Product Advisory: Nokia BL-5C battery

Dear Nokia Customer,

This is a product advisory for the Nokia-branded BL-5C battery manufactured by Matsushita Battery Industrial Co. Ltd. of Japan between December 2005 and November 2006. This product advisory does not apply to any other Nokia battery.

Nokia has identified that in very rare cases the affected batteries could potentially experience over heating initiated by a short circuit while charging, causing the battery to dislodge. Nokia is working closely with relevant local authorities to investigate this situation.

Nokia has several suppliers for BL-5C batteries that have collectively produced more than 300 million BL-5C batteries. This advisory applies only to the 46 million batteries manufactured by Matsushita between December 2005 and November 2006. There have been approximately 100 incidents of over heating reported globally. No serious injuries or property damage have been reported.

Consumers with a BL-5C battery subject to this advisory should note that all of the approximately 100 incidents have occurred while charging the battery. According to Nokia's knowledge this issue does not affect any other use of the mobile device. Concerned consumers may want to monitor a mobile device while charging that contains a BL-5C battery subject to this product advisory.

While the occurence in the BL-5C batteries produced by Matsushita in the time-period specified is very rare, for consumers wishing to do so, Nokia and Matsushita offer to replace for free any BL-5C battery subject to this product advisory.

The BL-5C batteries which are subject to the product advisory were used with the following Nokia models or separately as accessories:


Nokia 1100, Nokia 1100c, Nokia 1101, Nokia 1108, Nokia 1110, Nokia 1112, Nokia 1255, Nokia 1315, Nokia 1600, Nokia 2112, Nokia 2118, Nokia 2255, Nokia 2272, Nokia 2275, Nokia 2300, Nokia 2300c, Nokia 2310, Nokia 2355, Nokia 2600, Nokia 2610, Nokia 2610b, Nokia 2626, Nokia 3100, Nokia 3105, Nokia 3120, Nokia 3125, Nokia 6030, Nokia 6085, Nokia 6086, Nokia 6108, Nokia 6175i, Nokia 6178i, Nokia 6230, Nokia 6230i, Nokia 6270, Nokia 6600, Nokia 6620, Nokia 6630, Nokia 6631, Nokia 6670, Nokia 6680, Nokia 6681, Nokia 6682, Nokia 6820, Nokia 6822, Nokia 7610, Nokia N70, Nokia N71, Nokia N72, Nokia N91, Nokia E50, Nokia E60

This product advisory applies also to the following accessories:

Nokia Wireless GPS Module LD-1W, Nokia Wireless GPS Module LD-3W


“Nokia” and “BL-5C” are printed on the front of the battery. On the back of the battery, the Nokia mark appears at the top, and the battery identification number (consisting of 26 characters) is found at the bottom. If the battery identification number does not contain 26 characters, it is not subject to this product advisory.

If you are interested to know if your battery is part of this product advisory, please follow the two steps below:

1) Switch off your mobile device and check the battery model. If your battery is not a BL-5C model, you are not included in this product advisory and your product will not be replaced.

Why India Hasn’t Built Its GPT Moment (Yet)

India has the world’s third-largest startup ecosystem, a thriving developer base, and a mobile-first population larger than the US and Europe combined. Yet, no GPT-4. No DeepMind. No Amazon-style platform. Why? Innovation Isn’t Accidental—It’s Engineered The Zerodha Daily Brief recently asked why India hasn’t built a global product company like Apple. The key argument: India isn’t building for the world. It’s solving for local constraints, scale, and affordability—but global scale requires deep IP, design, and tech differentiation. It’s not just about software, it’s about systems thinking. More importantly, it answers the question: Why do countries innovate? The answer isn’t just genius or ambition—it’s incentives and ecosystems. The U.S. Defense Department, for example, accounted for nearly 70% of federal R&D funding during the Cold War. China has pumped billions into semiconductors and AI with long-term national alignment. These aren’t short-term bets—they are strategic, delibe...

From Stubborn to Smart: How I Learned to Use AI as a PM

Listen to the article in podcast format on PM-AI Diaries channel on Spotify! Ever since I published "The Death of the Stubborn PM" back in February, my inbox has been buzzing with one big question: “Okay, I get that AI is the future for product managers—but how do I actually use it?” It’s a fair ask. In that piece, I argued that PMs who resist AI are doomed to fade away, like dinosaurs refusing to evolve. As I wrote, “The stubborn PM who clings to old ways will die out, replaced by those who harness AI’s power while leaning into what makes us human.” Now, people want the playbook. So, let’s walk through it with a story—my own journey of figuring this out, backed by some sharp insights from MIT Sloan’s "When Humans and AI Work Best Together—and When Each Is Better Alone" . The Wake-Up Call Picture me a few months back: a PM buried in work, juggling a dozen tasks, and feeling like there weren’t enough hours in the day. Writing user stories, sketching ideas, track...

The Death of the Stubborn PM

Product Management is undergoing a seismic shift, much like programming did when compilers replaced assembly language or when Agile dismantled waterfall dogma. Stubborn PMs who cling to outdated rituals—like treating PRDs as sacred texts—will fade into irrelevance. The future belongs to those who embrace AI as a collaborator, not a threat.   AI Will Disrupt the Tactics, Not the Thinking   Historically, tools abstracted manual work: compilers automated code translation, A/B testing replaced gut-driven debates. Similarly, AI will automate tactical PM tasks—data aggregation, routine prioritization, even drafting specs. But this is liberating, not limiting.   The stubborn PM obsesses over *how* to write a PRD; the adaptive PM focuses on *why* a product should exist. AI can’t replicate judgment calls that demand intuition: interpreting unmet customer needs, balancing ethics with growth, or navigating ambiguity when data is sparse. As AI handles execution, the PM...
