polymer lithium battery

　　Why is the polymer lithium battery damaged and how to remove it?

　　Damage to the polymer lithium battery may be caused by incorrect charging operations, incorrect water replenishment processes, using the wrong charger, etc. In addition, the steps to disassemble the battery are to first loosen the negative connector nut, then disassemble the negative connector, remove the positive connector, Disassemble the locking strap, and I will introduce the relevant content in detail below.

　　1. Five factors that damage car batteries

　　1. Wrong charging operation

　　Charge at the operator's convenience. A charging plan should be set up when installing the battery system, as different facilities require different types of charging systems. Such as battery replacement, opportunity charging or fast charging.

　　All batteries have a limited number of charge cycles before battery capacity begins to decrease. For most industrial batteries, this is generally around 1,500 charge cycles, which equates to about 5 years of regular use. Setting up a charge schedule for your battery can extend its life, saving a lot of money.

　　2. Wrong hydration process

　　Replenish water before battery is fully charged. It may overflow and remove some of the sulfuric acid, thereby removing the electrolyte balance specific gravity. This will cause the voltage to go awry, and if this process is repeated, the battery will degrade significantly.

　　The correct time to add water is once every 1-3 weeks, depending on many factors: temperature, type of utilization. It is important to set up routine checks to monitor the water level in your forklift battery.

　　3. Use the wrong charger

　　The charger is too big or too small. This usually damages the battery because chargers are specifically designed to work with batteries of a specific size and capacity.

　　Use outdated technology. Such as mechanical chargers (iron and SCR). These chargers can cause the battery to overheat, consume more water, and increase the temperature of the battery, damaging the battery over time. The cumulative result is a significant reduction in battery life.

　　4. Charging and working temperatures are unreasonable

　　The temperature is too high or too low. The optimal operating temperature for lead-acid batteries is 30 to 90 degrees Fahrenheit. If it is higher or lower than this range, it will have an adverse effect on the battery.

　　The ideal temperature range for charging forklift batteries is typically 50-86 degrees Fahrenheit. If your forklift operates and charges in extreme temperatures, you should work with an application engineer to design a battery charging system that better meets these needs.

　　5. Too many or too few batteries

　　In a competitive environment, where the unit cost per pallet is increasingly important, having multiple batteries on hand is an expensive way to operate. Charging algorithms can be used to handle these needs more efficiently and ensure you have the appropriate number of batteries.

　　2. How to disassemble the polymer lithium battery

　　1. Loosen the nut of the negative electrode connector: Open the two fixing buttons of the insulation cotton, and you can see the two red and black insulation covers on the positive and negative electrode connectors. Open the insulation cover and you can see the locking nut;

　　2. Disassemble the negative electrode connector: Use a wrench or hex socket to unscrew the fastening nut of the negative electrode, then use a flat-blade screwdriver to slowly pry open the fastening block, and then pull out the negative electrode connector;

　　3. Disassemble the positive connector: Use the same method to disassemble the positive connector;

　　4. Disassemble the locking strap: Unscrew the nut used to fix the battery's locking strap, loosen the locking strap, and then take out the battery.

　　5. When installing a new battery, just follow the reverse steps. However, it should be noted that the order of installing the positive and negative connectors is "positive first, then negative", which is opposite to that of disassembly. The principle is the same, both to prevent the risk of short circuit and ensure safety.
