You get what you pay for, and poverty eats the money... as the saying goes, they know something. Basically, I didn't like them from the start and wanted to do a durability test, but I forgot... after two years, specifically 23 months that were needed for a break, it was as if they didn't exist. It's a shame about the money; it's better to pay almost double and get a reputable brand and company rather than a battery that may or may not last a year. That's my opinion, of course, and there's a chance it might even leak fluids—fortunately, mine only leaked at the terminals and corroded the connectors
