If the other technical specifications, such as voltage and connectors, are compatible, the battery is suitable. A battery's capacity is measured in milliampere-hours (mAh). If the replacement battery has a higher capacity than the original, it will provide a longer runtime. If the capacity is only slightly higher or lower than the original battery, there will be no significant change in runtime. You can use batteries with different capacities without any problems.
State-of-the-art lithium-ion cells for optimal device performance

Lithium-ion batteries are among the most powerful batteries available. Compared to NiMH batteries, for example, they are characterized by low self-discharge and higher energy density. They are not subject to the memory effect and require little maintenance, as they do not need to be regularly discharged. With proper storage, Li-ion batteries have a long lifespan due to their durability and high number of possible charge cycles.
Lithium-ion batteries are used in mobile devices with high energy demands, such as smartphones, laptops, cameras, and power tools. They are also used in RC model making and photovoltaics.

Practical tip: If the capacity of our lithium-ion replacement battery is significantly higher than that of the original battery (1000mAh and above), the replacement battery may be heavier, deeper, and thicker than the original battery. It may therefore protrude slightly.
