Inverter Battery Charger with Start-Assist Function Wertberg Smart Start (LG6.69) (Code: LG6.69)

⚡ Inverter Battery Charger–Starter Wertberg LG 6.96 Smart Start

A professional device designed for traditional lead-acid batteries (WET – liquid electrolyte), gel batteries (GEL – gel electrolyte), and AGM batteries (absorbed electrolyte) with a nominal voltage of 12 V and 24 V.

The device accurately, efficiently, and safely restores high battery performance across a wide capacity range. The optimal operating range is from 40 Ah to 800 Ah (smaller batteries can also be effectively charged with lower-power chargers, while larger batteries simply require more charging time).

Equipped with an engine start function for internal combustion engines (petrol and diesel), delivering an effective yet safe starting current of up to 600 A, and allowing precise adjustment of the maximum charging current from 5 A to 90 A.

• Protection against short circuit and reverse polarity with error indication
• Full charge indication and automatic switch to maintenance mode
• Intuitive push-button control, LCD display, and LED indicators
• Easy transport and storage – approx. 70% lighter and smaller than traditional transformer chargers
• Comfortable and durable carrying handle

⚡ Control and Indication

• Charging current adjustment knob – precise current setting
• Buttons: mode selection (charge ↔ start), voltage selection (12 V ↔ 24 V)
• LCD display: actual charging current
• LED indicators: charging mode, connection error, start mode, 12 V mode, 24 V mode

⚡ 4-Stage Charging Cycle

1. Initial charging (battery voltage < 12 V)
2. Constant current charging
3. Constant voltage charging
4. Maintenance charging

During charging, the LED indicator lights red; after full charge, it turns green.
