The Mirka Intelligent Battery BPA10850 battery pack is a rechargeable lithium-ion battery made for Mirka cordless tools that need steady power and predictable runtime. This is a power tool battery pack designed for powering Mirka 10.8V cordless tools. Model Number: BPA10850. If you already run Mirka cordless equipment, this is the battery that keeps the tool working without tying you to a cord.

What matters here is the balance between runtime and recharge speed. The BPA10850 is rated at 11.1V and 5.0Ah, with 55.5Wh of stored energy and a six-cell design. In real use, that means longer stretches of work before swapping batteries, while the approximate 1.5-hour charge time helps keep your rotation moving when one pack is on the charger and the other is in the tool.

Mirka also builds more intelligence into this pack than you get with a basic replacement battery. The official product information calls out precise capacity measurement based on a coulomb counter. That matters because a battery gauge is only useful if it is accurate. Better charge tracking helps you plan the job, avoid mid-task shutdowns, and keep tabs on battery condition over time.

From a practical standpoint, this battery pack is about jobsite efficiency. It is rechargeable, compact, and purpose-built for Mirka's cordless platform rather than being a generic fitment. If you depend on cordless sanding or other Mirka cordless tool use, a dedicated spare battery pack is one of the easiest ways to avoid downtime.

This is a good fit for pros who already own compatible Mirka cordless tools and want dependable backup power, as well as serious users who would rather keep working than wait on a charger. It is especially useful for anyone running repeated cycles where runtime consistency matters more than raw peak output. The main thing to know up front is simple: this listing is for the battery pack, and the charger is not included.
