18V Extended Runtime 5.0Ah Power Battery 4-Pack

Built for professionals who need continuous power across multiple tools.
This four-battery set delivers stable voltage output under demanding workloads, keeping equipment running at full performance during drilling, cutting, fastening, and grinding applications. Advanced internal electronics monitor temperature and load to prevent overload while extending battery lifespan.

Designed to run cooler and last longer than standard lithium packs, it helps reduce downtime and increases productivity across long workdays. The onboard charge indicator allows quick runtime checks so tasks can be planned without unexpected shutdowns.

More batteries ready at once means less waiting and more working — reliable energy for teams, workshops, and demanding jobsite rotation use.
