India doesn't regulate battery safety under one single rulebook. Depending on what you manufacture, assemble, or sell — solar batteries, vehicle batteries, lithium-ion cells, or EV traction packs — a different combination of standards applies, enforced by different bodies. Get the wrong one (or miss one entirely), and you can't legally register your product, let alone sell it through retail or B2B channels.
This guide breaks down the four standards that actually govern battery safety in India today, who enforces each one, and what entrepreneurs entering battery manufacturing or assembly need to budget for in time and cost.
Battery safety regulation in India has tightened sharply in recent years — driven largely by a string of EV fire incidents that exposed gaps in traction battery pack design and testing. The government's response came in two parallel tracks: the Bureau of Indian Standards (BIS) strengthened certification requirements for battery cells sold across solar, consumer, and industrial applications, while the Ministry of Road Transport and Highways (MoRTH), through the Automotive Research Association of India (ARAI), introduced and then amended a dedicated safety standard for EV battery packs.
For anyone manufacturing, assembling, or importing batteries in India — whether for a solar off-grid system, an electric two-wheeler, or a stationary energy storage unit — this means compliance isn't optional, and it isn't a single checkbox. Selling a non-compliant product can mean denied market access, retailer and distributor rejection, and in serious cases, legal liability if a safety failure occurs in the field.
| Standard | Governing Body | Applies To | Key Tests | Mandatory Since |
|---|---|---|---|---|
| IS 16270:2023 | BIS / MNRE | Solar PV batteries, all chemistries | Capacity, cyclic endurance, charge retention | 2025 (Solar Goods Order) |
| IS 7372:1995 | BIS | Lead-acid starting batteries, ICE vehicles | Capacity, dimensions, durability | 1995 |
| IS 16046 (Parts 1&2) | BIS | Portable rechargeable lithium-ion & nickel-system cells | Short-circuit, overcharge, crush, thermal abuse | 2018 |
| AIS 156 | MoRTH / ARAI | EV traction battery packs (REESS) | Thermal propagation, vibration, crash, IP rating | 2022 (Phase 1), 2023 (Phase 2) |

IS 16270:2023 replaced the earlier IS 16270:2014 and now sits at the centre of India's solar battery compliance landscape. It covers secondary (rechargeable) cells and batteries used in solar PV applications — including lead-acid, VRLA, and lithium chemistries used in off-grid and hybrid solar systems. Since 2025, registration under this standard has been made mandatory by MNRE's Solar Goods (Requirement for Compulsory Registration) Order, meaning solar battery manufacturers and importers must register their products before they can be legally sold in the Indian market.
Testing under IS 16270 evaluates rated capacity, charge retention, and cyclic endurance under solar-specific charge/discharge patterns — different from how a battery would be tested for, say, automotive starting duty.
If you're building a career or business in solar manufacturing, installation, or system design — where battery selection and compliance directly affect project viability — our Solar Energy learning hub and Solar Engineer Certificate Course both cover this in practical depth.
IS 7372:1995 is India's longest-standing battery standard still in active use, governing lead-acid starting, lighting, and ignition (SLI) batteries for conventional internal-combustion-engine vehicles. It specifies dimensional standards (so batteries fit standard vehicle bays), terminal layout, and minimum performance requirements like cold-cranking capacity and durability.
This standard is the least relevant of the four for solar, EV, or battery-storage entrepreneurs specifically — it governs conventional vehicle batteries, not EV traction packs or stationary storage. It's included here because manufacturers occasionally produce across both automotive and EV/solar product lines, and conflating IS 7372 with AIS 156 (a common mistake) can lead to testing the wrong product against the wrong standard entirely.
IS 16046 is the Indian equivalent of the international IEC 62133 standard and forms the basis of BIS's Compulsory Registration Scheme (CRS) for portable lithium-ion and nickel-system rechargeable cells and batteries. It's the standard most consumer electronics, power banks, e-cycle batteries, and small lithium-ion packs are tested against.
Testing covers short-circuit response, overcharge and over-discharge protection, crush and impact resistance, and thermal abuse — the core failure modes responsible for most lithium-ion safety incidents. BIS-CRS registration under IS 16046 is a prerequisite for legally selling most lithium-ion battery products in India.
Our Mobility Li-ion Battery Training course walks through these exact test protocols hands-on, alongside the related Li-ion vs LiFePO4 vs Lead-Acid comparison guide for choosing the right chemistry before you even get to compliance testing.
AIS 156 stands apart from the three BIS standards above — it's an Automotive Industry Standard administered by the Ministry of Road Transport and Highways (MoRTH) through ARAI, not BIS. It governs the safety of the complete EV traction battery pack (technically, the "Rechargeable Energy Storage System" or REESS) — not just the individual cells inside it.
AIS 156 was introduced in phases. Phase 1 came into effect in December 2022, with a stricter Phase 2 amendment following in March 2023 — both rolled out in direct response to a wave of EV fire incidents that exposed gaps in pack-level thermal and mechanical safety. Testing covers thermal propagation (how a single cell failure is contained from spreading), vibration and mechanical shock resistance, crash safety, and ingress protection (IP) ratings.
Because AIS 156 tests the assembled pack — BMS, enclosure, and cells together — it's typically the standard that requires the most specialised testing infrastructure, and the one most EV battery assemblers underestimate the cost and timeline for. Our Mobility Li-ion Battery Training course includes hands-on AIS-156 compliance training, alongside our related deep-dive on the Battery Management System (BMS) — the component most directly tied to AIS 156's thermal safety requirements.

Budgeting for certification is one of the most under-planned parts of launching a battery manufacturing or assembly business in India. Costs and timelines vary significantly by standard, product complexity, and whether retesting is needed after an initial failure — so treat the figures below as planning ranges, not fixed quotes.
The real cost of skipping certification isn't the certification fee you avoided — it's the market access you lose. Retailers, distributors, and B2B buyers increasingly ask for BIS/AIS documentation before they'll stock or integrate a product, and non-compliant batteries face legal exposure if a safety incident occurs in the field, regardless of intent.
What separates battery assemblers who scale from those who get shut down isn't paperwork knowledge — it's hands-on familiarity with the actual test protocols, so testing failures get caught and fixed in-house before they reach a lab and cost you a retest cycle. That's the gap our Mobility Li-ion Battery Training course is built to close.
Compliance also opens a parallel career path worth knowing about: QA/Compliance Engineer roles are in growing demand at battery manufacturers, EV OEMs, and testing labs across India — for entrepreneurs scaling past their first production run, this is often the first specialised hire worth making.
