Battery testing research proves: Battery testing research proves: The internal resistance of a battery cell increases with age and discharge history. Batteries are often used as back-up systems in power supply and especially in UPS systems. In the event of a power failure, the functional readiness of such systems is therefore extremely important. Here it is particularly important that the battery can withstand the capacity required in each case. In addition, Legislation stipulates regular battery testing. And this applies to safety-related systems that are supported by battery-supported emergency power systems. These tests according to VDE must be recorded and thus verifiable at any time.
Regular battery tests are therefore mandatory. They serve to evaluate and analyze battery storage and battery capacity under load over a certain period of time. In accordance with DIN EN 60896-11, they are always carried out while the batteries are in their current operating state.
The battery testers from WGM Support partly measure the AC resistance and the DC terminal voltage of secondary batteries online. Our products thus provide reliable data on battery condition without reducing the remaining battery capacity during the measurement. The result: a flawless battery diagnosis. Furthermore, you can perform such a battery test on any battery system. With our battery tests according to current standards, you ensure the highest quality of your products.

This battery analyzer is widely used by service providers, operation and maintenance teams for battery management and measurement. The lifetime of a forklift battery in the form of a lead-acid battery depends on its care. However, this is only true under optimal conditions. Incorrect charging, overuse and lack of maintenance and care can strongly shorten the service life.
It is not important whether you check closed (VRLA) or vented (VLA) lead-acid batteries or NiCd cells. WGM Support has the right equipment for your battery maintenance. The products and related accessories provide useful battery health data without generating significant overheads or a possible reduction in remaining battery power. The Battery Analyzer BTA 100 is a portable test instrument. Battery Analyzers are the ideal test tool for maintaining.

Battery Ground Fault | GFL 1515
Quick localisation and elimination of battery earthing faults is enormously important. This is because poor insulation or earthing in the power grid can result in high costs. In some cases, this can even lead to power failures. The GFL1515 earth fault locator is an indispensable tool for identifying earth faults. Namely, those where electrical cables show a break.
According to DIN VDE 0100-410, the battery and DC power supply system should be checked for accidental earth faults every four months. The GFL1515 finds these virtual DC battery earthing faults. In both offline and online DC systems, the faults are quickly detected and localised. Overall, the output current of the unit is very low. But the output voltage can still be up to 1000V. Between 24V ~ 1000V, you can set it individually. GFL1515 identifies the unintentional earth fault by the faulty polarity. The earth fault locator can locate the battery earth fault without breaking the live circuit.
This means that the location of a battery earth fault is carried out during operation. A major advantage is the high level of interference immunity when the system is working online. As well as the multipath detection by current direction, phase angle and signal strength. Thanks to its patented technology, the Battery Ground Fault GFL1515 can locate leakage faults with an earth resistance of less than 1 MΩ. A precise current direction indicator for leakage current helps to quickly locate the faulty earth.
A built-in band-pass filter bypasses various interfering signals in the environment. All in all, the Battery Ground Fault GFL1515 saves hours of troubleshooting. And it helps to increase the reliability of your electrical installations. Earth fault DC – The device is used in locomotives, data centres, power supply companies as well as in telecommunications and many more.

Forklift Battery | BLE 600 | Stationary batteries
BLE 600 is a 3-in-1 device for charging, discharging and activating lead acid or NC batteries. The device is used for forklift batteries. Also for battery charging systems for UPS systems, emergency lighting systems and central battery systems. Due to its small size, the BLE 600 is a handy, portable device. It is applicable to single cells of 1,2V, 2V, 4V, 6V, 8V and 12V. Moreover, the compact device is perfect for regular maintenance of single cells. Especially of old cells.
Three functions of charging, discharging and activating can be used separately or together. This helps the user to maintain forklift batteries while facilitating the overall service. When the charge and discharge functions are used together, the affected forklift batteries are charged and discharged. And this is done in one or more circuits with low constant current. The BLE 600 can even charge or discharge the batteries several times individually.
Activation of the damaged material on the battery electrode plate corrects a caused malfunction of the forklift battery. That way, the battery is regenerated and the forklift battery capacity is increased. As a battery load simulator, the BLE 600 checks the discharge of the battery. In addition, it can use battery capacity tests to determine the actual capacity of battery systems.
Regenerating the forklift battery leads to increase the efficiencies of forklift batteries. Their resources are also effectively utilized. Long-term monitoring of the battery condition can even continuously check the traction battery. Thus, serious damage to the battery is prevented. The device can be operated via touchscreen and keyboard. On top of that, it has a direct USB drive for data transfer to the PC. Software updates can also be made quickly and easily. Users can also download the desired reports in Excel at any time.
