Heavy-duty cells built for work.
We strip out the retail markup to deliver drop-tested, high-capacity replacement batteries with the exact runtime and thermal safety active tradespeople demand.
We exist to break the expensive OEM monopoly on replacement power tool cells.
No cheap plastic casings. No inflated retail markups. Just drop-tested, grade-A lithium-ion packs engineered to keep your crew on schedule.
Inside our grade-A cells.
We source only premium high-drain cells with advanced thermal management. Here is how we match OEM runtime under heavy load.
Thermal Protection
Advanced thermal management and copper heat sinks prevent overheating during continuous, high-load drilling on active jobsites.
High-Drain Power
Grade-A high-drain cells sustain maximum voltage under heavy load, preventing sudden stalls while cutting through dense materials.
