Ich habe kürzlich bei Ebay ein Motorola Koffergerät 56B1A mit original-Batterien erstanden. Die Reparatur war relativ einfach, die Batterien waren natürlich mausetot. So versuchte ich in die original-Hüllen neue Batterien einzubauen, was wider Erwarten relativ einfach gelang. Für die Heizbatterie verwendete ich 4 Li-Ion Zellen, 65mm Zylinder aus defektem Laptop-Akku. Voll geladen hat die Zelle 3,7 V, zwei in Serie ergibt also 7,4 Volt, was genau passt. Für die stabförmige Anodenbatterie schaltete ich 10 handelsübliche 9V-Blocks, ergab die erforderlichen 90V.
