Pallet jacks are essential for efficient material handling and run on rechargeable batteries for portability. Their batteries require proper maintenance regularly, and neglecting battery upkeep can lead to a shortened lifespan and costly replacements.
This blog post explores practical tips to extend the life of your pallet jack batteries. We'll cover crucial aspects like charging routines, storage practices, and troubleshooting common issues. Implementing these strategies will not only save money but also ensure uninterrupted operations.
It is also recommended to watch the following video for valuable insights to maximize your battery's performance and longevity.
Why is Battery Maintenance Important?
Firstly, why should you even bother with maintenance? Well, there are three big reasons:
- First, proper maintenance extends the overall lifespan of your batteries. This means fewer replacements and lower costs.
- Second, a well-maintained battery delivers consistent power, ensuring your pallet jack operates at optimal levels throughout the workday.
- Third, regular maintenance reduces downtime by preventing unexpected battery failures and breakdowns, which can disrupt your operations and impact productivity.
It will help you understand why battery maintenance is important.
Battery Maintenance Tips
Now, let’s move on to some practical tips for maintaining your pallet jack battery.
Tip 1. Avoid Overcharging or Undercharging
Avoid overcharging or undercharging your battery. Both overcharging and undercharging can have detrimental effects on your battery's lifespan. Overcharging can cause overheating, leading to electrolyte loss and potential damage to the battery's internal components. On the other hand, undercharging prevents the battery from reaching its full charge capacity, resulting in reduced runtime and potential sulfation buildup.
Most chargers come with automatic shut-off features, but it's a good habit to monitor the charging process itself.
Tip 2. Avoid Deep Discharges
Deep discharging, or draining your battery beyond its recommended depth of discharge, can significantly shorten its lifespan.
Whether it's a lead-acid or lithium-ion battery for pallet jacks, they should not be discharged below 20% of their capacity.
Tip 3. Use the Compatible Charger
Always use the correct charger. Using an incompatible charger can damage the battery. Make sure to use a charger that matches the battery’s specifications.
You can refer to your pallet jack manufacturer's recommendations to see the required charger specifications, which are designed specifically for your battery type and capacity.
Tip 4. Implement Opportunity Charging
Opportunity charging means charging your battery during short breaks or whenever it's convenient.
So, whenever you have a break or downtime during a shift, take advantage of it to top off the battery. This practice helps maintain a higher state of charge and reduces the risk of deep discharge cycles.
Tip 5. Keep Checking Electrolyte Level (For Flooded Lead-Acid Batteries Only)
If you’re using flooded lead-acid batteries, keep checking the electrolyte level. Ensure it’s always at the right level to avoid damage. Because, low electrolyte levels can lead to sulfation buildup and premature battery failure.
Top up the cells with distilled water when necessary. For specific water refilling instructions, refer to your battery manual.
Tip 6. Perform Equalization Charging (for Lead-Acid Batteries)
Equalization charging is a controlled overcharging process that helps balance the equal charge across all battery cells. This process should be performed periodically, following the manufacturer's recommendations.
However, it's essential to note that equalization charging is only applicable to lead-acid batteries and should not be performed on other battery types.
Tip 7. Do Regular Cleaning
Keep the battery terminals and cable connections clean. Dirt, corrosion, and debris can cause poor electrical connections, leading to charging issues and reduced battery performance. Clean the terminals with a wire brush and apply a thin coating on the battery terminal protector.
Tip 8. Rotate Battery Usage (If You Have Multiple Batteries)
If you have multiple batteries for your pallet jack, rotate their usage to ensure even wear and tear. This practice prevents one battery from being overused while others sit idle, resulting in an imbalanced lifespan among your batteries.
Tip 9. Plan a Regular Maintenance Schedule
Regular checks and maintenance help catch issues early and keep your battery in top shape.
Tip 10. Avoid Exposing Batteries To Excessive Heat Or Cold
Avoid exposing batteries to excessive heat or cold. Extreme temperatures can have a detrimental effect on battery performance and lifespan. High temperatures can accelerate chemical reactions within the battery, leading to increased self-discharge and potential damage. On the other hand, cold temperatures can limit the battery's ability to deliver its full capacity, resulting in reduced runtime.
Tip 11. Battery Age and Replacement
Keep track of the battery's age and plan for replacements as necessary. Because even with the best care, batteries have a limited lifespan and eventually wear out.
Monitor the battery's performance and replace it when it no longer holds an adequate charge or shows signs of degradation, such as decreased run time or difficulty starting the pallet jack.
