What equipment is the SuperCharge MFU1 designed for?
MFU1 is a compact U1/GU1 mower battery for ride-on mowers, garden tractors and small plant that specify a U1 case. Always check tray size, hold-down and cable reach before purchase.
How is MFU1 different from MFU1R?
They’re similar in performance; the difference is terminal orientation. MFU1 uses the standard U1 layout, while MFU1R is reverse-polarity (U1R). Choose the version that matches your cable routing.
What are the MFU1 dimensions and terminal type?
Approx. 196 × 128 × 159 mm (L × W × H), total height ~184 mm. Case code U1/GU1 with top-stud, Offset Lug Terminal (OLT) posts. Confirm terminal clearances and clamp style before installing.
Is the MFU1 maintenance-free?
Yes. It’s a sealed maintenance-free (SMF calcium) starting battery—no routine topping up. Keep terminals clean and tight, and maintain charge if the mower is stored.
What are the cranking and capacity ratings?
Typical ratings are about 350 CCA and 35 Ah (20-hour rate), providing reliable starts for correctly sized ride-on mowers and garden equipment.
Can I use MFU1 for deep-cycle loads (lights, pumps)?
MFU1 is a starting battery intended for short, high-current cranking. For frequent deep discharges, choose a dedicated deep-cycle battery.
How should I charge MFU1 during off-season storage?
Use a compatible 12 V smart charger with lead-acid/Calcium mode and maintenance (float). If not on a maintainer, top up every 4–6 weeks to reduce sulphation.
Does Archer Batteries offer installation and testing?
Yes. Buy online or in-store and we can install MFU1, verify charging voltage, and dispose of your old battery responsibly.
What’s the warranty on MFU1?
18-month warranty (conditions apply). Keep your proof of purchase and ensure the mower’s charging system is within specification.
How do I confirm polarity before connecting the battery?
With the battery label facing you, identify the + (red) and – (black) cables and confirm they reach the matching posts on a U1 layout. Never rely on memory—check markings on both cables and battery.
