Summary of new technologiesLow-expansion anode materials, all-ear design, electrode surface treatment, flexible electrode molding and other technologies help to solve the liquid intrusion into large batteries and achieve comprehensive safety protection and long life through heat insulation, anti-diffusion, pressure reduction and other methods..
How to choose a battery with the longest life?EVE MB30 Automotive A+ certified batteries are supplied directly by EVE, not through third parties, not through Alibaba, or most retailers and battery manufacturers, including almost all Australian and Chinese batteries, unless they can provide to you a) official. afternoon delivery report for the battery of purchase and b) proof that the QR code is genuine and has not been reprinted with a laser.The B-A level problem gets bigger with the new LF280K v3 (actually MB30)..
