Are the Batteries Exchanged for Old Ones Refurbished Batteries?

Battery is refurbished. Here is the relevant content introduction: Battery refurbishment: Battery refurbishment has formed a complete industrial chain. After processes such as water replenishment, desulfurization, softening repair, opening the case to replace plates, capacity restoration, and polishing, a set of scrapped old batteries can be transformed into a set of brand-new batteries. Regular manufacturers: Generally, when purchasing batteries from regular manufacturers, the products are bought at the price of new ones, with a 15-month warranty period. If you buy refurbished batteries from small workshops, the quality is not guaranteed, and the service life is very short. The value of the exchanged old battery is about one-third of that of a new battery.

I also pondered this when replacing my car battery last year. The trade-in program essentially means merchants recycle old batteries for a discount, but the replacement you get usually isn't refurbished. Authorized shops provide brand-new batteries in original factory packaging with clear anti-counterfeit codes and manufacturing dates. Old batteries are recycled by manufacturers—lead plates are recast, electrolytes are processed—making it both eco-friendly and economical. Of course, be wary of small roadside shops that may pass off refurbished batteries as new by polishing the casing to look pristine. Remember two things: check the warranty period (genuine new batteries come with at least two years of coverage) and verify the anti-counterfeit label. I ended up choosing an authorized brand store—got ¥80 off for my old battery, and the new one still delivers strong power today, starting the engine crisply every time.

Having worked in auto repair for over a decade, I deal with battery trade-in services daily. Simply put, reliable dealers provide essentially brand-new batteries, while the old ones are taken back mainly for lead and plastic recycling. Refurbished batteries mostly come from unofficial channels, where old batteries are repackaged in new casings and sold as new—these have shorter lifespans and are prone to leakage. How to tell the difference? Here’s a quick tip: genuine new batteries have blue anti-oxidation film on the terminals, with smooth, scratch-free electrodes. Price is also a clue—if a battery is more than a third cheaper than others of the same capacity, be wary. Every new battery I handle is weighed and tested for internal resistance before installation. My advice: watch the unpacking when replacing a battery and note the production batch number.
