12V Lead-Acid AGM Charger for 2-90Ah Batteries
This automatic charger handles 12V lead-acid batteries including WET, MF, AGM and GEL types from 2 to 90Ah capacity. It features an LCD display and full protection systems for safe operation. The unit suits cars, boats, RVs, trucks, motorcycles and snowmobiles. It is designed for users who need a set-and-forget charging solution.
Verify your battery is 12V lead-acid between 2
Check that your battery chemistry matches WET, MF, AGM or GEL types before connecting. Ensure the input supply is 120V 60Hz mains power. Confirm the battery voltage is 12V, not 6V, for the primary charging mode. The charger will not suit lithium or other chemistries outside the stated range.

Interchangeable lead sets let you switch between alligator clips and ring terminals for permanent or temporary connections. The LCD indicator shows charging status and protection alerts including reverse connection, over-charge and short-circuit warnings.

Questions about this item
Does the package include both the alligator clips and the ring terminals, or must I buy one set separately?
The charger ships with detachable, interchangeable lead sets that provide both pole clamps and ring terminals, so no extra cables are required.
How do I decide between the 6 V and 12 V output settings for my battery?
Match the setting to the battery's nominal voltage — use 6 V for a 6 V battery and 12 V for a 12 V battery; the unit supports both ranges.
What does the 3.8 A maximum charging current mean for a 90 Ah AGM battery in practice?
At 3.8 A the charger will take roughly a full day to bring a deeply discharged 90 Ah battery back to usable capacity, with automatic stage control and full protection.
