Technology is one of the oldest and the most mature of all the rechargeable technologies available.
Prismatic or rectangular shape lead acid batteries are manufactured by many suppliers and they vary in the chemical composition as well as rating in regard to high discharge versus general category where low but continuous current is needed from the battery. Due to variance in the chemical composition and the thickness of the plates (electrodes) even the same size batteries will not perform the same way. A Lead acid battery may be recharged using either a constant voltage (CV) charger or a constant current (CC) charging system, or a modification of either or both of these. Constant voltage charging, where a single voltage level is applied across the battery terminals, is the most suitable method to recharge lead acid batteries. To avoid thermal runaway in warmer temperatures, and to improve charge acceptance in colder temperatures, the charger voltage should be compensated by approximately 3 millivolts per cell per degree Centigrade variance from 25A°C. In rush or the initial current applied to a discharged battery will have to follow the manufacturers specifications.
Since not all of the charge returned is accepted to replenish the electrochemical potential, a good rule of thumb to use is that the charge returned should be 105% to 110% of the capacity delivered on the previous discharge.
Never disassemble the cell as the electrolyte is strong alkaline liquid and can harm and damage your skin and clothes. Do not solder directly on the battery as the heat will damage the safety mechanism of the cell as well as it will deteriorate it.

Depending on the CV charger's current limit, it is possible to recharge these batteries from a 100% discharged condition to better than 95% state of charge in a very quick manner. This is a negative coefficient, with the voltage being lowered as the temperature increases, and vice versa.
There is no need to limit the inrush current to the battery during the initial phase of constant voltage charging.
Even if discharge of the battery is stopped before voltage decreases to such a level that the battery driven equipment stops being operational, deterioration of the battery may be accelerated by the so-called sulphation phenomenon if it is not recharged after use. Charging with an unspecified charger or a specified charger which has been modified or tempered with can also cause the batteries to swell or rupture. In some cases gases emitting from the cells would likely to generate pressure which needs to be released. Packaging should be the same as what is found in a retail store, unless the item is handmade or was packaged by the manufacturer in non-retail packaging, such as an unprinted box or plastic bag. Import charges previously quoted are subject to change if you increase you maximum bid amount.


The low voltage cut-off circuit should be designed so that it can completely cut off the discharge current including a weak current.
Also high concentrations on hydrogen may likely ignite if it is close to heat or igniter source. If you reside in an EU member state besides UK, import VAT on this purchase is not recoverable.
Unlike gel cell batteries that use a gelled electrolyte, AGM batteries still use the common water/acid electrolyte mixture, just like regular flooded cell batteries (such as the one in your car). The difference is that AGM batteries have fiberglass matting sandwiched in between the lead plates.
One is the matting prevents the electrolyte from sloshing around and spilling out in case the battery is inverted or put on its side. Another is that the plates can be made with a purer lead (which is softer and needs extra support) that permits higher efficiency. A flooded cell battery does not have this feature and typically the hydrogen and oxygen simply vent into the atmosphere. Over time this causes the electrolyte level to drop, thus preventing the battery from attaining full charge. Contrary to common belief, you actually can maintain these types of batteries, it just is not very common and the manufacturers would rather you didn't for a number of reasons. It is actually very easy to do as long as you are not squeamish about partially tearing your batteries apart.
