This replacement battery is built specifically to power the Oster Volt cordless clipper and delivers consistent output for the duration of a charge cycle. Lithium-ion cells are used in place of older nickel-cadmium designs, giving groomers steady cutting power without the gradual power drop-off common to older battery chemistries. The battery is a detachable, drop-in unit that snaps into the Volt clipper handle without tools. Keeping a charged spare on hand lets a groomer swap batteries between animals or mid-session rather than pausing to recharge. It is intended for professional and at-home grooming of dogs, cats, horses, cattle, goats, and sheep. The battery should be charged fully before first use and stored in a cool, dry place when not in the clipper or charger.
