Can I use a battery charger as a battery tender?
Considering this, what is the difference between a battery charger and a battery tender?
The difference is smarts. A trickle charger provides a constant current all the time. It does not know whether the battery is charged or discharged. A battery tender is smart.
Similarly, how do you hook up a battery tender to a battery? Place the battery tender aside. Place the red (positive) battery terminal to the positive of the car battery and secure with the adjustable wrench. Place the black (negative) battery terminal to the black negative of the car battery and secure it with the wrench. Make sure the connections are tight and secure.
Similarly, it is asked, how long does it take to charge a battery with a battery tender?
It is not an exact science, since tenders taper off as the battery voltage rises. A completely dead battery should take at least 35-45 hours or more with a Battery Tender Junior (0.75 amps), and 20-30 with a Battery Tender Plus (1.25 amps). Unfortunately, these chargers cannot begin to charge a fully depleted battery.
What does a battery tender do?
It's a device that plugs into a standard AC outlet and transfers power in the form of amps to your 12 V battery to keep it operational over long periods of inactivity. Battery Tender battery chargers are essential if you have seasonal vehicles that sit for months without being used.
