What is a fully charged battery?

A fully charged battery is a rechargeable battery that has reached its maximum capacity for holding electrical energy. It means that the power storage of the battery has filled up to its highest limit, and it can not hold more electrical energy. You can use a fully charged battery for several applications until it undergoes depletion again.

Different batteries have different capacities for storing electrical energy. In other words, each battery is designed with a specific power storage capacity.

How do I know a battery is fully charged?

As we discussed earlier, a fully charged battery is the one that has been charged to its highest level. Like other electronic devices, the battery of the motorcycles must be fully charged for its appropriate functioning. Less charging directly means less working of the motorcycle. A fully charged 60v 30ah lithium battery should read 67.2 volts.

You can use a voltmeter to check the voltage of your motorcycle battery. If the voltage does not lie between the standard limit, your battery is not fully charged and requires further charging. Besides this, different manufacturers have specific guidelines for checking the motorcycle battery voltage. You must follow these instructions to check the exact voltage and prevent any damage to the battery.


Should lithium batteries be 100% charged?

Lithium batteries are different from the traditional batteries when it comes to complete charging. Lithium-ion batteries are allowed to charge to 100% fully charged battery, but must avoid overcharging; full charge needs to stop immediately.

If the charger does not have an automatic power-off function, paying attention to the battery charging process is recommended. No need to wait until the battery is fully charged to 100%. Charging the battery to about 90% is also fine. To extend the battery life, you must comply with the principle of shallow charging and shallow discharge.

Overcharging lithium batteries can cause severe damage and reduce their lifespan. In rare cases, it may also cause an explosion and bursting of the battery if the battery quality is bad. Therefore, you must prevent deep discharges to ensure the prolonged working of the lithium batteries.

Is it wrong to leave batteries fully charged?

Continuously charging a fully charged battery for a long time can cause irreversible damage to the battery. Each battery is designed in a way that it has specific charged and discharged cycles. You can lose battery performance if you charge them beyond their specific limit.

Even if you continue to charge the fully charged battery in trickle mode, some chargers risk malfunctioning if used for too long. In short, charging the battery for a long time will be detrimental to the battery. Leave fully charged battery can also lead to excessive heat generation, adversely affecting the battery’s health.

The prolonged generation of the heat can cause swelling or reduce the overall lifespan of the batteries. Therefore, one should avoid overcharging of batteries. It is best to choose a battery with a battery management system with overcharge and over-discharge protection. Reduce damage to the battery and increase safety.


How many volts is overcharging?

Overcharging of lithium-ion batteries often happens when the voltage surpasses 4.2 volts per cell. The charge cutoff voltage for the Tycorun 48V motorcycle swap battery pack is 58.8V. The charge cutoff voltage for a Tycorun 72v 60ah lithium battery is 86V. If the fully charged battery is at this voltage, the battery is overcharged.

If fully charged battery has a battery management system (BMS), utilize it or a voltmeter to check for overcharging. Always follow the manufacturer’s instructions while charging a battery to guarantee life and safety.

What is a suitable battery voltage after charging?

The optimal voltage of the batteries varies depending on their types. Different batteries show varying voltage after charging. For Example, an excellent 12V battery has a voltage of 14V after charging. Check the battery condition if the battery voltage is higher than 14 volts after charging. If the battery is too low, the battery is not charged.

Similarly, the voltage of the ternary lithium battery reaches 4.2 volts per cell once it is fully charged. It indicates that the battery is healthy and shows exceptional performance. If it doesn’t reach the average voltage after fully charging, it might lose its voltage-storing capacity and have a reduced lifespan.


How can I charge my battery without overcharging?

Charging the battery without overcharging is compulsory to ensure the longevity and appropriate performance of the battery. Here are a few guidelines that you must follow to charge your battery without overcharging.

  • Charge your battery with the correct charger specifically designed to meet the specifications of your battery. It must also fulfill its voltage requirements.
  • Try to use the intelligent charger equipped with the auto-stop charging system. You can also go for the intelligent chargers. Such chargers prevent overcharging by monitoring the battery state and regulating the charging process.
  • The best way to prevent overcharging is to remove your charger once your device is fully charged. Removing the charger will automatically prevent overcharging.
  • You can prevent overcharging by regularly checking the voltage of your battery. Once our battery reaches the demanded voltage, remove the charger.

Smart charging system in Tycorun battery swap station

Tycorun battery swapping stations are using advanced technology with innovative charging systems. We have specialized auto-stop charging systems that stop charging after the battery is fully charged. Thus, you don’t need to worry about degradation and bursting of your battery due to overcharging.

We welcome you to experience the battery swapping technology of our battery swap stations. We assure you you will enjoy the best life experience due to our surprising auto-stop charging systems. It will maintain the voltage capacity of your battery and its cycle life, allowing its long-term functioning.



If your battery dies after unplugging the charger, it means that your battery has lost its charge-holding capacity. Such batteries may be faulty or degrade over time. It indicates that you need to replace your battery with a new one.

If a quality battery is not able to start your electric two-wheeler, you need to see if the battery connection is intact and effective, as well as other motorcycle components such as the motor, you can consult the motorcycle seller.

Yes, you can completely recharge a fully discharged or dead battery. However, some battery types might face issues, such as recharging after death. You must choose the correct charger and follow the manufacturer's guidelines for appropriate battery recharging.
