What this charger does and who needs it

The BatteryJack inc. 6V 3A SLA charger handles sealed lead-acid batteries at both 6 V and 12 V. It delivers a 3.0 A constant current and uses three-stage smart charging with automatic shutoff. The unit accepts 100 to 240 V AC input at 50 to 60 Hz and includes short-circuit, polarity and over-voltage protections. LED indicators show red while charging and green when the battery is fully charged.

Check your battery and mains supply first

Confirm the battery is a sealed lead-acid type rated for 6 V or 12 V operation. The charger outputs 7.2 to 7.4 V DC for 6 V batteries and 14.3 to 14.7 V DC for 12 V batteries, with float voltages of 6.7 to 6.9 V and 13.5 to 13.8 V respectively. Ensure your local mains supply falls within the 100 to 240 V AC, 50 to 60 Hz range and that you have a compatible AC plug for the 1.0 A input.

Included accessories and their effect

The package contains one charger unit only. No cables, clamps, mounting hardware or software are bundled, so you must supply appropriate battery leads and connectors separately. The charger meets CE standards and measures 120.0 x 60.0 x 38.0 mm. A two-year warranty with free replacement is provided by the manufacturer.
