Is the battery also compatible if it has a different capacity?
Lithium-ion batteries have a high energy density and are among the most powerful batteries. Compared to NiMH batteries, they have a low self-discharge rate and are not subject to memory effect. They do not require regular discharging so are low-maintenance. When correctly stored, these rechargeable batteries have a long service life, are durable and have a high number of possible charging cycles. Li-ion batteries are used in various portable devices with high energy requirements e.g. smartphones, notebook computers, cameras and power tools. These batteries can also be used in radio-controlled models and telecommunication applications.

Solide, aber zu klein
Der Akku ist nach Typenschild nicht der 21,6 Volt sondern ein 22,2 Volt. Dem Motor wird das nicht schaden, aberxes ist eben nicht das "Original". Das Gehäuse wirkt richtig stabil und sauber verarbeitet. Am Dyson sitzt der Akku auch, nur eben etwas klein, sodass es nicht ganz perfekt wirkt. Man muß ihn recht fest in die Halterung drücken Die Laufzeit ist für mich eher mittelmäßig, da hatte ich mir mehr erhofft. Für den Preis ist das insgesamt okay, aber wirklich zufrieden bin ich damit nicht.
