This charger does include a GRAY SB175 connector, if you need other options, check out the link below.

This is an excellent all around battery charger.  It’s compatible with any household outlet (115v / 120v) and can charge at the most popular voltages.  We always keep one of these handy in our shop for rentals because it’s so portable.  It’s also a great charger for heavily discharged batteries that a standard computer controlled charger won’t even try to charge (starts even if the battery is down to 2 volts).

The ChargePlus FLEX is a universal, high frequency, off-board replacement charger programmable for lead-acid (flooded, gel or AGM) batteries and is designed to optimize battery capacity and overall battery longevity. The ChargePlus FLEX is perfect for light-duty equipment such as pallet jacks, scissor lifts, floor care equipment and more!

EASY TO READ LCD DISPLAY
Easy to read, easy to interpret digital display. LED indicators with status screen for quick charge cycle monitor and status. The LCD display of the battery charger displays the battery voltage before starting the charge, then displays the current value (A), the voltage (V), recharged capacity (C) and time elapsed from the start (t).
