拉脱维亚采购需求：摩托车电池、电动自行车电池、汽车电池、蓄电池、锂电池

I'm looking for a high-performance rechargeable battery with a rated voltage of 12V. Ideally, the capacity should be between 50-55Ah, and dimensions should not exceed 291mm in length, 107mm in width, and 225mm in height. AGM technology is preferred, with front-terminal options available for M6 stud or bolt hole connections. The battery needs to operate effectively in temperatures from -10°C to +50°C and should support constant charge mode. A lifespan of at least 12 years and a warranty period of 3 years are essential. Internal resistance should be ≤ 8mΩ, and the weight should be a minimum of 16kg. I'm interested in an order of 3,570 pieces.
