When will Inmetro certification for e-scooter batteries be released?

Studies are expected to be completed by December 2026. As of August 2026, there is still no mandatory certification — the market remains voluntary. However, regulation is being developed by Inmetro's Electromobility Working Group and should roll out soon.

Can I use a generic e-scooter battery?

Technically yes, but we don't recommend it. Generic batteries may not be compatible with your scooter's BMS (Battery Management System), causing malfunction or safety issues. Always choose original or certified batteries for your specific model, with invoice and warranty.

How much does it cost to charge an e-scooter at home?

A full charge costs between R$ 0.10 and R$ 0.30 (approx. USD 0.02–0.06) in Maringá, based on local electricity rates of about R$ 0.85/kWh. The cost varies depending on battery capacity (36V/10Ah to 48V/13Ah) and equipment.

Where can I replace an e-scooter battery in Maringá?

Look for a specialized workshop with its own technical service. At Patinep Store, we're pioneers in Maringá with 6+ years in the market, original parts, and technical diagnostics. Schedule your visit easily.

Will certified batteries be more expensive?

Certification tends to raise standards and standardize pricing. Generic batteries may become more expensive or disappear from the market. Original, quality batteries should remain accessible as volume increases.

Inmetro E-Scooter Battery Certification 2026: What's Changing

Introduction: A New Standard Is Coming

Inmetro (Brazil's National Institute of Metrology, Quality and Technology) has been working on new regulations for replacement batteries for e-scooters and e-bikes since March 2025. The studies are expected to be finalized by December 2026, and this change will directly impact anyone who uses or plans to buy an e-scooter in Maringá and across Brazil.

For now, there is no mandatory Inmetro certification for replacement batteries — the market remains voluntary. But understanding what's coming is crucial for making the best decision when replacing your battery and choosing where to buy. Here at Patinep Store, we already operate with this quality and safety vision in mind.

Inmetro's Working Group on Electromobility

In March 2025, Inmetro created a Working Group (WG) dedicated to electromobility, focusing on two main areas: lithium-ion replacement batteries for e-scooters and electric bikes, and charging systems for electric vehicles.

This work is listed in the 2025 Regulatory Agenda and has been maintained in the 2026 and 2027 agendas, showing that the topic is a national priority. According to Hercules Souza, Head of Inmetro's Regulatory Division and Regulatory Quality, the conclusion of these studies should come out by the end of 2026 — meaning very soon.

How the Market Looks TODAY: Still No Mandatory Certification

Let's be clear: in August 2026, there is still no mandatory Inmetro certification for e-scooter replacement batteries. The market remains voluntary, and anyone can sell a generic battery without undergoing any conformity evaluation.

Is this a problem? Not if you know where to go. In practice, when you replace your e-scooter battery at Patinep Store, we work with original or approved batteries for each model, with compatible BMS (Battery Management System), correct voltage, appropriate connectors, and factory warranty. The risk lies in buying from just anywhere without that traceability.

What Changes When Certification Launches

When — and if — Inmetro's regulation is published, the trend is that it will establish mandatory minimum requirements and testing standards for all replacement batteries sold in Brazil. This should include: actual charge capacity, durability, connector compatibility, protection against overcharge and short-circuit, and manufacturer traceability.

The good news: anyone already buying batteries from a specialized store with its own technical service — like here at Patinep — will be one step ahead. Formal stores already follow these criteria voluntarily, because they know quality is essential.

How to Choose a Replacement Battery NOW, Before Certification

While mandatory certification hasn't arrived, your protection comes down to 5 key points:

Buy original batteries — from the same manufacturer as your e-scooter (Foston, Bee Green, Panda, Goo Elétricos, or your model's brand). Avoid generic marketplace batteries without verified origin.
Demand technical compatibility — voltage (36V, 48V, etc.), amperage (Ah), connector type, and compatibility with your scooter's BMS.
Request an invoice and warranty — this ensures there's a legal responsible party if something goes wrong. Keep everything on file.
Install at a specialized shop — it's not just plugging in and riding away. You need to test the BMS, charge cycle, speedometer indicator, and lights.
Check the store's reputation — here at Patinep Store we're pioneers in Maringá with 6+ years in the market, 4.9 rating on Google, and our own technical service. This trust comes from doing things right from the start.

Context: The Electric Micro-Mobility Market Is Booming

Demand for e-scooters and e-bikes in Brazil has grown 40% year-over-year. This growth brings more brands, more parts, and unfortunately, more low-quality products flooding marketplace platforms. Inmetro's new regulations aim to bring safety and standardization to this fast-growing segment. For consumers in Maringá, this is good news — it means clearer rules and safer products ahead.
