In the last image of the Bandi, the battery load is displayed (I believe). Can someone please give me more information about this type of battery, if they (or a form of them) are still available (and where!), and if a different value is permitted (for instance; the photo shows "PB-Akku PM3b / 6V, 2,5Ah". I can find a battery with 6V, 4Ah. Is that acceptable? Also, what is "Ah"?
I'm depending on the generosity of "there is no such thing as a stupid question." Still, I apologize for asking what, I'm sure, is elementary to the membership.
Ah stays for Ampere/hours and indicates the capacity of the battery or how many Amperes the battery can deliver if discharged in one hour. If the 4 Ah battery you found fits the place of the old one, you can use it.
Many thanks, Emilio
