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.

Endlich wieder vernünftige Laufzeit
Der Akku passt bei meinem Dyson sauber und bringt spürbar viel Laufzeit mit. Die Verarbeitung wirkt ordentlich, nichts fühlt sich billig an, und insgesamt macht er einfach genau das, was er soll.
