Portable Li-ion Cells and Batteries Testing Services

Portable Li-ion Cells and Batteries Testing at Matrix Test Labs

Lithium-ion cells inside the phone in your pocket, the watch on your wrist and the laptop on your desk must each individually clear IEC 62133-2 / IS 16046 (Part 2) before sale. As an NABL accredited testing laboratory recognised by BIS and TEC, Matrix Test Labs delivers portable li-ion cells and batteries testing that is accepted by Indian regulators, OEMs and international buyers alike. Our laboratory in Delhi combines calibrated infrastructure with engineers who live and breathe these standards every day.

Whether you are an established brand putting a new generation of portable sealed lithium-ion cells and battery packs on the market, an importer chasing BIS compliance, or an R&D team validating a fresh design, our test reports give you the confidence to launch — and the documentation to defend that launch in front of any regulator or auditor.

Standards we test portable sealed lithium-ion cells and battery packs to

• IS 16046 (Part 2) — Safety of sealed portable lithium systems
• IEC 62133-2 — Lithium portable cell safety
• IS 16893 (Part 2) — Safety of lithium battery systems
• UN 38.3 — Transport safety

Our scope of NABL accreditation is reviewed every cycle to keep pace with revisions in IS, IEC, AIS and TEC specifications, so the test report we hand you today is the one your homologation committee will accept tomorrow.

What we test on portable sealed lithium-ion cells and battery packs

• External short — short circuit < 100 mΩ
• Continuous low-rate charge — 28 days at 0.05 C
• Forced discharge — 1 C reverse for component cells
• Free fall — drop from 1 m, three orientations
• Crush — 13 kN until 10 % deformation

Each parameter is executed under controlled environmental conditions on calibrated equipment with full traceability to national reference standards. Test data is captured digitally, reviewed by a qualified test engineer and signed off by an authorised signatory before the report leaves the laboratory.

Industries we serve

• smartphone and tablet brands
• power bank importers
• wearable device makers
• cordless tool OEMs
• portable medical devices

Why leading brands choose Matrix Test Labs

Matrix Test Labs is one of the few independent third-party laboratories in Delhi that combines NABL accreditation, BIS recognition and TEC empanelment under a single roof. That means a portable sealed lithium-ion cells and battery packs test request submitted at our gate can move through electrical safety, mechanical safety, environmental qualification and, where applicable, performance benchmarking without ever leaving the campus — cutting weeks from your typical product release timeline.

Our engineering team is fluent in IS, IEC, AIS, TEC and EN standards, and we offer pre-compliance support so that the first formal test sequence is also the last one you have to pay for. From a single component verification to a complete certification dossier, every engagement begins with a free scoping call to map your specific portable sealed lithium-ion cells and battery packs against the applicable standards.

Turnaround time and reporting

Typical turnaround for a complete portable li-ion cells and batteries testing sequence is 3 to 6 weeks, depending on sample availability and the depth of the test plan. Express slots are available for urgent homologation deadlines. Final reports are delivered as digital, signed PDFs along with a hard copy and supporting raw data on request. Every test report carries the NABL emblem along with our laboratory accreditation number, making it readily acceptable to BIS certification bodies, TEC, ARAI, ICAT, regulatory authorities and overseas buyers.

Sample submission and what to expect

To begin portable li-ion cells and batteries testing, you will typically need to submit between 3 and 8 representative samples of the portable sealed lithium-ion cells and battery packs along with their technical datasheet, declared ratings, circuit diagrams and a copy of the user manual. Our laboratory coordinator will confirm the exact sample quantity once the scope is finalised. Samples can be hand-delivered to our Delhi facility, sent by courier with our consignment note, or collected on request within Delhi-NCR. Each sample is uniquely barcoded on arrival and tracked through the testing pipeline, giving you full visibility on progress at every stage.

Frequently asked questions

Will the test report be accepted by BIS / TEC / ARAI? Yes — because our laboratory is NABL accredited and recognised under the relevant Indian schemes, reports from Matrix Test Labs are accepted by all major Indian certification bodies and regulatory authorities for portable sealed lithium-ion cells and battery packs.

Do you offer pre-compliance testing? Absolutely. We routinely run a pre-compliance sweep on prototype units so design teams can correct issues before the formal portable li-ion cells and batteries testing sequence begins, eliminating expensive re-test cycles.

Can you help with retest after a design change? Yes — partial retests against affected clauses are scoped on a case-by-case basis and usually cost a fraction of a full sequence.
