During the charging process, the reactions at each electrode are reversed; the anode becomes the cathode and the cathode becomes the anode. During charging, given the high voltage, water is dissociated at the two electrodes, and gaseous hydrogen and oxygen products are readily formed leading to the loss of the electrolyte and a potentially explosive situation.
Under certain circumstances the lead sulphate products at both the electrodes achieve an irreversible state, making the recharging process very difficult. Pure lead is too soft to use as a grid material so in general the lead is hardened by the addition of 4 – 6% antimony. The function of the grid is to hold the active material and to conduct electricity between the active material and the battery terminals.
Ball milling: Pieces of lead are put into a rotary mechanical mill, forming fine lead flakes, which are then oxidised in air and removed. Red lead (Pb3O4) can also be added to the PbO formed by these methods, as it is more conductive.
The oxide is mixed with water, sulphuric acid and a mixer, and then mixed to form a paste. The simplest cell would consist of one cathode plate, one anode plate and a separator between them.

Accurately monitoring lead-acid battery state-of-charge would help with the long-term sustainability of off-grid renewable energy systems. There are a number of ready-built products already available, mainly for the recreational vehicle market (eg. This ties in with my open-source charge controller project and also the battery monitor project, which has been on my list of things to do for a number of years.
I have managed to obtain a few samples for various battery monitoring ICs and also found the data sheets for others.
There has been a recent article on the need for monitoring state-of-charge and health of batteries here. These are designed for small portable consumer electronics with Li-Ion technology batteries. He mentions that the shunt resistor from the data sheet is theoretical 30mOhms, and with other shunt resistors different current ranges can be measured, as long as the maximum shunt voltage is <80mV.
The voltage can be measured with a potential divider to keep it within the range of 5.5V max.
There are a number of applications notes relating to this IC "Going to production", "Configuring the Data Flash" and "Using the IC for sealed lead-acid batteries". There are a number of other ICs when you search for 'Battery Monitor IC', but nearly all of them relate to Li-Ion or NiMH technology and are designed for use in small personal products, such as laptops and phones. We are now selling kits that help you monitor and measure the world around you in our NEW shop. Description The Panasonic LC-R127R2PG features membrane technology, so it is completely maintenance-free and unaffected by storage.

The most common is the SLI battery used for motor vehicles for engine Starting, vehicle Lighting and engine Ignition, however it has many other applications (such as communications devices, emergency lighting systems and power tools) due to its cheapness and good performance.
Strips of lead foil with coarse cloth in between were rolled into a spiral and immersed in a 10% solution of sulphuric acid. These act as grain refiners, decreasing the grain size of the lead and thereby increasing its hardness and strength. This is often used for telephone applications, and for no maintenance automotive batteries, since a more stable battery is required. Each droplet reacts with the air to form an oxide layer, giving 70 – 85% lead oxide.

Import charges previously quoted are subject to change if you increase your maximum bid amount. I wanted to review the few that I had heard about and see how applicable they might be for an off-grid battery monitor. While not useful for a large lead-acid battery bank,  this might be useful for some form of small Li-Ion solar lamp.
This can be used to measure power flow and hence calculate the state-of-charge of the battery. Battery monitoring could also be implemented using a microcontroller, which I will also be looking into, but to get a reasonable accuracy then a better resolution ADC would be required (rather than the 10-bit ADC incorporated within most microprocessors. The cell was further developed by initially coating the lead with oxides, then by forming plates of lead oxide by coating an oxide paste onto grids. The molds are closed and filled with sufficient molten lead to fill the mold, leaving some excess to form a sprue, which is then removed by cutting or stamping. The separators are usually cellulose, PVC, rubber, microporous polyethylene or non-woven polypropylene. If you reside in an EU member state besides UK, import VAT on this purchase is not recoverable. But it is only single direction, hence two would be required for correct battery monitoring. However, if a starter battery is discharged deeply (more than 20-25% depth of charge), its plates can be permanently damaged and the lifetime of the battery greatly reduced.
The tabs that are fixed to the plates are cast, then punched on between the layers and welded together.
Deep cycle batteries have fewer thicker lead plates, and so cannot discharge energy so quickly, but can be cycled deeply and recharged many times without damaging the battery. The plates are suspended inside the case, which is filled with electrolyte in order to activate it.
