Why a trailer jack needs charge support

EQ Systems hydraulic pumps are not light loads: EQ Systems recommends load testing the battery, which should deliver a minimum of 150 amperes at a minimum of 10.5 VDC for at least 30 seconds. A trailer battery that has sat for weeks will often run a jack part way and stall, which reads as a pump fault when it is a power fault.

The AJ series

AJ jacks lift 8,000 lbs single and 16,000 lbs dual, with a 24 inch stroke on a 3.5 by 3.5 inch tube. Manual override is standard on both, so a flat battery never leaves you stranded, but it does mean driving the override with a drill.

Other ways to keep the battery up

If the trailer is regularly connected to a tow vehicle, Stay Charge parts 8400 and 8427 charge the trailer battery from the vehicle instead.
