Overview

Every motorcycle battery gradually loses charge when left unused.

Alarm systems, clocks and modern electronics all place a small drain on the battery, while cold weather accelerates deterioration.

The OptiMate 4 has earned an outstanding reputation because it doesn’t simply recharge a battery—it continuously monitors its condition, adjusts the charging programme automatically and safely maintains the battery for months if required.

It’s designed for riders who want to keep their motorcycle ready to ride all year round.

---

Build Quality

The first thing you’ll notice is how well made the OptiMate feels.

The charger is housed in a durable weather-resistant casing with clear LED status indicators that make it easy to understand exactly what the charger is doing.

The supplied cables are substantial, connectors feel secure and everything gives the impression of a quality product built to last.

It’s immediately obvious this isn’t a budget charger.

---

Installation & Ease of Use

Setting up the OptiMate 4 is refreshingly simple.

The kit includes:

• Permanent fused battery lead.
• Crocodile clip lead.
• Weatherproof connector system.
• Clear instructions.

Most owners permanently fit the battery lead to the motorcycle, allowing the charger to be connected in seconds whenever the bike is parked.

Once connected, everything else happens automatically.

There’s no need to select charging modes or monitor progress.

---

Performance

This is where the OptiMate 4 really stands out.

Rather than simply supplying a constant charge, it automatically works through several charging and testing stages.

These include:

• Battery assessment.
• Controlled charging.
• Voltage testing.
• Maintenance charging.
• Long-term battery monitoring.

If a battery has been deeply discharged, the recovery programme may even restore batteries that cheaper chargers would simply reject.

While it can’t work miracles on a physically damaged battery, it often succeeds in recovering batteries that owners assumed needed replacing.

---

Everyday Ownership

The OptiMate is particularly valuable for riders who:

• Store motorcycles over winter.
• Own several motorcycles.
• Only ride occasionally.
• Use seasonal bikes.
• Keep a motorcycle in a garage for extended periods.

Instead of wondering whether the bike will start after several weeks, owners can simply disconnect the charger and ride away.

---

Value for Money

At first glance, the OptiMate 4 costs noticeably more than many basic trickle chargers.

However, replacing a quality motorcycle battery can be expensive.

If the charger extends the life of even one battery, it has already paid for much of its purchase price.

For riders planning to keep their motorcycle for several years, it’s an investment rather than an expense.

It’s easy to install, virtually foolproof to use and built to a standard that inspires confidence.

Although it costs more than many entry-level chargers, its intelligent charging technology and long-term reliability make it money well spent.
