Description
xCell Lab 10440 Cylindrical Battery Cases – 100 pcs with Anti-Explosive Cap and Insulating O-Ring [AAA-Size | Nickel-Plated Steel]
Durable and safe casing solution for laboratory battery prototyping
The Cell Lab™ 10440 Cylindrical Battery Case Set provides a professional, safety-enhanced enclosure for AAA-size (10440 format) lithium-ion cell assembly. Each case features an integrated anti-explosive cap, PTC thermistor, and nylon insulating O-ring, offering multi-layer protection during fabrication, testing, and operation. Designed for small-scale R&D, pilot production, and laboratory cell assembly, these cases ensure both mechanical reliability and electrical safety in every experiment.
Key Features
• Explosion-Resistant Design
Built-in safety vent releases internal gas pressure automatically when it exceeds 2.5 MPa, preventing cell rupture and ensuring safe operation under abnormal conditions.
• Integrated PTC Thermistor
Incorporates a PTC over-current protection element that interrupts the circuit at approximately 120 °C, offering superior protection against short circuits and overheating.
• Insulated Assembly
Top and bottom insulation components—including a nylon O-ring and insulating washer—prevent short-circuiting during electrode stacking and welding.
• Durable Nickel-Plated Steel Housing
The A3-grade nickel-plated steel case ensures strong mechanical integrity, excellent corrosion resistance, and stable conductivity for both prototype and pre-production testing.
• Ready for Immediate Lab Use
Each unit is preassembled with its protective components (cap + O-ring), streamlining workflow for researchers engaged in custom cell design, balancing, or layer stacking experiments.

FAQ
Q1: Are these cases reusable?
A1: While designed for laboratory use, reusing is not recommended after welding or heat exposure, as structural and sealing performance may degrade.
Q2: Are they compatible with commercial 10440 cell holders?
A2: Yes, dimensions conform to standard 10440 (AAA) form factors used in laboratory battery modules and test fixtures.
Q3: What welding method is recommended?
A3: Spot welding or ultrasonic welding is preferred; avoid excessive heat to protect the internal insulation components.
Q4: Is the PTC thermistor user-replaceable?
A4: No, the PTC device is integrated within the cap for safety and should not be disassembled.
