BIS Certification for Batteries - the Complete Map, Every Battery Type

Ask "is BIS certification mandatory for batteries?" and you will get five confident, contradictory answers - because the honest answer is: it depends entirely on the battery. Indian law splits batteries across two BIS routes, one automotive regime and a voluntary layer, run by three different arms of government. Here is the entire map in one table - each row links to its dedicated deep-dive guide:

The biggest slice of the battery market - every rechargeable lithium and nickel cell and battery for portable applications - sits under the Electronics and Information Technology Goods (Requirement of Compulsory Registration) Order, 2021, issued by the Ministry of Electronics and Information Technology (MeitY). Batteries are one of the oldest CRS entries, first notified on 7 November 2014, so enforcement here is mature: customs checks R-numbers, marketplaces verify them against the BIS database, and unregistered stock gets delisted and seized as routine.

The mechanics: testing at a BIS-recognised laboratory against IS 16046 (Part 1) for nickel systems or IS 16046 (Part 2) for lithium systems, an online application, and grant of a Standard Mark with a unique R-number - per manufacturer, per factory location. Foreign factories register through an Authorized Indian Representative (AIR). No factory audit in the normal course - which is why CRS runs faster (typically 4-6 weeks) than the ISI route.

Fresh and consequential: by order dated 3 February 2026, MeitY made rated capacity verification mandatory for lithium cells and batteries under IS 16046 (Part 2). The trigger was rampant mAh misdeclaration; the fix is measurement - capacity must now be tested per Clause 7.3.1 of IS 16047 (Part 3):2018 / IEC 61960-3:2017 (discharge performance at 20°C) at a BIS-recognised lab and reported in the modified Unified Test Report.

• Registrations valid up to 30 April 2027: comply by 30 April 2027.
• Registrations valid beyond that: comply by the licence validity date.
• After 30 April 2027: no registration granted without rated-capacity testing in the report.

The AA in your remote follows a different law entirely. Multipurpose dry batteries - zinc-carbon primary cells in R03/R6/R14/R20 sizes - have been under compulsory ISI certification for decades, via the Multipurpose Dry Batteries (Quality Control) Order issued in the BIS Act, 1986 era. The route is Scheme-I: factory assessment, sample testing at Indian BIS-recognised labs, and a licence with a CM/L number - the classic ISI Mark process, with the 2026 upgrade that licences now run up to 5 years.

Everything else in the battery world is - today - voluntary at BIS, with two big caveats: buyers often make it commercially mandatory, and the regulatory direction is one-way. The quick tour:

Deep dives: lead-acid batteries (including the BWMR EPR obligations) and solar, storage & EV batteries (including the AIS-156 clarity most of the market lacks).

One CRS detail that surprises people: the registration is granted per factory location, per Indian Standard, per brand/model series. A brand sourcing cells from two Chinese factories needs two registrations; a factory making both cells and packs may need the models covered appropriately. And traders or importers cannot hold the registration - it always belongs to the actual manufacturer, with the AIR carrying legal responsibility in India for foreign makers.

Documentation falls into three broad groups. Getting the format right is the single biggest cause of delay for first-time applicants, which is exactly the part we take off your plate:

• Administrative: company registration, factory licence/proof, trademark or brand proof, and - for foreign makers - the Authorized Indian Representative appointment and AIR company documents.
• Technical: product specification/datasheet, model list with series-family logic, critical component details (cells, protection circuit), and the BIS-recognised lab test report.
• Quality control: factory quality controls, test setup and marking/labelling artwork including the Standard Mark with registration number.

CRS route (lithium/nickel): samples to a BIS-recognised lab (IATA dangerous-goods handling for lithium), testing to the applicable Part of IS 16046 - now plus the IS 16047 capacity test for lithium - online application, grant of R-number. Typically 4-6 weeks.

ISI route (dry batteries; voluntary lead-acid/solar): documentation, factory assessment, sample drawal, Indian lab testing, licence with CM/L. Typically 4-6 weeks for prepared Indian files; longer via FMCS for foreign factories (roughly 6-10 weeks and beyond).

CRS registrations are typically granted for 2 years and renewed for periods up to 5 years. Scheme-I ISI licences now run up to 5 years under the BIS (Conformity Assessment) Amendment Regulations, 2026 (25 February 2026), with fees payable annually in advance alongside a production statement - miss the date and suspension provisions bite. And for lithium specifically, remember the 2026 twist: renewals now interact with the rated-capacity deadline of 30 April 2027.

CRS products carry the Standard Mark with the R-number; ISI products carry the ISI Mark with the CM/L number. They are not interchangeable, and buyers increasingly know the difference - e-commerce platforms verify R-numbers on battery listings against the BIS database, while tender scrutineers verify CM/L licences. Since the 2026 capacity mandate, lithium labels carry a further burden: the declared mAh must match the tested Unified Test Report figure.

BIS is the certifying and enforcing authority, and non-compliance is dealt with under the BIS Act, 2016:

• Seizure of stock from the factory, warehouse or marketplace - including e-commerce delistings.
• Customs detention of imported consignments without valid registration and marking.
• Fines and imprisonment - for a first offence, imprisonment up to two years or a fine of at least two lakh rupees, rising steeply for repeat offences.
• Loss of buyers - device brands, EV/electronics OEMs and institutional buyers verify the registration number before the price.

Batteries are the one product family where two different BIS routes meet - MeitY's CRS registration for lithium and nickel systems, and the classic ISI Mark for dry batteries - plus a fast-moving layer of fresh rules like the February 2026 rated-capacity mandate.
