Key Features of Battery Tender Plus Battery Chargers

Smart Charger Technology

4-step charging includes several stages, depending on the battery level. Some stages provide more power than others, but everything is adjusted automatically based on what's needed.

Fully Automatic Charging

Without any input from you, the Deltran Battery Tender Plus puts itself into the Maintain Mode once the battery receives a full charge. This system ensures that the battery doesn’t get overcharged and damaged.

Battery Status Monitoring

The Battery Tender Plus lights show you the state of the battery. You can easily see if the Battery Tender Plus red light is flashing by looking at the handy LED indicators.

Spark Free Circuitry

The Battery Tender Power Plus3 includes ring terminals and alligator clips that don’t spark when they touch. The model won’t send out voltage until it first recognizes three volts of power coming from the battery.

Quick Disconnect Harness

The Battery Tender Plus 021 0128 offers a quick disconnect feature that cuts down the connection and disconnection time when using your battery charger. Spend less time getting set up with this feature.

Good for Long Term Storage

You can use the Battery Tender Power Plus for batteries that you put in storage. If you want to maintain a charge, simply connect the maintainer to your battery, and don't worry about it. 

Low Maintenance Design

There’s very little you have to do with this Deltran battery maintainer. It is meant to work for many years, without any help from you. There’s even a five-year warranty for more protection.

Reversed Hook Up Protection

With this protection running through the internal circuit, you know that the device won’t get damaged if the power supply polarity becomes reversed. Instead, the circuit cuts power.
