How to Spot Fake Batteries and Avoid Device Damage
Despite better awareness and smarter devices, counterfeit primary batteries are still everywhere in India from street kiosks to online sellers with flashy discounts. These fakes often look just like the real thing but:
- Die in hours
- Leak and damage devices
- Cause inaccurate readings in medical tools
- Offer zero safety or warranty
And because button and coin cells are small and cheap-looking, it’s easy to fall into the “they’re all the same” trap until your ₹5000 watch stops or your thermometer gives false readings.
1. Batteries That Are Commonly Faked in India
| Battery Type | Risk Level | Common Devices Used In |
|---|---|---|
| Silver Oxide (SR series) | High | Watches, glucometers, thermometers |
| Lithium Coin (CR2032, CR1632) | High | Remotes, key fobs, Bluetooth devices |
| AA/AAA Alkaline | Moderate | Toys, torches, wireless keyboards |
| CR123A, CR2 | Moderate-High | Flashlights, DSLR accessories, security sensors |
Most fakes come unbranded, loosely packaged, or suspiciously cheap but not always easy to identify without knowing what to check.
2. How to Spot a Fake Battery in India
Suspicious or Generic Packaging
- Misspelled brand names (e.g., “Energizar” instead of “Energizer”)
- No expiry date, or one printed in faded ink
- Vague terms like “Super Cell” or “Swiss Technology” with no actual brand
- Loose coin cells sold in plastic pouches or without factory seal
Unrealistically Low Prices
- CR2032s that normally cost ₹80-₹120 sold for ₹20 in bulk
- AA/AAA “alkaline” packs for ₹10 that last less than a day
- “Combo packs” of assorted cells with unknown source
Light Weight or Flimsy Feel
- Fakes are often underweight because they skimp on materials
- May rattle slightly or feel less dense than a branded cell
Poor Performance or Strange Behavior
- Battery dies within 24-48 hours
- Watch time resets or slows unexpectedly
- Glucometer gives fluctuating readings
- Device overheats, refuses to turn on, or drains battery quickly
- Leakage or corrosion within days of use
3. Where Fake Batteries Are Often Found in India
- Small watch repair stalls
- Recharge shops and local electronics counters
- Online sellers on lesser-known platforms
- Discount electronics outlets and bulk combo deals
4. How to Avoid Fake Batteries
Buy From Trusted Sellers
- Online: Amazon (sold by brand), Flipkart Assured, Tata 1mg
- Offline: Reputable watch stores, electronics chains, medical stores
Stick to Trusted Brands
- Silver Oxide: Maxell, Sony, Renata, Energizer, Panasonic, Varta
- Lithium Coin: Duracell, Energizer, Panasonic
- Alkaline AA/AAA: Duracell, Eveready, GP
Check for These Before Buying
- Proper expiry date
- Consistent font, spelling, and packaging quality
- Matching battery code (SR626SW ≠ AG4 ≠ CR1025)
Be Wary of Generic Alternatives
- “AG series” batteries often sold as cheaper replacements for SR (silver oxide) but don’t perform the same
- “CR” lithium coins sold loosely may be repackaged or expired
5. What Happens If You Use a Fake Battery
- Device Damage: Leaks can destroy contacts or logic boards
- Inaccuracy: Faulty output affects glucometers, thermometers, remotes
- Shortened Battery Life: Replacing every 1-2 days instead of 6-12 months
- Safety Risk: In rare cases, fake lithium cells can overheat or explode
Especially in watches, hearing aids, or medical devices a fake cell can cost more than just a few rupees. It can damage your device, safety, and trust.
6. Don’t Let a ₹30 Cell Destroy Your ₹5000 Watch
With so many button and coin cells flooding the Indian market, it’s easy to get tricked. But now you know what to look for.
If you’re buying a CR2032, SR920SW, or even AA battery:
- Check the brand
- Inspect the pack
- Match the code
- Don’t go for the cheapest one without a source
