for to have sort of support and membrane. More clearly: I've changed that black-powder-paste, with lemon-pulp (one piece) and lemon-juice (for complet fill the whole volume). Short : a method of how "dead-batterys" can be "repaired" to regain some life.
SOON MORE !!!
