What equipment is the SuperCharge MFU1R designed for?
MFU1R is a compact reverse-polarity U1R mower battery for ride-on mowers, garden tractors and small plant that specify a U1R case. Always check tray size, hold-down and cable reach before purchase.
What’s the difference between MFU1 and MFU1R?
Performance is similar; the key difference is terminal orientation. MFU1 uses the standard U1 layout, while MFU1R mirrors the posts (reverse polarity) to suit mowers wired the other way. Choose the version that matches your cable routing.
What are the MFU1R dimensions and terminal type?
Approx. 196 × 128 × 159 mm (L × W × H), total height ~184 mm. Case code U1R with top-stud, Offset Lug Terminal (OLT) posts. Confirm terminal clearances and clamp style before installing.
Is the MFU1R 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 around 350 CCA and 35 Ah (20-hour rate), providing reliable starts for correctly sized ride-on mowers and garden equipment.
Can I use MFU1R for deep-cycle loads?
MFU1R is a starting battery intended for short, high-current cranking. For frequent deep discharges, choose a dedicated deep-cycle battery.
How should I charge the MFU1R 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 MFU1R, verify charging voltage, and dispose of your old battery responsibly.
What’s the warranty on MFU1R?
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 U1R layout. Never rely on memory—check markings on both cables and battery.
Is the MFU1R spill-resistant and sealed?
Yes. It’s a sealed maintenance-free design for typical mower orientations. Always keep upright during transport and follow standard safety precautions.
Can Archer Batteries recycle my old mower battery?
Absolutely. We accept spent lead-acid batteries for safe recycling. Drop it in when collecting your new MFU1R or during installation.
