5 Steps for Forklift Battery Maintenance

Posted by Crown Battery on Jun 19, 2015 12:56:00 PM

A common question that's asked is how long does a forklift battery last? And although the average for a single-shift operation is five years, there are cases where forklift batteries have lasted up to ten years. If you're like many others, batteries are a necessary investment, they are essential for daily business operations, but they can come at a hefty cost. 

In order to cut replacement costs and ensure your battery has a long and useful life, regular battery maintenance is necessary! But what is the best way to maintain a forklift battery? Follow these easy steps for proper forklift battery maintenance. 

Charge the Battery Correctly

It can be tempting to charge a battery whenever it is convenient, but the fact is that in order to properly maintain a forklift battery, it should only be charged at certain times and to certain degrees. Charge a forklift's battery only when it dips below 30% charge and be sure to charge it until it is full and then stop charging it. Remember to never interrupt a charge cycle. Additionally, over or undercharging this type of battery can significantly decrease its lifespan

Equalize Batteries Regularly

Flooded or wet cell batteries should be equalized on a regular basis. This process reverses the chemical process of stratification, when the battery acid becomes more concentrated at the bottom of the battery. When the acid and water become stratified, the battery is no longer able to hold a charge as well.

Equalizing rebalances the electrolyte concentration and also helps to remove sulfate crystals from the battery plates. Equalizing can only take place with a battery charger that has an equalizing setting. Many batteries need equalization approximately each five to ten charging cycles, but be sure to check the maintenance specifications for a battery before initiating the process.

Check Fluid Levels

Forklift batteries need to have the right amount of water to work at optimum capacity. Approximately every five charge cycles, be sure to check the forklift battery fluid levels by opening up the battery. Check two to three cells and ensure that there is enough fluid to cover the plastic battery element. If  you are unsure, check all of the cells. If there is not enough fluid upon inspection, move on to the next step and add water.

Maintain Water Levels

If the water levels are not appropriate, you will want to top off the fluid in the battery. This will be necessary approximately every 10 charges. If the battery is brand new, you'll want to add enough water to cover the battery's plastic element protector.

It's important to be aware of how much water your battery needs and how water levels impact your batteries over health and performance. Extra space is needed for the expansion that happens when the battery is in use, which is why overfilling a battery can cause permanent damage. Note that maintenance free batteries do not need to be topped off.

You will only want top off a battery after the battery is fully charged. It is also important to use the right water, which measure between 5 and 7 on the pH scale and is within recommended limits for impurities. Impure water can lead to battery damage.

Keep Batteries at a Safe Temperature

Forklifts can be used in extreme environments, so it is essential to consider the ambient temperature for the battery when in use. Keeping any battery at a safe temperature, where its operating temperature does not exceed 45℃ (113℉), will help to prolong its life. If this is not possible, be sure there is plenty of air circulating in and around the battery compartment for optimal battery cooling.

Even a Crown forklift battery, which are extremely durable and can last for years, need to be subject to proper maintenance in order to extend their lives. Luckily, this maintenance is easy to incorporate into any forklift maintenance routine.
