Conduct durability tests and keep running with the battery: the lifespan of a typical lithium forklift battery is ten years. Try to choose products from well-known manufacturers and go to regular stores to avoid buying refurbished batteries

In fact, as long as it is a new battery, it is almost the same. The key is to pay attention to points in future use in order to extend its service life. The following are some maintenance methods for batteries:

1. The battery should be securely installed on an electric forklift to prevent vibration damage to the battery during cycling.

2. Regularly remove dust and dirt from the battery cover, and pay attention to keeping the battery dry and clean to prevent it from discharging on its own.

3. Never leave the battery in a state of low charge for a long time, and cultivate a good habit of charging the battery every night.

4. When starting an electric forklift, use a foot pedal to assist in starting, in order to avoid excessive discharge current and damage to the battery.

5. When cycling, be careful not to let the battery discharge. Overdischarge can easily cause serious battery depletion, greatly shortening its service life. Electric forklifts are generally equipped with undervoltage protection function. When only one indicator light on the battery level display is on, the battery should be charged immediately to avoid over discharging.

Identification of battery quality issues

When consumers choose batteries, they first need to check whether the outer packaging of the electric vehicle battery is damaged or has any signs of disassembly. Then, open the packaging to check the appearance of the lithium battery, see if there are any scratches or scratches on the surface, and then check if there is rust on the metal terminals of the positive and negative electrodes of the battery; (For example, the new Tianneng Big Black Bull battery, the original Tianneng Big Black Bull battery has Li Chen's image photo printed on the outer packaging, product batch number, etc.).

The issue of battery life

According to statistics, the lifespan of a forklift's lithium battery is not only related to the quality of the manufacturer's lithium battery products and the system configuration of the electric vehicle, but also to daily maintenance and consumer use. You can also try it out yourself. Taking a 500 watt electric vehicle with a 48 volt motor as an example, if you suddenly accelerate while riding after being fully charged, and the battery gauge needle only falls less than half a grid, it is a new battery; If the battery gauge needle falls one grid, it is a semi new or old battery; If the power meter needle falls 2-3 grids, it is a discarded old battery that is about to be scrapped; If it exceeds four grids, it is basically a scrapped battery.

New and old batteries cannot be strung together for use

According to experts, original new batteries are packaged and shipped after assembly during production. If used together with old batteries, it can affect the performance of the new batteries and cause premature aging of the new batteries! This greatly reduces the service life of the battery.

How to determine a faulty battery

How to troubleshoot a faulty battery? We first fully charge the electric vehicle, let it sit for a few hours or ride for a while, and measure its voltage at the charging plug. Whether it is a new or old battery, if it is measured to be 48V or slightly higher, it is a normal battery; If it can only reach 46V or below, it indicates that a certain battery has a short circuit; If the display shows that the entire set of 10V batteries is faulty

The most convenient way is to use the resistance wire of the electric stove to clamp the positive and negative electrodes of the battery after series connection. Then, use a multimeter to measure the voltage of each battery. If conditions permit, special instruments can be used to view the voltage difference of each battery. Generally, the battery needs to be replaced when the maximum and minimum voltage difference is 6V. Please accept!

Forklift lithium batteries generally refer to lithium batteries used in electric forklifts, which serve to provide power for electric vehicles. At present, the most widely used is valve controlled sealed lithium batteries, because lithium batteries have low cost and high cost-effectiveness. Other types include nickel hydrogen batteries, nickel cadmium batteries, lithium-ion batteries, polymer lithium batteries, and so on.

1. Judging by the appearance of the battery:

Actually, this is very easy to judge. Generally, once you hold it, you can check its appearance to see if there are any scratches or scratches

Check for rust marks on the metal parts of the positive and negative electrodes of the battery.

2. Use professional voltage measurement tools to determine if there is an internal short circuit (broken battery) in the battery:

After cycling for a while or standing still for several hours after charging, measure the voltage at the charging plug and it will be

48 volts or slightly higher is a normal battery (regardless of old or new). If it can only reach 46 volts or below, it means there is one

Each battery has a short circuit (a 48 volt car has four sets of batteries, each consisting of six 2-volt batteries connected in series to form 12 volts), indicating

The 10 volt group is a faulty battery.

3. Determine scrapped batteries:

1) After being fully charged, if you suddenly accelerate while cycling, the battery gauge needle will only drop less than half a grid (one small scale),

It's a new battery.

2) After being fully charged, if you suddenly accelerate your ride and the battery indicator drops one grid, it becomes a semi new or old battery.

3) After being fully charged, if you suddenly accelerate while cycling and the battery gauge needle drops 2-3 grids, it is considered to be quickly scrapped

Old batteries (will self discharge and run out even if fully charged for half a month without riding).

4) After being fully charged, if you suddenly accelerate and ride more than four grids, the battery will be scrapped. (Fully charged for one week)

Riding, electricity will self discharge and run out.

The above are some simple methods for judging the authenticity of electric vehicle batteries that we will talk about today.
