Is LiFePO4 battery life affected by the number of times the battery is charged?

Does the number of battery charges affect the life of the LiFePO4 battery (Lithium iron phosphate battery)? We all know that the cycle life of lead-acid batteries is about 300 times, and the maximum is 500 times. However, the cycle life of LiFePO4 batteries can reach more than 2,000 times, and it can reach 2,000 times after standard charging (5-hour rate). The lead-acid battery of the same quality is “new half-year, old half-year, maintenance half year”, at most 1~1.5 years, while the theoretical life of LiFePO4 battery under the same conditions will reach 7~8 years, in this case, many LiFePO4 battery users have doubts. They will ask whether the number of charging times of the LiFePO4 battery has an impact on the life of the LiFePO4 battery. Today, the LiFePO4 battery manufacturer Grepow will interpret the LiFePO4 battery for everyone. Does the number of charging times affect the life of LiFePO4 batteries?

Does the number of charging times of the LiFePO4 battery affect the battery life?

The life of a lithium battery decreases with the number of charges. Lithium battery charging times are generally 2000-3000 times. After doing so many cycles, the power storage capacity of the lithium battery will decrease to a certain extent. For example, in lithium batteries, the nominal charge-discharge cycle is “not less than 60% of the nominal capacity after 500 cycles”, that is, after 500 cycles, the battery can only store 60% of the new battery’s power, which means that the performance has a certain degree of Decline. Therefore, when using a lithium battery, it should be charged in time, and do not wait until it is out of power before charging. This is not good, and it is right to charge it frequently.

The number of charging times of LiFePO4 batteries will affect the battery life, because the life of lithium batteries is generally 300-500 charging cycles, and the number of charging times is one of the indicators to measure the life of LiFePO4 batteries. The life of a lithium battery is about 1000 times. However, the charging time is deep charging and discharging, and the shallow filling is incomplete. The use of LiFePO4 batteries does not need to be so tangled. If the battery affects the use, please replace it with a new one.

When we use batteries, we also need to pay attention to the effective recycling of batteries, and protecting the environment is the responsibility of all of us.

The charging method of LiFePO4 battery

Lithium rechargeable batteries have been widely used, and LiFePO4 batteries have been used more and more because of their unique advantages. The chargers of LiFePO4 batteries are different from ordinary lithium batteries.

  1. Some cell phone chargers are protected, they stop charging when the voltage of the lithium battery reaches 4.2 volts. A slightly higher power silicon diode (forward voltage drop of about 0.6V) is connected in series between the LiFePO4 battery and the charger. When the battery voltage of LiFePO4 reaches 3.6V and the diode voltage drop is just 4.2V, it can also be detected by the charger and stop charging.
  2. The mobile phone battery protection circuit is taken out for charging protection of LiFePO4 battery. When charging, a diode is connected in series according to the above principle, which plays a protective role of 4.2 volts.

There is no fixed limit on the number of times the battery can be charged by LiFePO4. The LiFePO4 battery produced by regular LiFePO4 battery manufacturers can be charged and discharged at least 500 times, and the capacity remains above 80% of the initial capacity. It can be used once a day for 2 years. Under normal circumstances, the mobile phone battery is charged 1000 times, which will cause the battery to not be durable. Therefore, whether it is a lithium battery or a LiFePO4 battery, the more charging times, the better.
