How to correctly charge a battery?

A battery is an electrochemical device which stores energy in a chemically bonded structure and releases the energy in the form of electrons resulting from the battery’s chemical discharge reactions. Charging the battery provides the electrons to reform the chemical bonds which are stored in the battery’s active materials.

VRLA Batteries – explained.

A Valve Regulated Lead Acid (VRLA) battery differs from a vented battery in that it is sealed using a pressure relief valve which prevents the gases produced on charging from escaping. Keeping the gases in facilitates their recombination to re-form water which is lost on charging due to electrolysis. In order to ensure that the oxygen and hydrogen…

Batteries for Power Plants in Europe

The British company Chloride introduced in the 60es the so-called High performance Plantè battery followed by the other European companies. In Germany the type was called GroE. The cell was characterized by still the Plantè plate for the positive, but a flat plate with a PbSb alloy for the negative. The strap and the pillars were also made in a PbSb alloy.

PVC Battery Separators

An overview of characteristics, manufacture & test methods.

PVC battery separators are microporous diaphragms placed between the negative and positive plates of lead acid batteries to prevent any contact between them to avoid internal short circuit but at the same time allow free circulation of the electrolyte.
