Review OPTIMATE High Performance Battery Charger

The Optimate TM409 is a high-performance battery charger designed for maintaining and charging 12-volt lead-acid batteries, including sealed, absorbed glass mat (AGM), gel, and flooded types. This versatile charger offers several advanced features to ensure optimal battery performance and longevity.

The TM409 employs a microprocessor-controlled, multi-stage charging algorithm. It begins with a bulk charging stage to quickly charge the battery up to 80% of its capacity. Following this, the charger enters an absorption stage, where it maintains the voltage at the optimal level while delivering additional charge to the battery. In the final flooding stage, the charger ensures that all active materials in the battery plates are fully saturated with water to prevent sulfation and prolong battery life.

One of the standout features of the Optimate TM409 is its ability to detect and recover deeply discharged batteries. This charger can revive batteries with as little as 1 volt of charge remaining, making it an excellent choice for vehicles that are seldom used or left unattended for extended periods.

Another remarkable feature of the TM409 is its temperature compensation. This charger adjusts its charging algorithm based on the ambient temperature, ensuring that the battery is charged efficiently and safely, regardless of the environmental conditions.

The TM409 also includes reverse polarity protection, ensuring user safety by preventing the charger from being connected incorrectly. Additionally, it has short circuit protection and overcharge protection to safeguard the battery from potential damage.

This compact and lightweight battery charger comes with a convenient carry handle and a built-in carrying strap. It also features an LED indicator display, which shows the charging status and alerts the user of any fault conditions.

In summary, the Optimate TM409 high-performance battery charger is a versatile and reliable solution for maintaining and charging 12-volt lead-acid batteries. Its advanced features, including temperature compensation, deeply discharged battery recovery, and multiple safety protections, make it an excellent choice for various applications, from everyday use to long-term storage.
