A no-nonsense replacement for weak lawn tractor batteries

The Problem Usually Shows Up When You Actually Need The Mower.

The grass is already getting long. The mower sat for a while. You turn the key and instead of a strong start, you get a weak click, slow crank, or nothing at all.

That’s when a cheap replacement battery stops feeling cheap. Now you’re losing time, dragging out the charger, checking connections, or making another trip to buy another battery.

Most people do not want a complicated battery project. They want the mower to start, the install to be clean, and the battery to be ready when the job needs to get done.

That is exactly why the BRS Super-Charged U1 AGM Battery was built around a simple idea: make the replacement process easier, cleaner and more dependable.

Why homeowners switch to AGM

A Better Replacement Than The Basic Flooded Battery Sitting On The Shelf.

A conventional flooded battery can work. But for seasonal equipment that sits, vibrates, and gets used hard when the weather finally turns, sealed AGM is a cleaner and more practical choice.

300 CCA starting power

Strong cranking power for lawn tractors, mowers, generators and compatible utility equipment.

Sealed AGM design

No water top-ups, no acid to pour, and no messy activation at home.

Holds charge longer during storage

Low self-discharge AGM chemistry helps keep the battery ready between seasons.

Built for real equipment use

AGM construction resists bumps and vibration common in ride-on mowers and utility equipment.

“The best mower battery is the one you don’t have to think about every time you turn the key.”

Important: This is a standard Group U1 battery. It is not compatible with U1R applications. Confirm polarity before ordering.

Check before you buy

Make Sure Standard U1 Is The Right Fit.

The battery is simple. The one thing you do not want to get wrong is polarity. U1 and U1R are reversed.

Measure your tray

Compare your current battery space to 7.8″ × 5.1″ × 7.2″.

Confirm standard U1 polarity

This product is standard U1 only, not U1R.

Check cable reach and hold-down clearance

Make sure your cables and strap line up before ordering.

Off-Season Battery Protection

Most People Leave Their Tractor Sitting All Winter.

That is when a good battery can slowly lose charge. If it sits low for too long, it can get weaker before the next mowing season even starts.

The BRS Super Charger BRS612 is a 6V/12V smart trickle charger, battery maintainer and rejuvenator built to keep batteries topped off during the off-season.

Leave it connected during storageMaintenance mode helps keep the battery topped off while your tractor, mower, generator or powersport equipment sits.

Automatic smart chargingBulk, absorption and float charging helps prevent overcharging and keeps the battery maintained properly.

Simple winter habitInstall the ring-terminal pigtail once, plug in the maintainer before storage, and give the battery a better chance of being ready in spring.

If your equipment sits for weeks or months at a time, the maintainer is the simple add-on that helps protect your battery investment.
