Is the battery also compatible if it has a different capacity?
Yes! If the other technical specifications such as voltage and connections are correct, the battery is compatible. The capacity of a battery is measured in milliampere hours (mAh). If the replacement battery has a higher capacity than the original battery, it will give you a longer runtime. If the capacity is only slightly higher or lower than the original battery, this will not result in any significant changes to the runtime. You can use batteries with a different capacity without any problems.

High-quality Li-Ion cells for optimal device performance

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.

Regarding product safety:
This product has been manufactured in accordance with the regulations in force in the EU. It fulfils, among other things, the requirements of the Directive 2011/65/EU (RoHS) and CE marking. Production is carried out in compliance with the relevant regulations on product safety, environmental compatibility and quality assurance.
