Review DELTRAN Battery Tender

The Deltran Battery Tender Plus, model number P14017378, is a high-performing battery charger designed to maintain and extend the life of 12-volt lead-acid batteries. This versatile charger is suitable for a wide range of applications, including motorcycles, ATVs, lawn and garden equipment, boats, RVs, and other powersports vehicles.

The Deltran Battery Tender Plus features a three-stage charging system. In the first stage, the charger applies a high charging current to quickly charge the battery. In the second stage, the charger switches to a lower charging current to maintain the battery at 100% charge while preventing overcharging. In the third stage, the charger enters a float charging mode, maintaining the battery at 100% charge indefinitely. This three-stage charging process ensures that the battery is always in optimal condition, preventing sulfation and extending the battery's lifespan.

One of the most notable features of the Deltran Battery Tender Plus is its patented "maintain" or "trickle charge" mode. This mode provides a small but continuous charge to the battery, ensuring that the battery remains at 100% charge even when not in use for extended periods. This is particularly useful for vehicles that are not used frequently, as it prevents the battery from discharging and ensures that it is always ready to be used.

The Deltran Battery Tender Plus is also highly portable, with a compact design that makes it easy to transport and use in a variety of locations. It comes with a convenient carrying case, and its small size makes it easy to store when not in use. The charger also features a floating voltage regulator, which ensures that the battery is not overcharged or undercharged, even during periods of temperature extremes.

Another useful feature of the Deltran Battery Tender Plus is its automatic recharging circuit. This feature allows the charger to automatically recharge the battery if the voltage drops below a certain level, ensuring that the battery is always fully charged and ready to use. The charger also comes with a reverse polarity protection feature, which prevents damage to the battery or the charger in the event of incorrect connection.

Overall, the Deltran Battery Tender Plus, model number P14017378, is an excellent choice for anyone looking for a reliable and versatile battery charger. Its three-stage charging system, maintain mode, and automatic recharging circuit ensure that the battery is always in optimal condition, while its compact design and portability make it easy to use in a variety of locations. Whether you're maintaining a motorcycle battery, charging the battery of an RV, or keeping the battery of a boat in good condition, the Deltran Battery Tender Plus is an essential tool for anyone who relies on lead-acid batteries to power their vehicles and equipment.
