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, 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.
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.
