Lead acid batteries typically have coloumbic efficiencies of 85% and energy efficiencies in the order of 70%. Depending on which one of the above problems is of most concern for a particular application, appropriate modifications to the basic battery configuration improve battery performance.
This article describes the technical specifications parameters of lead-acid batteries. This article uses the Eastman Tall Tubular Conventional Battery (lead-acid) specifications as an example. Battery Specified Capacity Test @ 27 °C and 10.5V The most important aspect of a battery is its C-rating.
To ensure that ratings are given in a realistic way, lead-acid batteries have a few parameters on how they get that “AH” rating. In order to get an AH rating, the battery that is being tested has to be drained down to 0 over the course of a specified amount of time.
Characteristic of the open (or vented) lead acid battery is that the small amounts of hydrogen and oxygen produced at the electrodes during battery operation can be vented to the atmosphere through small holes at the top of the battery.
When mixed ready for use in a lead–acid battery, the SG of the diluted sulphuric acid (battery acid) is 1.250 or 1.25 kg per liter. As the battery is charged or discharged, the proportion of acid in the electrolyte changes, so the SG also changes, according to the state of charge of the battery.

However, due to the corrosive nature the elecrolyte, all batteries to some extent introduce an additional maintenance component into a PV system. Lead acid batteries typically have coloumbic efficiencies of 85% and energy efficiencies in the order of 70%.

Technology: Lead-Acid Battery
There are two general types of lead-acid batteries: closed and sealed designs. In closed lead-acid batteries, the electrolyte consists of water-diluted sulphuric acid. These batteries have no gas-tight seal. Due to the electrochemical potentials, water splits into hydrogen and oxygen in a closed lead-acid battery.

Best Practices for Charging and Discharging Sealed Lead-Acid Batteries ...
Sealed lead-acid batteries are rechargeable batteries that use lead and lead oxide as the electrodes and sulfuric acid as the electrolyte. They are called "sealed" because the electrolyte is contained in a gel or absorbed glass mat (AGM), which prevents spills and leaks. Sealed lead-acid batteries are commonly used in many applications, including emergency …
