Forklift battery overhaul

Poorly maintained batteries decrease the life and performance of a battery, increase potential safety hazards and can damage a lift truck’s electronic components. Over-watering, under watering, overcharging, under-charging, accumulation of residue and corrosion of battery cables and terminals can greatly decrease the capacity of your batteries.

An under-performing battery isn't necessarily doomed to the recycle bin. MCP offers an overhaul program that will provide an evaluation of the current state, as well as the current capacity of each cell. If enough cells are indicating adequate capacity, we can replace the bad cells and overhaul the battery to it's previous glory.

On-site pickup

We will come on-site to pick-up the battery so you don't have to worry about freight.

Evaluation report

We will provide you with a capacity report indicating the power capabilities of each cell.

Loaner battery

MCP provides a loaner battery for the duration of the evaluation and overhaul processes.

What are the steps to an overhaul process?

Battery Cycling

Cycling the battery through charge and discharge cycles allows for the electrolyte to be mixed fully and also removes sulfate from the battery plates. The end result is an equalized charge that leaves the battery in a good state for a capacity test to determine the run-time of your battery.

Acid/Electrolyte adjustments

During operation, battery electrolyte levels can get out of balance through evaporation or over-filling of the battery cells. If the electrolyte is not at the optimal mixture, our service technicians will make an adjustment to bring each cell to the appropriate specific gravity. This adjustment allows for the battery to work at its peak efficiency.

Capacity test

A capacity test is performed by our technicians when a battery is placed under its rated load. Cell voltages are recorded hourly to plot the rate of discharge related to opposing cells. If one or a few cells degrade faster than the average, those cells may need to be replaced. The capacity test gives a written report detailing how the battery will perform under its rated load.

Reporting / Evaluation

After a capacity test, we will discuss the current capacity of your battery and provide a recommendation to continue with the overhaul, replace cells or recycle the battery.

Cell replacement

MCP keeps an inventory of standard sized cells and can make cell replacements quickly and effectively. If your battery is in need of cell replacement, it can be completed in our local shop in a timely manner.

Battery cleaning

Battery cleaning is provided to remove any residue from the top of the battery. This residue is conductive and can create a electrical path to the metal housing of your battery. This situation can cause your lift-truck controller to become damaged or receive false electrical signals resulting in unusual equipment behavior. Cleaning the battery will eliminate the chance of stray electric signals.


Painting the battery does more that provide a good appearance for your equipment. Removing rust accumulated on the battery case will reduce the chance of structural problems with your battery.
