Frequently Asked by Distributors:
Does the XBATR620SL fit the Shark IONFlex IF200/IF250 and Rocket Pet Pro?
Yes, the XBATR620SL is a direct replacement for the Shark cordless vacuum battery. It is compatible with the IONFlex IF200/IF250 and Rocket Pet Pro. It is available in 2.0Ah and 2.5Ah. It has an OEM-matched latch and contacts.
What is the MOQ for the XBATR620SL replacement battery?
The standard MOQ is 100 units for the XBATR620SL. You can get paid samples of 1–10 units to make sure they fit and to validate the BMS-handshake before placing an 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 has model-specific firmware, so it charges and reports correctly on the real Shark charger. The state-of-charge, authentication, and safety lockouts work like the OEM Shark IONFlex & Rocket Pet Pro pack. It is checked and approved for 100% of the units at the end of the production line.
How do I replace the battery in my Shark IONFlex & Rocket Pet Pro?
Replacing the Shark IONFlex & Rocket Pet Pro battery is easy. First, power off the vacuum. Next, release the battery latch or clip. Then, remove the old pack. Finally, fit the XBATR620SL until it seats. You don’t need any tools or modifications. It charges on your 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 the runtime of the original pack. How long it actually lasts depends on the power mode and the accessory. The cells are matched and aged so that the pack will have the same capacity for its full cycle life.
Why is my Shark battery not charging or not holding charge — does a replacement fix it?
If your battery pack won’t hold a charge or charge properly, it’s likely that the batteries are nearing the end of their lifespan or the battery management system (BMS) has malfunctioned. The XBATR620SL has new Grade-A cells and a new BMS. This solves the “not charging” and “not holding charge” problems caused by a worn-out original pack.
Are these genuine Shark batteries or replacements?
The XBATR620SL is a high-quality aftermarket replacement — it is not an OEM Shark-branded pack. It is built with high-quality cells, a custom battery management system, and is designed to fit specific models. It has been tested against an original Shark IONFlex & Rocket Pet Pro pack on all units, and it comes with a 12-month warranty.
What cells and configuration does the XBATR620SL use?
The XBATR620SL uses high-quality 18650 cells (2500mAh each) arranged in a 6S1P configuration for a nominal 21.6V and a true rated capacity of 2.0/2.5Ah. Before assembly, cells are matched based on their capacity (±20 mAh) and internal resistance (±5 mΩ). You can specify your preferred cell brand (Samsung, LG, Panasonic, or BAK) when you place your order.
What is the warranty on the XBATR620SL?
All XBATR620SL replacement packs come with a 12-month warranty that covers manufacturing defects. Every batch of products is shipped with the following documents:
– UN38.3 test report
– IEC 62133 certificate
– MSDS
– CE Declaration of Conformity
These documents are needed to clear customs worldwide.
How is the XBATR620SL packed for shipping?
The XBATR620SL is shipped in master cartons of 30 pieces (17.35 kg gross). The battery is 168 mm long, 78 mm wide, and 51.5 mm tall. Every batch of these products has the necessary UN38.3 / IEC 62133 / CE documents.
