The production and escape of hydrogen and oxygen gas from a battery cause water loss and water must be regularly replaced in lead acid batteries. Other components of a battery system do not require maintenance as regularly, so water loss can be a significant problem. If the system is in a remote location, checking water loss can add to costs.
However, all these technologies rely on a good quality lead plate to perform to their rated capacity. Therefore, there is a direct correlation between the weight of a battery and its capacity.
