What type of electrolyte is used for Ni Cad batteries?

for Ni Cad batteries. Type ‘B’ Electrolyte is a solution of lithium hydroxide crystals and potassium hydroxide flakes in DM/DI water. The number following the ‘B’ represents the quantity of lithium hydroxide in grams (assuming 100% assay) per liter of electrolyte.

Which electrolyte should I use for my Ni-Cd battery?

Use only electrolyte approved by HBL Power Systems Limited, for our Ni-Cd batteries. The alkaline electrolyte (solution of potassium hydroxide in DM/DI water) is a strong caustic agent. Wear rubber gloves, eye protection and long sleeved clothing when working on the battery.

What are the ventilation requirements for battery rooms?

The ventilation requirements for battery rooms, cabinets or compartments are based on the required reduction of the concentration of hydrogen generated during charging and safety factors which include battery ageing and the potential for fault (“worst case”).

How do you charge a FNC battery?

Discharge the batteries by using a charging/discharging device with nominal current I until the battery voltage has dropped to 1.0 V per cell. Seal each grid|power FNC®-cells with a yellow transport plug. Filled and charged (FC) grid|power FNC®-cells prepared in this manner can be stored up to three years.

What is a good insulation resistance for a battery?

When commissioning a new battery, the insulation resistance must be > 1 MΩ. This value falls with the operating time (caused by aerosols from the batteries, condensation and dust) and, in accordance with IEC 62485-2, it should not fall below the value of 100 Ω per volt of nominal voltage.

Where should a battery rack be located?

HBL recommendation: 1meter in front of and between the battery racks for parallel Rows arrangement, Otherwise, in accordance with local regulations. It is impossible to stop gases from being generated while over charging batteries; therefore, the hydrogen concentration in the air must be reduced with sufficient ventilation.
