How do I know if my battery tender jr is working?

With the tender connected, and in a charge mode (check its lights to see what it is doing), the battery’s voltage should increase to above 13 Volts, over a period of 5-10 minutes, as this indicates it is being charged by the tender, similar to what the alternator does in the bike, running down the road.

How long does a battery tender take to charge?

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. They need to sense a certain amount of voltage before they can function.

When does battery tender plus go into storage mode?

If the battery voltage does not reach 14.5 volts within 72 hours, then the Battery Tender plus will also go into storage mode. Red light keeps flashing. Green light turns on quickly at the beginning of the charge cycle.

How to know if my Battery Tender is fully charged?

Why do you need a battery tender in your car?

Battery tenders are your ultimate saviors specially in winters when headlights, wipers, and heater are running most of the time. These tenders not only provide continuous voltage to the battery terminals but also make use of spark free technology for security.

What happens when a battery is in bulk charge mode?

If the battery is below a certain level of charge, it will activate bulk charge mode, delivering its full charge at a constant rate. Once a certain level is reached, the Battery Tender ® will activate absorption mode, dropping the amps to a lower level for a predetermined period of time or until the optimum voltage level has been reached.

How to troubleshoot a battery tender plus battery?

(A 12 volt battery may not recover from a discharge this deep.) Disconnect all loads from battery (or battery from vehicle), then reattach Battery Tender PLUS. Wait no more than 3 seconds for solid red light. 2 Charger is not properly connected to the battery: rings or clamps are hooked up backwards.
