Hart 40V Battery Blinking Blue Light (2024)

FAQs

Why is my battery just blinking blue? ›

Low Battery

However, a blue blinking light can often be a broad indicator that there's an issue with your battery's power. It could be that the blinking will stop and become a different colour, indicating the battery's status. However, it could warn you that your battery is about to die and you must charge it.

Unless it is explicitly disabled, and ETE or ITE are not installed, the blue LED flashes if any of the following are true: Battery Charge is below 10% Battery Life is less than 15%

A 40V lithium battery typically lasts about 30 minutes to an hour per charge, depending on what you're using it for. If you're doing something heavy-duty, like mowing a thick lawn, it might run out closer to the 30-minute mark. For lighter tasks, you might get closer to an hour.

The flashing blue light starts first to show that the PS4 is doing a system check to ensure everything is running smoothly. The issue begins when the PS4 detects a problem while doing the system check. If your PS4 has the blue light of death problem, the blue light will just keep blinking and never turn white.

Battery corrosion looks like a buildup of crumbly or ashy residue, which can be white or blue in color. This is typically visible around your battery's terminals and can be very unsightly. Most times this can be spotted by popping the hood of your car and having a look at your car battery terminals.

A blinking battery light can indicate that it's time to replace your car battery with a new one. Maybe your battery has reached the end of its lifespan or it was damaged. Faulty wiring or bad grounds can also result in a car battery that doesn't hold a charge. The solution is to install a new battery.

A: As in the owner's manual: (1) steady red light = battery charging, (2) blinking red light = bad battery, (3) steady green light = battery charged, (4) blinking green light = battery overheated, remove and let cool before charging. Helpful?

Lithium Batteries:

The 100% GREEN LED will blink indicating the charging process is under way and will continue until the charging process is complete.

These lights will call out attention and warn you that emergency vehicles are on the move. In fact, when you see these lights, it is best to keep your distance or pull over to the side of the road if they can be attributed to an emergency vehicle.

Enabling a blue light filter may have a slight impact on battery life, but the effect is generally minimal. The additional processing required to apply the color overlay is typically optimized to minimize energy consumption.

Does blue light mean fully charged? ›

A: When you begin charging a blue light comes on to let you know it is charging. When the blue light goes off you know that the charging is complete.

All HART 40V Batteries are covered by a 3-year limited warranty.

The number of charging and discharging cycles that your battery goes through will affect its lifespan. Generally, a higher cycle life battery will have a longer lifespan. This is where lithium shines with its 3,000 – 5,000 partial cycles, on average. It's designed to be used for many many years!

A: No, not without intervening circuitry to step down the voltage to 20 volts. You can generally use a higher capacity battery (that is one with more amp hours and thus run time) but the battery itself has to be 20 volts. Higher voltages will destroy the tool.

The charging current is too high or the charger voltage is too high (LED 2 blinks twice per second or LED 3 blinks three times per second). Use the standard provided charger and charging cable to charge the battery. 2. Short circuit detected/internal communication error (LED 2 blinks three times per second).

For example, if you encounter a wireless charger blinking blue, it usually means that there's a fault in the connection.

The Alternator Needs Replacing

If the voltage is less than 12v, it can cause the battery dashboard light to illuminate and blink. The fix is usually to replace the alternator. Your auto mechanic can install a new alternator or replace an alternator belt.

If the LED blinks blue when you plug the battery in the battery has cells that are either under voltage or over voltage.
