Too bad this wasn't real, especially since at the end of the day, all these things are just using 18560 cells.

I tried to standardize on one system (Hikoki 18/36V). This was great as they use the same battery across consumer and pro products. But I moved from Japan to Europe and they are far less available, and more expensive. Now I buy Parkside stuff (Lidl brand) and they are probably a tier lower but better value and also use the same battery across consumer and pro products.

Anyway I felt lucky that I could buy both low and high(er) end cordless tools in two countries/brands and also find adapters to use both batteries in both sets of tools. Both systems don't have any sort of data handshake between tool and battery. Going forward, this will probably increasingly be the case so I would love for a standard to be enforced.
