Batteries, Battery Test Equipment, Load Banks, Stationary/Reserve PowerSBS-2206S: Battery Capacity Tester – Battery Testing Solutions – Exponential Power
The only way to know if your stationary batteries will perform to specification is to test them regularly.
NERC standard PRC-005-2 requires that vented lead acid and nickel cadmium (NiCd) systems be discharge tested every six years and valve regulated lead acid (VRLA) batteries every three years. IEEE recommends load testing stationary flooded/vented lead acid and NiCd stationary batteries every five years and VRLA batteries every 12–18 months.
The SBS-2206S constant current load banks are an easy and affordable way to perform accurate IEEE450 (Vented Lead-Acid), IEEE1106 (NiCd) and IEEE1188 (VRLA) load tests.
These units are quick and easy to set up. They display the voltage, current and Ah removed from the string during the test. Since this is a constant current load bank, the user also does not have to adjust the current during the test.
These load banks come standard with multiple adjustable stop points and built-in protection to ensure that the batteries are never damaged due to over-discharge.

Batteries, Batteries, Industrial/Utility, Nickel Cadmium/Ni-Cad, Stationary/Reserve PowerSaft Uptimax Maintenance-Free Ni-Cd Batteries – Stationary and Reserve Power Batteries – Exponential Power
The latest generation of Uptimax nickel battery technology is the perfect fit to replace lead-acid batteries thanks to its 1.39 V/cell single level charge. When a fast recharge is needed, 95% State-Of-Charge (SOC) in 8h can be reached at 1.45 V/cell for minimal downtime and optimal availability. These improvements come in addition to the key existing benefits of the Uptimax Ni-Cd battery range.
Uptimax Ni-Cd battery combines maintenance-free* operation with total reliability for industrial backup power applications, high electrical performance, long operational life of over 20 years and a low TCO (total cost of ownership).
Uptimax pocket plate nickel battery is designed to form the heart of Uninterruptible Power Supply and backup power systems that operate in the event of a loss of the main power supply to facilitate the safe shutdown of processes, safeguard computer data and provide bridge to standby power. Typical power backup applications include UPS, substation switchgears, process control systems, emergency lighting, fire alarms and security systems.
