The battery tender lights could mean different things, depending on your car’s model. One of those denotes a lousy warning sign. It means that your battery needs to be replaced as soon as possible as it has detected some problems with your battery, which needs to recharge for a while before being used again.
What does a flashing green light on a Battery Tender mean?
The green light in a Battery Tender Junior communicates a different message. This will be discussed in further detail below.
- Green Light Flashing: When the battery tender flashing green light on with the red light, it’s over 80% charged. It is safe to remove it at this stage. If everything is feasible, leave the battery on charge until the green light is solid. When the green light begins to show, it will continue 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 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, your battery charger has started to charge. This might take a while if you want a faster and more efficient way of charging large-capacity batteries.
- Red Light Flashing: The red flashing light means 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.
Is the Battery Tender Junior good for larger engines?
The Battery Tender Junior is small, lightweight, and very affordable. It is great for smaller batteries and cheaper than its counterparts on review. Owners of scooters and motorcycles with small engines should purchase this model. Its quick connect cables can maintain your battery at the optimum charge level.

Can you use a Battery Tender to jumpstart a vehicle?
The Battery Tenders are all intended to be chargers. They don’t include an internal battery that can be used to jumpstart your car. Other devices come in the same product line. You can check jump starter products on Amazon with jumper cables that you can use to jumpstart your vehicle.
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, so you might not get all your money’s worth out of one.
Battery tenders are not appropriate for charging automobile batteries since it provides power output that is too low for bigger batteries. As a result, the charging time would be too long.
If your car experiences an issue, you will be better able to diagnose the problem if you are familiar with the meaning of the green light on your Battery Tender. When purchasing a battery between Tender Junior and Tender Plus, consider assessing your engine size as it has distinct purposes. Remember that replacing batteries involves risks. Thus taking preventive measures before operating the device is very much advised. Carefully read the customized manual for more information.
