Why fake Efest batteries are dangerous
Counterfeit Efest batteries pose serious safety risk because they use lower-grade cells with unknown chemistry + unknown CDR rating + sustained increased thermal runaway risk. Lower-grade cell sourcing: counterfeiters source cheapest available lithium-ion cells (often C-bin or D-bin reject cells from original manufacturers + or no-brand Chinese factory cells with unknown chemistry) + sustained reduced quality control + sustained unknown actual CDR rating + sustained unknown thermal stability vs sustained quality controlled genuine Efest cells. Unknown chemistry risk: genuine Efest IMR (LiMn) + Hybrid INR (Li-NMC) chemistry sustained known thermal stability vs counterfeit cells with potentially older ICR (Lithium Cobalt Oxide) chemistry + sustained increased thermal runaway risk + sustained increased fire propagation risk + sustained vape mod safety risk. Inflated CDR fraud: counterfeiters often print same CDR specifications as genuine Efest (e.g., 35A) but actual cells may have ~5-10A real CDR + sustained massive overdraw risk when used at marketed wattage + sustained thermal runaway + venting + fire risk + sustained sub-ohm vape mod danger + sustained importance of established UK retailer sourcing. Sub-ohm vape mod abuse risk: counterfeit cells used in sub-ohm vape mod at expected genuine CDR levels = sustained current overdraw beyond actual cell capability + sustained thermal runaway + venting + fire + sustained risk to user + property + sustained importance of authenticity verification before sub-ohm vape mod use. UK consumer protection scope: counterfeit batteries from non-UK-Trading-Standards-monitored sources lack UK consumer protection + sustained no warranty + sustained no replacement under Consumer Rights Act 2015 + sustained no recourse if battery fails + sustained importance of UK retailer sourcing for sustained UK consumer protection. UK TPD compliant. For battery safety detail see are Efest batteries safe.
