The period from the initiation of charging to the onset of gassing is known as “bulk charge,” during which charge is returned to a battery at high efficiency. Charging a lead-acid battery normally does not generate hydrogen and oxygen gas until the battery nears full charge, typically at about 90% of its capacity.
Lead–acid batteries may be flooded or sealed valve-regulated (VRLA) types and the grids may be in the form of flat pasted plates or tubular plates. The various constructions have different technical performance and can be adapted to particular duty cycles. Batteries with tubular plates offer long deep cycle lives.
The battery might never be charged back to 100% of its rated value. The most common applications for intermittent charging are in renewable energy such as wind and solar. When the renewable energy source is available (such as the sun during the day or on a windy day), the battery is charged.
The behaviour of Li-ion and lead–acid batteries is different and there are likely to be duty cycles where one technology is favoured but in a network with a variety of requirements it is likely that batteries with different technologies may be used in order to achieve the optimum balance between short and longer term storage needs. 6.
The lead–acid batteries are both tubular types, one flooded with lead-plated expanded copper mesh negative grids and the other a VRLA battery with gelled electrolyte. The flooded battery has a power capability of 1.2 MW and a capacity of 1.4 MWh and the VRLA battery a power capability of 0.8 MW and a capacity of 0.8 MWh.
In all cases the positive electrode is the same as in a conventional lead–acid battery. Lead–acid batteries may be flooded or sealed valve-regulated (VRLA) types and the grids may be in the form of flat pasted plates or tubular plates. The various constructions have different technical performance and can be adapted to particular duty cycles.

A practical understanding of lead acid batteries
So many lead acid batteries are ''murdered'' because they are left connected (accidentally) to a power ''drain''. Charging a lead acid battery. No matter the size, lead acid batteries are relatively slow to charge. It may take around 8 - 12 hours to fully charge a battery from fully depleted. It''s not possible to just dump a lot of current into them and charge them …
