鸿贝蓄电池FMJ/BB12200T(12V200Ah)太阳能光伏发电需要2.4KW/h的电量可以充满，如果负载是300W，则这只电池可以供电6-7个小时，太阳能电池在室外使用环境恶劣要注意防护；
Due to the increasing monomer lead-acid battery voltage temperature per 1 ℃ down about the characteristics of 4 mv, then a is composed of six monomer battery series of 12 V battery, 25 ℃ when the float charging voltage of 13.5 V.When the temperature of the environment is reduced to 0 ℃, float charging pressure should be 14.1 V.When the temperature rose to 40 ℃, float charging pressure should be 13.14 V.At the same time, lead-acid battery has another characteristic. When the ambient temperature is fixed and the charging voltage is 100mv higher than the required voltage, the charging current will increase by several times. Therefore, it will lead to thermal runaway and over charge damage of the battery.When the charging voltage is lower than the required voltage of 100mv, the battery will be undercharged and damaged.Lead-acid battery capacity is also related to temperature, temperature is about every 1 ℃, below capacity will fall by 1%, so the manufacturer requirements users of lead-acid batteries battery out 50% of the rated capacity in the summer, winter released after a 25% should charge in a timely manner.
