Super Stars Cordless Flaring Tool Battery 11.1V 2200mAh (ST-E800 / ST-E900 / ST-E300A)

Super Stars 11.1 V / 2200 mAh Li-ion battery is, for Super Stars cordless flaring and tube expanding tools, the original spare battery. Compatibility list stated by the manufacturer on the box label: ST-E800, ST-E900 and ST-E300A series. With its slide-in design and side locking latch, it attaches to the tool in one motion; the contact surfaces (+/−) are marked on the body.

Which Tools It Fits and What It Does

• ST-E800 series — cordless flaring tools (including ST-E800A)
• ST-E900 series — cordless automatic flaring tools (including ST-E900A)
• ST-E300A series — cordless tube expanding (swaging) tools (ST-E300A / ST-E300AL)
• Second battery = uninterrupted work: For installers working at pace in the field, rotating one battery in the tool and one on the charger is far more efficient than trying to get through the day on a single battery.
• The right time for a spare: Li-ion batteries are consumables; replacing a battery whose capacity has dropped (noticeably fewer flares per charge) without waiting restores the tool's performance.

Technical Specifications and Lithium Battery Usage Rules

• Product Code: 47.01.38

• 🔧 Charge only with the tool's own charger. This is the first warning on the manufacturer's label; chargers with a different voltage/current upset the cell balance and cause the battery to swell.
• Do not short-circuit the terminals or open the battery. Carry it in a compartment of the tool bag where the contacts cannot touch metal tools (wrenches, pliers).
• Keep away from heat and fire. In summer, do not leave it inside a closed vehicle, behind a sunny window or near a heat source.
• Store half-charged if not used for a long time. A Li-ion cell left completely empty falls into deep discharge and may no longer accept a charge; do a check charge every few months.
• Verify compatibility from the tool model. If the model name on your tool's label starts with ST-E800, ST-E900 or ST-E300A, this battery fits; if it is a different series, ask us before ordering.
