Heagstat HEAG055 is much more than a charger. It has a microcomputer chip, is lightweight, compact and fully automatic, that digitally controls the 8-stages of battery charging(as follows). Rated at 5.5-amp for all types of lead-acid and lithium-ion batteries, including flooded, GEL, and AGM, as well as, marine and deep-cycle batteries.
Other names: battery charger, lithium battery charger, lifepo4 charger, 12v lithium charger, car battery charger, trickle charger, trickle charger for 12 volt batteries, battery charger automotive, battery maintainer, 6v 12v battery charger, 6v 12 volt battery charger, auto battery charger, agm battery charger, deep cycle battery charger, motorcycle battery charger, car battery maintainer, automotive battery charger, motorcycle charger for battery, battery charger for cars, automatic battery charger, trickel battery charger automotive, trickle charger for car, trickle charger for car battery, trickle charger for motorcycle battery, trickle charger 12v, trickle charger 6v, trickle charger for motorcycle, and more.
DESULPHATION: Detects sulfated batteries, pulsing current and voltage, removes sulfate from the lead plates of the battery restoring the battery capacity (Only available in lead-acid battery mode).
Specification:
- Input: 100-120VAC 50/60Hz 90W Max.
- Battery voltage: 6V, 12V
- Charging current: 2A, 5.5A DC
- Suitable battery type: Lead-Acid (AGM/GEL) and Lithium (LiFePO4)
- Winter mode: Yes
- Multi-stage charging: 8-Stages
- Protections: Spark proof, reverse polarity, short-circuit, overcharging, over temperature and IP65 water-resistant
- Charging battery: 6 - 150Ah
- Maintaining battery: 6 - 200Ah
ATTENTION: This unit is only suitable for one type of lithium battery, It is 12V Lithium(LiFePO4) only, Other types of lithium battery does not support.

8-STAGES CHARGING CHARACTERISTIC:
- BATTERY TEST (Lamp 1): After connecting to the power supply, press Mode button to select appropriate battery charging mode. After connecting to battery, the charger will automatically detect the battery performance. In normal status, the battery will enter stage 2 in 4 seconds. 6V and 12V lead-acid batteries lower than 3.5V or 12V lithium batteries lower than 4V are invalid and beyond handling.
- DESULPHATION: Detects sulfated batteries. Pulsing current and voltage, removes sulfate from the lead plates of the battery restoring the battery capacity (Only available in lead-acid battery mode).
- SOFT START: Initial battery test to determine battery condition. If the battery is severely discharged, the charger will begin the Soft Start stage. Charging starts with reduced current until the battery voltage reaches a normal charge.
- BULK: Major charging stage where the battery receives the majority of its charge. During this stage the battery is brought up to 75-80% of its charge. The battery charger delivers maximum current until the terminal voltage has risen to full charge level for normal battery.
- ABSORPTION: Completes the charge up to virtually 100% at a constant voltage. The current tapers off when the current reaches the minimum level.
- ANALYSIS: Tests if the battery can hold charge. Batteries that can not hold charge may need to be replaced(Fault LED is solid red), Only available in lead-acid battery mode.
- FLOAT: Low constant voltage, minimal charge current, battery is fully charged.
- PULSE: Maintaining the battery at 95-100% capacity. The charger monitors the battery voltage and gives a pulse when necessary to keep the battery fully charged (Only available in lead-acid battery mode).


EASY TO USE
This smart car battery charger has a very simple operation design, so very easy to use.
- Firstly, Connect the AC power supply.
- Secondly, Choose the right charging mode.
- At Last, Correct connect the battery.
IMPORTANT: When you select the battery mode, You must disconnect the battery.
