forklift Battery diagnostic

Precision Power Source offers forklift dealers and users cleaning, analysis and diagnosis of their forklift batteries, in a 6 stage process using state of the art equipment in our establishment. 

Our 6 stages process consist of the following:

1. Visual inspection

The first step is trying to understand the batteries most obvious problems by a visual inspection, to name a few things that we go through:

  • Symptoms of acid loss

  • Automatic watering systems

  • Corrosion

  • IC connector problems (Inter-cell connectors)

  • Signs of explosions

  • Physical damage

2. Wash and neutralization

In the second step, we wash the battery with water and acid neutralization chemicals. This helps provide clean and safe working conditions and also takes away eventual ”creep currents”.

3. IC resistance monitoring

In the third step we find and fix the high resistance parts of the battery, apart from eventual cells, because high resistance causes a drop in voltage and excessive heat development.

Typical causes of high resistance are:

  • Loose screws or corroded IC connectors

  • Sulfated /corroded connections

  • Bad welds

  • Bad cables

4. Pre-load test charge

In the fourth step, we give the battery a full charge in order to insure the accuracy of the diagnosis load test.

5. Diagnosis load test

In the fifth step, we measure all the cells OCV och SPGR when the battery is fully charged and thereafter perform a full load test thereby measuring the battery’s Ah capacity and study the results and get back to you with a protocol and our recommendations.

6. Post load test charge

In the sixth and final step, no matter what is the results of the diagnosis load test is, the battery will be fully charged upon its completion.
