5 Best Activation Methods For Dead Lifepo4 Lithium Batteries

5 Best Activation Methods For Lifepo4 Lithium Battery, it is not necessary to charge the new lifepo4 lithium batteries for 10 hours to activate the battery activity, it can be activated according to the normal charging and discharging method.

Regarding the "activation" problem of lifepo4 lithium batteries, there are many sayings: the charging time must be more than 12 hours, and it must be repeated three times in order to activate the battery. This statement that "the first three charges should be charged for more than 12 hours" is obviously a continuation of the statement from nickel batteries (such as nickel-cadmium and nickel-metal hydride). Therefore, this statement can be said to be misrepresented from the beginning.

The charging and discharging characteristics of lifepo4 lithium batteries and nickel batteries are very different. All official technical documents emphasize that overcharging and overdischarging will cause huge damage to lifepo4 lithium batteries, especially liquid lithium-ion batteries. Therefore, it is best to charge the lifepo4 lithium batteries according to the standard time and standard method, especially not to charge for more than 12 hours. Usually, using the charging method described in the lifepo4 lithium batteries manufacturer's operating instructions is the standard charging method.

In fact, shallow discharge and shallow charge are more beneficial to lifepo4 lithium batteries.

Only when the power module of the product is calibrated for lifepo4 lithium batteries, is it necessary to discharge deeply and charge deeply. Therefore, products powered by lithium batteries do not have to stick to the process, everything is convenient, and they can be charged at any time without worrying about affecting their lifespan.

Activation Methods For dead Lifepo4 Lithium Batteries

The following activation methods are available for: RV battery (recreational vehicle) / marine / golf cart / scooter / solar storage / agm & amr/ electric vehicles, motorcycles, balance bikes, unicycles

Dead batteries refer to batteries that are not charged for a long time, the charger does not respond when recharged, and there is no charging current measured with a multimeter, even if the battery is charged for a long time, it still cannot be used.

Here are 5 better methods that can save most of the "starve" lifepo4 lithium batteries. Note that it is mostly, not 100%.

1. Activation dead Lifepo4 Lithium Batteries Methods 1: Tandem Method

Connect a normal voltage 12 volt battery in series with the entire battery pack.

For example, if the original car is a 48V-20AH battery, then we will connect another 12V-20AH battery in series. A 12V battery with sufficient power has a voltage of about 13V. After connecting in series, the voltage of the entire battery can be increased, and then the battery manufacturer's original charger can be used to charge it. After the charger is plugged in, the charger indicator is red, and it has Charge normally. When the indicator light of the charger turns green, you can remove the battery connected in series, and then charge it normally.

2. Activation dead Lifepo4 Lithium Batteries Methods 2: Parallel Method

This method is a little more cumbersome.

For example, the marine was originally a 48V-20AH battery, and we also connected a group of 48V-20AH batteries in parallel. The voltage across the parallel circuit is equal, and the higher voltage side will flow into the lower voltage side. This method is also used by many battery dealers to detect batteries that are completely dead. Then charging can also achieve the purpose of charging. This principle is similar to that of connecting a battery in series. It also increases the voltage of the entire group.

3. Activation dead Lifepo4 Lithium Batteries Methods 3: Low voltage charging method

Use a charger with a low voltage for charging. For example, it is a set of 60V-20AH batteries, then we use a 48V-20AH charger for charging. In most cases, it can also be charged. The principle is also similar to the first activation method, bringing the charging voltage closer to the voltage across the battery.

4. Activation dead Lifepo4 Lithium Batteries Methods 4: Single battery charging method

Charging a single battery with a 12-volt motorcycle charger can activate the battery, but this charging is relatively slow. Generally, it takes more than 7 hours for the battery voltage to slowly rise to about 12V. It takes time to charge all single blocks.

5. Activation dead Lifepo4 Lithium Batteries Methods 5: Special Charger Method

The universal charger automatically recognizes the battery voltage. No matter how many volts the battery voltage is, it can automatically recognize the voltage, and he can charge it. For example, the marine is a 60V-20AH battery, and now there is only less than 30V, it can still be charged inside. As the voltage increases, it fully adapts to a higher-order voltage, and then charges the battery.
