What does a flashing green light in a Battery Tender mean?

The flashing lights in a battery tender may mean different things, depending on the model that you have. One of those is a dire warning sign - it means that your battery needs to be replaced as soon as possible. This flashing light may also mean that it has detected some problems with your battery, and it will need to recharge for a while before being used again.

In a Battery Tender Junior, the green light indicator presents a different meaning. And these will be explained further below:

Green Light Flashing: When the battery has a green light flashing with the red light is on, it's over 80% charged. It is safe to remove it at this stage. If at all feasible, leave the battery on charge until the green light is solid. When the green light begins to show, it will continue to do so until the battery charger output current falls below the optimum recharge threshold or until the absorption timer runs out.

Green Light: When the green light is lit, your battery charger is on standby mode. This means that it will keep a full charge for when you need to use them again.

Alternating Green and Red lights: This might signal a reverse polarity connection between the charger output cables and the battery, a sulfated battery, or a corroded battery terminal.

Other light indicators for your reference:

Red Light: When the red light is on, it means that your battery charger has started to charge. If you want a faster and more efficient way for charging large-capacity batteries, then this might take a while.

Red Light Flashing: The red flashing light means that the battery is alive and charging. It could also mean that the charging process has failed because no battery is connected or there was a fault with the connections between the charger and the battery.

If you own this Battery Tender Junior, it is best that you are familiar with what the lights and indicators mean. This way, you'll know when to remove your battery from charging and also if there is a problem with it.

You can check jump starter products on Amazon, for example, that comes with jumper cables (that you can use to jump-start your car).

Can you use the Battery Tender on the AGM battery?

The Battery Tender will not provide higher voltage as AGM batteries require more power from a charger which means you might not get all your money's worth out of one.

On a separate note, battery tenders are not appropriate for charging automobile batteries. Because battery tenders provide power output that is too low for bigger batteries, and charging time would be too long, this is the case.
