How Long Does a 40v Lithium Battery Last Per Charge

A 40 volts lithium battery lasts at least forty minutes or more than 40 minutes per charge swinging on the using capacity. This type of battery is more powerful. If it stays in the discharged level for a prolonged period, it is not damaged or dead. Even though the lithium-ion battery chargers are better & more expensive than others. 

Know details? 

This article takes you through a complete guide of how long a lithium battery lasts per charge and more relevant info. So, shall we get the show on the road in the writing?

First, we highlight the main point. Then, discuss other necessary data eventually.

How Long Does a 40 Volt Lithium Battery Last Per Charge?

The charging & discharging cycles of a 40-volt lithium battery is not different from other lithium batteries. Battery lifetime is from 300 to 400  charge cycles or up to 2000 charging as well as discharging cycles. Most lithium-ion batteries can provide services long-term within one full charge. There is no specific time to continue the charge. But, the mower’s lithium-ion battery lasts at least 40 minutes per charge. 

So, when it is on a full charge, you can use it for up to 40 or 50 minutes as well. Remember that lithium batteries take usually 60 to 120 minutes to charge ( Depending on the voltage). No worries, they charge fast. Before using, you should check the manufacturer guidelines. 

How Long Does a Lithium Battery Hold its Charge When in Use?

The charging cycle is the period of use from fully charged to discharged. Even fully recharged again. The general life of a Lithium-Ion battery exists from two to three years or 300 to 500 charge cycles. When you use it, the charge level can be reduced. A lithium battery can hold its charge for more than one hour. 

Is it OK to Leave a Lithium-ion Battery on the Charger?

Though it is fine and perfect for leaving the lithium battery discharged after a long period, it is important to charge them as needed. Due to the low maintenance charging system, users can leave the lithium-ion battery without changing it. 

The short answer is that it is not OK to leave your lithium-ion battery on the charger although tool instructions announce to stock the battery on the charger. As an intelligent user, you should discard the charger when charging is finished. 

Otherwise, the battery can damage and get a shortened life just because of overcharging. Believe it or not, all chargers are not shut off automatically. The charging level – 0% is empty and 100% is full charge. So, when your lithium battery is 100% charged, remove the charger as soon as possible.

How Do You Store Lithium-ion Batteries When Not in Use?

Storing lithium-ion batteries is not a rough process. These batteries can take hold of charging for a lot of time. So, when not in use you can store it with confidence. The best way is to store it with a full charge. In other words, if you store a lithium-ion battery with less than 20% charge or very low charge, it can be dead. Because low charge goes through the lower level after a long time. Then the battery requires charge again for safety lifespan.

A great idea, don’t leave or store the lithium battery for many months. Better yet to take it out sometime and use it. Then charge the battery fully again and leave it.

Now the question is where to store a lithium-ion battery.

Store batteries in a room with a dry climate and ventilated. You have to restrain the storage area from heat, humidity, or sunlight. Maintain a steady temperature like around 59 degrees Fahrenheit. The excellent battery storage temperature is not too high or low, just sufficient room temperatures.

Do Lithium-ion Batteries Go Bad If Not Used?

Lithium-ion batteries have special circuitry that helps to keep them damage-free against overcharged or undercharged problems. For this reason, you can store the battery if you are not used to it. But, don’t forget to check the charging level. 

When lithium-Ion batteries are fully charged, they don’t go bad if not used. These can go bad if you store them in a discharged state. Even though the too low voltage can cause icky chemical reactions. Then, the battery can degrade automatically. Finally, it doesn’t matter if the battery is not 0% charged & not used for many months. 

How Do You Fix a Lithium-ion Battery That Won’t Charge?

Somehow your lithium-ion battery can be slow or not capable of holding the charge at a particular time. You might think to protect this drained battery as soon as possible. It is possible to fix a lithium-ion battery by accomplishing a full recharge. Before going to the process, it is important to keep its charge at an empty level or zero percent. Of course, you apply this procedure only to fully drain batteries. Now, keeping it turns back on if it isn’t ready to boot.

Why Do Lithium Batteries Need a Special Charger?

Each lithium battery requires a sophisticated charger that can be used to monitor the charging process very carefully. Due to their several sizes and shapes, each battery doesn’t allow the other sizes and manufacturer chargers. Just need a special or particular charger to save your battery life. 

Moreover, this type of charger limits the number of currents to reach a pre-set level. At this time, the battery also goes to a preset voltage level. When the battery is charged fully, the current automatic decreases. This charging technique is risk-free of overcharging and charging quickly. 

How Do You Charge a Dead Lithium-ion Battery?

Sometimes you can store a discharged or very low charge lithium-ion battery for prolonged periods. It drops to a sleep mode or dead. To charge a dead battery, you need to collect a special feature charger, known as “boost”. Or, every lithium-ion battery includes a protection circuit charger that is suited to charge any empty level battery. Plug the battery into its special charger. Monitor sometimes. If there is no problem or bad signs, you can continue its charge for maximum capacity.

Wrapping Up 

Finally, we are at the dead-end of the article on how long a 40v  lithium battery lasts per charge. Not only we presented the specific point but other expected factors are highlighted in this writing. So, we covered everything you need- how to store, charge holding capacity, dead lithium battery, how to fix, special charger, etc.

Hopefully, you’ll be smart enough to understand top to bottom as well. Plus, carefully charge your 40v lithium battery and use it for a long period.
