Counterfeit vape batteries pose 5 sustained dangers ranked by severity + sustained UK Trading Standards monitored authentic supply critical + sustained safety priority. Risk 1 (CRITICAL): Thermal runaway + fire: counterfeit cells often use lower-grade chemistry + unstable manufacturing + sustained increased thermal runaway probability + sustained UK fire service incident risk + sustained safety priority + UK fire services regularly attend incidents involving non-authentic batteries. Risk 2 (HIGH): Inflated CDR claims: counterfeits often print higher CDR than authentic Efest + sustained vape mod overdraw + sustained battery damage + sustained safety risk + sustained importance of using Mooch-tested CDR for genuine cells (counterfeits never Mooch-tested). Risk 3 (HIGH): Missing safety features: counterfeit cells may lack vent holes + safety insulators + proper electrolyte composition + sustained safety mechanism failures during stress + sustained increased risk vs authentic Efest IMR with proper safety features. Risk 4 (MODERATE): Reduced capacity + runtime: counterfeits often deliver below printed mAh capacity + sustained reduced runtime + sustained customer disappointment + sustained value loss vs authentic Efest UK retailer purchase. Risk 5 (MODERATE): Reduced battery life: counterfeit cells often degrade faster than authentic + sustained reduced ~300-500 cycle life + sustained reduced ~6-24 month UK retailer expected life + sustained shorter ownership value + sustained replacement cost. Authenticity verification (5 checks): 1. UK retailer purchase: established UK retailers (UK Companies House + VAT registered + UK Trading Standards monitored) supply authentic Efest + sustained UK consumer protection. 2. Holographic authentication label: genuine Efest batteries feature holographic security label on packaging + sustained brand authenticity verification. 3. Serial number verification: serial number can be verified at efestpower.com + sustained authenticity confirmation. 4. Weight check: authentic Efest 18650 ~45-50g + counterfeits typically lighter (~38-42g) + sustained physical authenticity indicator. 5. Wrap quality: authentic purple PVC wrap features sharp text + clean alignment + uniform colour + counterfeits show poor printing + misaligned text + colour variations. Where counterfeits originate: Unauthorised online marketplaces: third-party sellers on major platforms without UK retailer verification + sustained risk source. Non-UK registered sellers: international sellers without UK Trading Standards monitored compliance + sustained UK consumer protection absence. Unverified dropshippers: middlemen without authentic supply chain + sustained authenticity uncertainty. Common counterfeit signs: unusually low price (~£3-5 per cell vs authentic ~£8-15) + poor packaging + missing holographic + serial fails verification + lighter weight + poor wrap quality. UK retailer authentic supply chain: established UK vape retailers source from authorised distributors + sustained authentic supply + sustained UK Trading Standards monitored + sustained UK 18+ verification + sustained customer protection + sustained warranty support + sustained UK Tobacco and Vapes Act 2026 compliance. UK Tobacco and Vapes Act 2026: Royal Assent 29 April 2026 + sustained UK 18+ verification + sustained UK Trading Standards monitored.
