How many years could lead-acid battery of forklift be used?
We usually think it is 2-3years.
Whether it’s an electric forklift seller or an expert in forklift maintenance, it’s basically like this.
In terms of reality, if your battery is discarded after 2 to 3 years, you are likely to suffer a greater economic loss. This is why?
Scientifically speaking, the service life of a forklift battery cannot be measured by the length of time. What is the measurement? It should be the number of charging and discharging.
The current mainstream forklift battery design life is generally 1600 cycles. When this standard is reached, the battery charge capacity will drop below 80% of the factory setting, and it will need to be replaced.So how can there be a relatively uniform service life in time in this case? Therefore, the judgment of the service life of 2 to 3 years is only a rough estimate, and it is not scientific.
Having said that, everyone should understand that how to judge the service life of a battery is not based on the number of years, but based on the number of charge and discharge cycles.
The frequency and intensity of forklifts used by different companies or individuals will obviously not be uniform. Forklifts in large storage centers or factories will be equipped with backup batteries.When the battery is exhausted, replace the battery directly, change shifts, and the equipment will not stop. The battery is either working or charging and will not stop at all. Without interval replacement, a forklift battery performs an average of 1.7 cycles per day,so 1600÷1.7÷365≈2.6(years)
The service life of the battery under this intensity of use is in line with the statement of 2-3 years, but can the forklift battery of the general small business or individual user be used to this extent?
Just as small enterprise, if the forklift battery is cycled once a day, that is 1600÷1÷365≈4.4（years） , That is to say, if it is used in a charge-discharge cycle once a day, it will take at least 4 years before it can be considered as a hedge.
In other words: instead of working overtime, a forklift battery is only used for 2-3 years, then it means that more than 40% of the value is wasted in vain.Taking a 48V forklift battery with a unit price of about 2w as an example, the net loss per battery is about 8k.
We now know the service life of forklift batteries. Is there any way to scientifically increase its service life?
The service life of forklift batteries is closely related to daily maintenance.
A large number of manufacturers equipped with electric forklifts generally have a dedicated maintenance staff for every 10 vehicles, and there are also dedicated charging stations.A variety of professional maintenance equipment can guarantee the best maintenance of each forklift and each battery, and the battery’s service life can be fully utilized.
It’s just that for individual users, without a certain number of forklifts, the cost of this solution is too high.
So is there a maintenance solution suitable for our individual or small and medium-sized forklift users?
Of course there are.
The average service life of forklift batteries in foreign developed areas is only 4-5 years, and their labor costs are high. Forklift batteries are charged and discharged every day.However, employees have a high awareness of battery maintenance, and the development of supporting industries is relatively mature. There are many battery maintenance “black technologies” that help individuals and small and medium-sized users to perform professional maintenance of batteries.
Lead-acid Battery Liquid level Indicator(Remind operator to add water for battery)
Battery water filling gun(Special water filling tool for lead-acid battery, Be able to balance the liquid level,Full water induction stop)
Battery remote management system(forklift battery management and monitoring system)
Many foreign brands of batteries come with these supporting facilities when they leave the factory, and the staff also have the corresponding maintenance awareness.The performance of the battery is naturally played to the extreme.Large domestic factories have also adopted this set of equipment to achieve 4 years of results.
The good news is that some domestic companies are now paying attention to this market, and the corresponding supporting products are gradually improving. I believe that the service life of domestic forklift batteries will soon be able to catch up.
