Quality Assurance

8-Stage Quality Testing Protocol

Every Shark replacement battery passes an 8-stage inspection and test sequence before it ships. Documented per batch, traceable per serial number.

Incoming Cell Inspection

Incoming Cell Inspection

Every 18650 / 21700 cell batch is tested for capacity, internal resistance, and voltage variance against supplier datasheet specifications before entering production. Out-of-spec lots are quarantined and reported back to the cell supplier.

Standard 100% sample audit
Cell Sorting and Matching

Cell Sorting & Matching

Cells are matched by capacity (±20 mAh) and internal resistance (±5 mΩ) before pack assembly. Tight matching ensures balanced discharge across all parallel groups and extends total pack cycle life.

Standard ±20 mAh tolerance
Spot Welding and Assembly

Spot Welding & Assembly

Automated nickel-strip spot welding with real-time current monitoring. Every weld point is pull-tested for tensile strength sampling, and nickel strip resistance is measured per pack to guarantee low-loss interconnects.

Standard 2 kgf min pull strength
BMS Programming and QC

BMS Programming & QC

BMS is flashed with model-specific firmware tuned for Shark host devices. Communication handshake is verified against OEM chargers — state-of-charge reporting, authentication signals, and safety lockouts must function identically to the genuine pack.

Standard 100% handshake pass
Capacity Verification

Capacity Verification

Side-by-side discharge test against an original Shark battery pack on identical load profiles. Our replacement must deliver equal or greater rated capacity and equal or longer real-world runtime on the host vacuum.

Standard ≥100% rated capacity
Aging Test

Aging Test

48-hour aging at controlled room temperature to stabilize cells and detect early-life failures. Voltage drift is continuously monitored — any pack with abnormal self-discharge is flagged for engineering review.

Standard 48 hr aging cycle
End-of-Line Functional Test

End-of-Line Functional Test

Final EOL station verifies overcharge / over-discharge / short-circuit protections, physical latch fit on the actual Shark host device, and visual quality. 100% of packs are tested — no statistical sampling on safety functions.

Standard 100% EOL inspection
Compliance Documentation

Compliance Documentation

UN38.3 transport test reports, IEC 62133 safety certifications, MSDS sheets, and CE Declarations of Conformity are issued per production batch and shipped together with the goods — ready for customs clearance worldwide.

Standard UN38.3 + IEC 62133 + CE

FAQ

Frequently Asked Questions

Common questions from distributors, OEM partners, and wholesale buyers sourcing Shark-compatible replacement batteries.

How do I confirm a battery is compatible with my Shark vacuum model?

The fastest method is to match the OEM battery part number printed on your original Shark battery pack (for example, XBATR620SL, XBATR640SL, XBATR725SL) directly to our catalog. Our model codes mirror the Shark factory codes for unambiguous identification.

If you don't have the original battery, you can match by vacuum series + voltage: 21.6V batteries fit IONFlex and Rocket Pet Pro lines; 25.2V batteries fit IZ Pet Pro, IX series, and WS Wandvac. Send us your vacuum model number and we'll confirm the right SKU within 24 hours.

Do you offer OEM / private label / ODM services?

Yes — all three. We support private-label printing (your logo, your colors) starting at 500 pcs MOQ, full ODM development with custom enclosure tooling at 5,000+ pcs, and retail-ready packaging design (blister, color box, hang tab).

Typical ODM timeline: 14–21 days from your sample to first-article prototype, then 30–45 days to mass production. We provide engineering support including reverse engineering, mechanical CAD, BMS firmware tuning, and certification testing.

What is the minimum order quantity (MOQ)?

Sample orders: 100 pcs per SKU. Used by distributors for retail pilot testing or QC validation. Standard catalog pricing applies; shipped within 7–10 days.

Production orders: 500 pcs per SKU, with mixed SKUs accepted to reach the MOQ. Tier pricing unlocks at 1,000 / 3,000 / 5,000 pcs per SKU. Custom OEM/ODM projects: 5,000+ pcs minimum to amortize tooling costs.

How are these batteries tested against original Shark packs?

Every SKU passes our 8-stage testing protocol: incoming cell inspection, cell matching, spot welding QC, BMS programming and handshake validation, side-by-side capacity testing against the OEM Shark pack, 48-hour aging, end-of-line functional test, and final compliance documentation.

Replacement packs must deliver ≥100% rated capacity, pass handshake with OEM chargers, and demonstrate equal or longer runtime on the original Shark vacuum compared to the genuine battery.

What certifications do the batteries carry?

All Shark replacement batteries ship with the following certifications:

UN38.3 — Transport safety for air, sea, and ground shipping. IEC 62133 — International battery safety standard. CE — EU market conformity (Declaration of Conformity provided). MSDS — Material Safety Data Sheet for hazmat shipping. Additional certifications (UL, KC, PSE, FCC) available on request for specific market entry.

What is the production lead time?

Samples: 7–10 days from order confirmation. Catalog SKU production runs: 20–30 days after 30% deposit is received, depending on quantity and current factory loading. Custom OEM/ODM projects: 14–21 days for prototype, then 30–45 days for mass production after design freeze.

Urgent orders can sometimes be expedited — contact our sales team with your target ship date for current capacity.

How are batteries shipped internationally?

Lithium-ion batteries are classified as Class 9 dangerous goods, so all shipments use DG-compliant freight forwarders. Air freight is available for samples and small orders (5–10 days transit). Sea freight is standard for production orders (25–35 days to most destinations), more cost-effective for full-carton volumes.

We provide complete shipping documentation including UN38.3 test report, MSDS, and Dangerous Goods Declaration. EXW, FOB, CIF, and DDP terms all supported.

What is your warranty policy?

All Shark replacement batteries carry a 12-month warranty from the date of shipment against manufacturing defects, premature capacity loss, and BMS failures. Defective units are replaced 1-for-1; defect rate guaranteed below 0.5% per shipment.

For OEM/ODM partners, extended warranty terms (18 or 24 months) are available on negotiation. We provide root-cause analysis reports for any field failures.

Can you customize the cell type or capacity?

Yes. For each SKU we support multiple cell options: 18650 cells (lower cost, mature supply chain) or 21700 cells (higher energy density, longer runtime). Capacity range typically 2.0Ah to 4.0Ah depending on cell selection and pack configuration.

Custom requests like high-discharge cells for power-hungry models, low-temperature performance cells, or specific cell brands (LG, Samsung, Murata, BAK) can be quoted on a per-project basis.

What payment terms do you accept?

Standard terms: 30% T/T deposit on order confirmation, 70% balance against B/L copy before shipment. Accepted methods: T/T bank transfer (USD / EUR / RMB), L/C at sight for orders above USD 30,000, Western Union for small samples.

For repeat customers and OEM partners, open account terms (NET 30) can be negotiated after credit verification. PayPal accepted for sample orders under USD 1,000.
