A battery charger will do this by pushing an electric current through it. Various types of rechargeable batteries will require different charge currents, which are supplied from the battery charger, therefore many different kinds of battery chargers are manufactured to supply this need. For example a battery from a motorcycle, will require a different current than a mobile phone battery.
Battery chargers vary a great deal in intelligence, the types of batteries they can charge, how they maintain batteries, and how long they take to charge. As batteries are such a big investment when it comes to off grid solar power systems, it's important to get the right one for your off grid solar power system.
A general rule of thumb is to charge a battery at about 10% of its amp hour capacity. For example, and 80Ah deep cycle battery should be changed at a rate of about 8A.
Different types of batteries require different charging regimes. For example, SLA (sealed lead acid), AGM (absorbent glass matt) and gel batteries are traditionally charged at a lower voltage than flooded lead acid batteries. This varies depending on the manufacturer and you should always check what charging voltage is required before you buy batteries and a battery charger.
There are many different types of chargers and some of these can include:
o Trickle charger
o Fast charger
o Inductive charger
o Solar charger
o Pulse charger
o Intelligent charger
A trickle charger is a device that charges a battery slowly at the self discharge rate, and is the slowest type of battery charger. A battery can be left on a trickle charger indefinitely, and by doing so it keeps the battery topped up but never over-charges it.
Solar chargers use solar energy and they are usually portable. Many portable chargers can only take energy from the sun.
Inductive chargers make use of electromagnetic induction to charge batteries. This is achieved by a charging station sending electromagnetic energy through inductive coupling to an electrical device, which stores the energy in the batteries. This is achieved without the need for metal contacts between the charger and the battery.
