![]() at trade fairs, vehicle premieres, museums or businesses with regular public tours or demonstrations for customers. Showroom chargers are used in addition to the dealership in all situations where the on-board electronics need to function when the engine is switched off, e.g. Ideally, they are small and unobtrusive and are stowed in the engine compartment or under the vehicle like the DEFA showroom chargers. They supply smaller consumers directly with power and charge the battery as required. Showroom chargers are permanently connected to the mains and the battery. Consumers such as lights, cockpit displays and multimedia devices require power here during every demonstration, even every time the doors are opened, even though the car is not running, i.e. They protect the battery while customers are test-seating the vehicle in the dealership. Showroom chargers are ideal for car dealers. a starter battery in a classic car that is only driven in summer or a small supply battery for camping.Ĭhargers like the DEFA Smartcharge get by with just one button, determine all the technical details independently and show the status of the charging process via LEDs or a display.Ĭonsumer chargers can be used for starter batteries with 6, 12 or 24 volts in all private and commercial vehicles. They allow quick charging in between or when the battery is stored for a longer period of time before it is used again, e.g. ![]() User chargers or consumer chargers are particularly easy to use and easy to maintain. When buying a charger, the most important thing is that it fits the intended use.Ī charger that you use to fully charge your motorcycle battery from time to time has to meet different requirements than one that charges your industrial truck several times a day or keeps the demonstration cars in your car dealership under power without putting a load on the installed starter battery. So choosing the right charger for your battery will ensure that the battery is always properly charged and will help to ensure that its life is not compromised. How well a charger recognises all these factors, evaluates them and adjusts the charging process accordingly influences its charging efficiency. The temperature of the battery and its environment also affects how much current it can hold, as does its discharge rate. When selecting voltage and amperage, the time available to charge the battery plays a role. Different battery technologies such as GEL, AGM or lithium require different charging procedures or charging characteristics. ![]() The charge controller in the charger decides how much current and voltage are charged and in which sequence, i.e. To do this, it provides the battery with voltage (in volts) and current (in amps). In principle, the charger reverses the chemical process that provides the current output in the charged battery. But even here, an imbalance and gradual drop in the state of charge can occur and charging with a charger becomes necessary to protect the battery from premature ageing. There are chargers for this purpose.įor starter batteries, charging is normally done by the alternator.
