NOCO GENIUS1
NOCO GENIUS1 smart trickle charger maintaining a car battery in winter storage to prevent cold-weather failure.

Winter is tough on batteries. The cold slows their performance, while weeks of inactivity can leave them flat and useless. For anyone storing a car, motorbike, or leisure vehicle over the colder months, this is a familiar headache. But this October, NOCO is offering a great deal on a solution so that you can be prepared for when cold weather strikes. During Prime Big Deal Days (7–8 October), you can save 20% on the NOCO GENIUS1 trickle charger, a compact but powerful device that keeps your battery topped up, protected, and ready to go.

Why Cold Weather Leaves Batteries Powerless

Batteries are most vulnerable in freezing temperatures. At 0°C, a fully charged battery provides only around 80% of its normal power. A half-charged one can even freeze overnight, leaving you stranded.

For daily drivers, this can mean an inconvenient breakdown. For those storing motorbikes, classic cars, or caravans during winter, it almost guarantees a flat battery by spring. That's why many motorists invest in a trickle charger for winter. By keeping batteries safely topped up, a NOCO battery maintainer eliminates surprises when it's time to drive again.

The NOCO GENIUS1: More Than a Car Battery Charger

The NOCO GENIUS1 battery charger is an all-in-one charger, maintainer, and restorer, designed to provide long-term protection and reliable performance.

Here's why it stands out:

  • Universal compatibility – Works with 6V and 12V lead-acid and lithium-ion (LiFePO₄) batteries.
  • Multi-vehicle use – Ideal for cars, motorbikes, scooters, mopeds, lawnmowers, quad bikes and more.
  • Smart charging – A built-in thermal sensor adjusts output based on temperature, preventing overcharging or undercharging.
  • Revives flat batteries – Force Mode charges completely dead batteries, even at zero volts.
  • Restores health – Precision pulse charging reverses sulphation and acid stratification, extending lifespan.
  • Safe to leave connected – Can remain plugged in 24/7, making it a perfect battery maintainer for winter storage.

Compact and portable yet rich in advanced features, the NOCO GENIUS1 trickle charger offers unmatched convenience and peace of mind.

A Winter Scenario Every Driver Can Relate To

Picture this: It's a frosty January morning. You scrape ice off your windscreen, turn the key... and nothing happens. The battery is flat. You're late, stranded, and possibly facing the cost of a replacement.

Now picture the same morning with the NOCO GENIUS1 maintainer quietly keeping your battery charged. You turn the key, and your car starts instantly. That's the difference a car battery trickle charger makes, it's invisible protection until the moment you need it most.

Seasonal Vehicles Need Extra Protection

Motorbikes, mopeds, and classic cars often spend months unused in garages. Without a motorbike battery maintainer or car trickle charger, these vehicles slowly lose charge until they're no longer usable.

The GENIUS1 battery charger eliminates that worry. It provides a consistent, intelligent charge so your vehicle is ready for the first warm weekend of spring. For owners of leisure vehicles, scooters, and even lawnmowers, it's just as effective.
