This 1852 maintenance charger is a practical solution for charging and maintaining both 6V and 12V lead-acid batteries. The charger automatically detects the battery voltage and adjusts the charging for safe and efficient charging.

With battery maintenance, charging and repair functions, you can ensure that the battery lasts longer and that voltage and battery status are clearly displayed on the display during use. It delivers a stable charging current of 4A and is designed to withstand use in boats and garages with dust and splash protection.

Suitable battery capacity (Ah): 20-80 Ah Typical applications: Cars, small to medium leisure batteries and motorcycles with larger batteries

Technical information:

• Voltage display and battery indicator
• Zero output (no current when not connected)
• Reverse polarity protection
• Short-circuit protection
• Dust and splash-proof design
• Power cord length: 60 cm
• Charging cable length with crocodile clips: 70 cm

Explanation: For small batteries (under approx. 15 Ah, e.g. scooter or small motorcycle): 4A is a bit too much, so you should preferably use a motorcycle charger of 0.8-1A. For standard car batteries (40-80 Ah), 4A is just right - safe and efficient charging.

For larger batteries (100 Ah+) 4A will still work, but charging will be very slow.

In short: Look at the battery capacity (Ah). Choose a charger with about 10% of the battery's capacity as charging current. The safe maximum for most lead-acid batteries is approx. 20% of the Ah rating. A charger that is too small will result in a very long charging time, while a charger that is too large can damage the battery.

Instructions or tips: Make sure there is good ventilation around the battery during charging. Check that the battery terminals are clean to ensure optimal contact, and that the clips are attached correctly before connecting power. The charger is suitable for maintenance charging during winter storage of boats and leisure vehicles.
