Features: product structure, performance, use and maintenance (MF Series) 1. Strong polypropylene shell, advanced lead-calcium alloy, special lead paste formulations, anti-mist filters, batteries shock resistant 2. Low self-discharge, loss less water, good cold starting performance. 3. The newly purchased without charge, without adding liquid, loading can be used, also without water during use. 4. When in use, the battery should be kept clean to ensure good contact wiring, terminals and connections should be coated with Vaseline at the protective layer, and the battery fixed. 5. If a user deems it necessary to remove the charge, constant current limiting charging method can be used, the maximum current does not exceed 0.2CA, charging voltage is within the range of 14.4 ~ 15V. 6. Battery Store in cool dry place away from direct sunlight, shelf life of more than six months of battery recharged before use at once, charging methods: 0.1CA example: 60Ah battery: 6A Charging 6 hours. 7. This is suitable for charging the battery voltage is less than 14.8V car. Advantages: refer to the product manual Applications: 1.
