Battery Tender

I ordered the Battery Tender 3 amp. It is well worth the price. There are days that the car just sits there and this is the answer to a dead battery. It keeps it charge charged by trickling voltage to it. It helps if you have an electrical outlet in your garage. It was well packaged and shipped, and arrived on time. It certainly puts Walmart right up there with Amazon, especially with the free shipping.

Very highly recommended

I have been using this brand for decades. They are always reliable and anytime I've ever had an issue. They replaced it free of charge and told me to keep the one I had. This particular one I got because I drive a 7.3 L diesel, which uses two batteries so this particular one will charge my battery a little quicker than the 800 mA model. Walmart is the least expensive source that I have been able to find for the battery tender brand.

Pretty Good Battery Tender

Very simple to use. Not complicated! Full power for charging quickly, and a "smart charger" for long-term maintenance. Important! Detailed instructions, which you should read first before using the battery tender.
