A battery tender is a device that is perfect for vehicles that are not frequently used. It serves the functions of both a battery charger and a battery maintainer, so you can get two for the price of one when you purchase it. Many people prefer to use these than other kinds of automotive battery chargers, because it lets them save money and effort that would have been spent on battery replacements.
Battery tenders are products that are used to charge batteries and maintain their charge status even when being stored for a specific period of time. They are specially made for the batteries of cars, recreational vehicles, diesel trucks, all-terrain vehicles, and even snowmobiles. Basically, a battery tender can charge a battery at a slow rate, so that users may be able to leave it charging for a given time. Once it is fully charged, it can help maintain the charge level of the battery, because the time required for it to be fully charged is equal to the time for it to be discharged.
Due to the abovementioned reasons, battery tenders offer their users several benefits. First, they are very safe to use. You do not have to worry about the possibility of short circuits even if they let the charger connected to the battery for a long time. Battery tenders maintain the charge amount of the batteries; they do not overcharge when the batteries have reached their fullest. Second, battery tenders can lengthen the life span of batteries. Since they maintain the charge of batteries, you would not have tendencies to store batteries for a long time. When you disconnect batteries from chargers but do not use them, the batteries still lose their charge.
