A battery maintainer, often referred to as a battery charger, delivers a small amount of power to the battery and is used to keep the battery in an optimal state of charge for an extended period of time.
Battery maintainers typically use trickle or float charging, a slow charge that provides enough constant energy to offset the natural energy loss of the battery as it is stored. Charge rates are usually under 2 amps to keep the battery healthy, and in some cases pulse mode applies a high-intensity electrical pulse to help break down the sulfation of the lead-acid battery. When the proper level is reached, the battery maintainer shuts off and there is no risk of overcharging. The use of a battery maintainer will allow the battery to remain inactive for extended periods of time while keeping the battery fully charged, ensuring that the vehicle can be started efficiently when needed, and will help to prolong the life of the battery, preventing it from being damaged by storage.
Batteries drain their capacity when not in use, mainly because they are self-discharging and have a parasitic drain.
As long as there is a load connected to the battery, the load connected to the battery will always consume power when we don’t need to use the vehicle. If you don’t maintain the battery cells or use a battery maintainer, the battery will be drained. There is also the storage of batteries for long periods of time, the batteries, due to their chemical nature, will constantly lose power, resulting in the vehicle will fail to start, and in severe cases, the battery life will be reduced. In order to avoid the situation when we can store the battery for a long time, it is necessary to use a battery maintainer.
4.1 Battery chargers are used to charge batteries when they are dead or depleted, while battery maintainers are not designed for fast charging, but to keep the batteries at the optimal level.
4.2 Battery maintainers prevent overcharging, battery chargers require human intervention.
4.3 Battery maintainers have a lower charging rate and battery chargers have a higher charging rate than battery maintainers
5.1 Consider the battery voltage, the voltage of the battery maintainer must be the same as the output voltage of the battery.
5.2 Consider the battery current, the general battery maintainer current is 2 amps or less, you need to ask the maintenance personnel.
5.3 Select a battery maintainer that is compatible with the chemistry of the battery
6.1 Check the appearance of the battery for dents or protrusions, cracks or crazing, foreign objects or contamination, which may affect the life of the battery.
6.2 Check whether the parameter specifications of the battery maintainer are compatible with the battery.
6.3 Check the appearance of the charger for corrosion, etc. Corrosion of the charger may also result in failure to charge.
6.4 Check whether the battery maintainer wire has broken or damaged phenomenon, there is damage will occur leakage or can not charge fault.
6.5 Check the battery maintainer clamps, clamps with foreign objects can also lead to poor contact or can not charge.
6.6 Connect the positive terminal of the battery maintainer to the positive terminal of the battery and the black negative terminal to the negative terminal of the battery.
6.7 The maintainer will automatically monitor the battery’s state of charge and provide a trickle charge as needed.
6.8 If the battery is in storage, keep it connected.
6.9 When not in use, disconnect the battery maintainer negative terminal then disconnect the battery maintainer positive terminal.
