Battery Charger

According to the principle, battery chargers can be roughly divided into two types, one is the charger made of iron core transformer. The other is a charger manufactured with a switching power supply.

Early automotive batteries did not have high requirements for charging and discharging. The charging voltage requirements were not strict, and the charging current did not need to be accurately controlled. Therefore, most of the battery chargers at that time were based on iron core transformers and did not have a voltage regulator function. The charger with switching power supply has no iron core transformer inside, but a switching power supply board. Therefore, it is small in size and light in weight, but the charging current is small (only 4 amp), and the applicable battery capacity is relatively small.

With the rapid development of charging technology, new battery charger combines the advantages of the above two. It features built-in pure copper transformers, wide input voltages (AC 100V~240V, 50/60Hz), automatic charging current identification and high charging efficiency.

The best battery charger has so many features and benefits as follows:

1. The battery charger will automatically determine the battery type and voltage specification (12V or 24V) to select the appropriate charging current for charging.
2. All the battery voltage, current, level, type, and other charging parameters will display on the LCD screen.
3. The car battery charger has a segmented charging mode:
   • Constant current mode
   • Constant voltage mode
   • Floating charge mode
   • Full charging stop mode
4. Various protection functions:
   • Overcharge protection: Prevent battery overcharging.
   • Low voltage protection: If the battery voltage is too low, the charger will not start.
   • Overvoltage protection: Prevent battery discharge voltage is too high when charging
   • Reverse connection protection: Positive and negative reverse connection alarm, remove the reverse connection and release the alarm
   • Short circuit protection: When the charger is short-circuited, it will automatically protect and stop charging.
   • High-temperature protection: When the charger temperature is too high, it automatically protects and stops charging.
   • Leakage protection: Reliable grounding to prevent safety accidents from electric shock.
5. Battery maintain function: One key to enter the battery repare function.

The new battery chargers can not only charge the car batteries, but also charge the lead-acid batteries of motorcycles, trucks, RVs, forklifts and other agricultural vehicles. The battery types include SLA, AGM, GEL, sealed lead acid battery, dry-charged battery, maintenance-free battery, etc. Even some battery chargers can charge both lead-acid batteries and lithium batteries.
