How to Change a Forklift Battery: A Step-by-Step Guide from AMP

Changing a forklift battery might sound daunting, but with the right tools and know-how, it’s a task you can tackle confidently. At AMP, we’re all about reliability and empowerment, stocking top-brand batteries and equipment to keep you moving. This guide will walk you through the entire process.

Why Changing a Forklift Battery Matters

A forklift’s battery is its heartbeat. Without a reliable power source, your operations stall, costing time and money. Over time, batteries lose their charge capacity, especially under heavy use. Knowing how to swap one out ensures your machine stays road-ready—or rather, warehouse-ready. AMP stocks trusted brands like Yuasa and Exide, so you’re always equipped with quality you can count on.

Tools You’ll Need to Change a Forklift Battery

Before you begin, gather the essentials. Having the right gear makes the job smoother and safer. Here’s what you’ll need:

• Insulated gloves and safety goggles for protection
• A wrench set to loosen terminals
• A battery lifting tool or hoist for heavy lifting
• A Milwaukee Tools battery brush to clean connections
• A replacement battery from AMP, matched to your forklift model

We’ve sourced the best tools and batteries for you, blending practicality with performance. Check our range at AMP now to find everything in one place.

Step 1: Prepare Your Forklift for the Swap

Safety comes first. Park your forklift on a flat surface and turn it off. Engage the parking brake to keep it steady. Next, disconnect the power by switching off the main breaker or unplugging it from the charger. This simple step prevents shocks and keeps you in control.

Put on your gloves and goggles now. Batteries contain acid, and a slip-up could sting.

Step 2: Locate and Access the Battery Compartment

Every forklift is a bit different, but the battery usually sits under the seat or in a side compartment. Check your manual to pinpoint its spot. Lift the cover or slide out the tray—some models need a gentle nudge, others a quick unlatch. If it’s stuck, don’t force it. 

Once it’s open, take a look. You’ll see the battery secured with straps or bolts. This is where your wrench comes in handy.

Step 3: Disconnect the Old Battery

Time to free the old battery. Start by loosening the negative terminal first—it’s usually marked with a minus sign or black cable. Use your wrench to turn it anticlockwise until it’s loose. Then do the same for the positive terminal, marked with a plus sign or red cable. Order matters here to avoid short circuits.

Lift the cables off and tuck them aside. If they’re grimy, grab a Milwaukee Tools battery brush from AMP. A quick scrub keeps connections clean for the new battery.

Step 4: Remove the Old Battery

Forklift batteries are heavy—often over 100 kilograms—so don’t lift alone. Use a battery hoist or lifting tool to ease it out. Unbolt any straps or clamps holding it in place first. Then, gently hoist it up and out of the compartment. Set it down on a pallet or cart, keeping it upright to avoid spills.

Step 5: Install the New Battery

Now for the fresh power. Lower your new battery into the compartment, lining it up with the terminals facing the cables. AMP’s top-brand batteries, like those from Yuasa, fit snugly into most models. Secure it with the straps or bolts you removed earlier—tight, but not overtightened.

Double-check it’s stable. A wobbly battery can shift during use, and that’s a headache you don’t need.

Step 6: Connect the New Battery

Hook it up in reverse order—positive terminal first, then negative. Attach the red cable to the positive post and tighten it with your wrench. Follow with the black cable on the negative post. Snug connections mean reliable power, so give each a gentle tug to test.

If you spot corrosion on the cables, clean them with that Milwaukee Tools brush.

Step 7: Test Your Forklift

Close the compartment and fire up your forklift. Switch on the power and watch it hum to life. Take it for a slow spin—lift the forks, move forward, reverse. If it’s smooth, you’ve nailed it. Any hiccups? Recheck those connections.

Charging Tips for Your New Battery

A new battery thrives with proper care. Plug it into a charger from AMP’s lineup—like our top-tier optimisers—after the swap. Let it charge fully before heavy use. This sets it up for a long, reliable life. For wet British winters, a quality charger is a must, and we’ve got you covered.

Common Mistakes to Avoid

Even pros slip up sometimes. Here’s what to watch for:

• Skipping safety gear—acid burns aren’t worth the risk
• Mixing up terminals—positive first on, negative first off
• Rushing the lift—use a hoist, not your back
• Ignoring the manual—models vary, so check yours

Stick to these tips, and you’ll swap batteries like a seasoned mechanic.

When to Replace Your Forklift Battery

How do you know it’s time? Look for slow performance, weak lifts, or a charge that won’t hold. Most batteries last three to five years, depending on use. AMP’s range includes durable options built for the UK road—or warehouse floor. When it’s time, we’ve got the best waiting.
