Frequently Asked by Distributors

Does the XBATR620SL fit the Shark IONFlex IF200/IF250 and Rocket Pet Pro?
Yes. The XBATR620SL is a direct Shark cordless vacuum battery replacement for the IONFlex IF200 / IF250 and Rocket Pet Pro, available in 2.0Ah and 2.5Ah, with OEM-matched latch and contacts.
What is the MOQ for the XBATR620SL replacement battery?
Standard MOQ is 100 units for the XBATR620SL. Paid samples of 1–10 units are available for fit and BMS-handshake validation before a production order. Private-label or custom-spec runs start at 500 units.
Is the XBATR620SL drop-in compatible with the original Shark charger or dock?
Yes. The XBATR620SL BMS is flashed with model-specific firmware so it charges and reports correctly on the genuine Shark charger — state-of-charge, authentication, and safety lockouts behave like the OEM Shark IONFlex & Rocket Pet Pro pack. Validated on 100% of units at end-of-line.
How do I replace the battery in my Shark IONFlex & Rocket Pet Pro?
Replacing the Shark IONFlex & Rocket Pet Pro battery is straightforward: power off the vacuum, release the battery latch or clip, remove the old pack, and fit the XBATR620SL until it seats. No tools or modification needed — it charges on your genuine Shark charger or dock.
How long does the XBATR620SL battery last per charge?
The XBATR620SL delivers a true 2.0/2.5Ah at 21.6V, matching or exceeding original-pack runtime. Actual runtime depends on power mode and accessory. Cells are matched and aged so the pack holds capacity over its full cycle life.
Why is my Shark battery not charging or not holding charge — does a replacement fix it?
A pack that won't hold charge or won't charge usually means end-of-life cells or a failed BMS. A new XBATR620SL with fresh Grade-A cells and a fresh BMS resolves 'not charging' and 'not holding charge' faults caused by a worn-out original pack.
Are these genuine Shark batteries or replacements?
The XBATR620SL is a high-quality aftermarket replacement — not an OEM Shark-branded pack. It is built with Grade-A tier-1 cells, a model-specific BMS, and OEM-matched fit, validated against an original Shark IONFlex & Rocket Pet Pro pack on 100% of units, and backed by a 12-month warranty.
What cells and configuration does the XBATR620SL use?
The XBATR620SL uses Grade-A 18650 cells (2500mAh each) in a 6S1P configuration for a nominal 21.6V and a true rated capacity of 2.0/2.5Ah. Cells are matched by capacity (±20 mAh) and internal resistance (±5 mΩ) before assembly. Preferred cell brand (Samsung / LG / Panasonic / BAK) can be specified at order.
What is the warranty on the XBATR620SL?
All XBATR620SL replacement packs carry a 12-month warranty against manufacturing defects. Every batch ships with UN38.3 test report, IEC 62133 certificate, MSDS and CE Declaration of Conformity for smooth customs clearance worldwide.
How is the XBATR620SL packed for shipping?
The XBATR620SL ships 30 pcs per master carton (17.35 kg gross). Battery dimensions 168 × 78 × 51.5 mm. Every batch ships with full UN38.3 / IEC 62133 / CE documentation.
