#Car battery charger heavy duty full

We considered charger-maintainers that trickle-charge a battery to full charge and then maintain the battery charge indefinitely (for weeks or months) without damage. Most will charge and then maintain six- and 12-volt car batteries. The modern maintainers will turn on and off to avoid overcharging. Traditional battery trickle chargers can only supply a constant charge. Read on to learn about five of the best options on the market today. There are also six-volt and 12-volt units, depending on your needs. The most affordable modern chargers can cost as little as $30 and some cost as much as $100. Where there was once a simple green light to let you know a battery was charged, now there are multiple sensors and functions, plus LED monitors. They can also detect weak batteries and automatically cut power if the user crosses the battery cables. Plug one in and forget it for a day, a week or the entire season. They’ve evolved to smart, microprocessor-controlled battery charger-maintainers that turn on and off to avoid overcharging. They only provide a constant current to the battery, which requires a car owner to monitor the charger and the vehicle. Traditional trickle chargers connect a set of wires to your battery and charge at a steady rate. Nothing kills a car battery quicker than when a car sits for weeks and months on end. But when you don’t, especially if a vehicle stays outside in the cold, the battery will drain. When you drive a vehicle every day, its battery stays at a constant state of charge.
