The Battery Tender Plus 021-0128 is compact in size and simple to use. It comes with different adapters that enabled use with different battery charging requirements. It has a set of adapters that allow you to permanently attach pigtails to the battery posts and then you can quickly connect the tender without having to use the alligator clips (also included).
It’s very small size makes it extremely easy to use and store. And it will not overcharge, so you do not have to babysit the process.
It’s LEDs glow red when charging. Green and red blink once 80% has been achieved. Solid green at 100%.
In environment where the heat and humidity can be just as brutal on batteries as the cold this compact device works well. In very cold weather, it may take a long time to establish a full charge on your almost completely discharged battery. The battery will be usable in a few hours, but 100% can take close to 18.
There isn’t a better charger around for the price than the Battery Tender Plus 021-0128. It’s the granddaddy – and it does the job quickly and well for a very good price. It has two indicator LEDs which show 4 status states (Verifying the battery, charging, charging with battery level over 80%, and fully charged – on trickle charge mode). This makes it easy to see what the charger is doing and when your battery is ready to roll.
The Battery Tender Plus 021-0128 has a robust powder coat painted metal body and a modular plug attachment that allow you to hook up various battery connectors. It comes with two connectors (clips for car and marine batteries and rings for motorcycles).
Battery Tender Plus 021-0128 does everything the high priced models do with the same efficiency, but costs less, and includes accessories at no extra cost.
For the price and free shipping you can’t go wrong!
I highly recommend this “tender” for those that have cars that stay unused for long periods.
