Just because you're choosing a used forklift battery, this doesn't mean you have to make a sacrifice in the area of lifespan. You can purchase a used battery from a place like U.S. Lift & Warehouse Equipment Inc and keep it for some time. However, this is only the case when you are focusing on maintenance. Make sure you know how to take care of your battery to keep it in good condition, longer.
Regularly Check Water Level
Make it a habit to regularly check the water level inside the battery. When the water level is too low inside the battery, this can cause it to fail so it is imperative that the proper amount of water be maintained.
Each battery is different, but the minimum water level required should be clearly labeled on the battery's housing. However, generally, the rule is that the battery element should at least be covered with water for proper function and protection. To stay on top of this, make it a practice to check the water level before each use.
Avoid Constant Charging
It would seem like a great idea to keep the battery on the charger when it is not in use so that it is always fully charged. However, this practice will only damage the battery. Understand that the more you charge your battery, the more wear you actually cause so infrequent charging is often the better practice.
To avoid this, it's best to only charge the battery when it is low, instead of constantly charging it. With this method, you will still have a usable battery, but also one with a longer lifespan.
Store In The Right Environment
Ensure you are storing the battery in the right environment. Sure, forklifts can be used in just about any type of environment. However, using the forklift for a short period is a lot different from storing the battery for a long period. This is especially the case when it comes to extreme heat.
High heat levels can damage the internal connections within the battery, causing it to fail prematurely. Make sure you are storing the battery in a space with a moderate temperature, such as a space that is climate controlled which might mean you have to store the battery away from the forklift.
The more effort you put into taking care of the battery, the more use you will get from it and most importantly, the more you will get from your investment. Make sure you are making an effort in this area.
