Stationary Vented Nicad batteries
- Thread starter SAkieran
- Start date
'Vented' NiCad batteries immediately suggests high capacity 'wet' cell types. Smaller NiCad batteries are unvented, except for the safety valve. Like lead-acid wet cells, banks of NiCad are topped up with distilled water, but are alkaline as the electrolyte is a dilute potassium hydroxide solution. Maintenence equipment should therfore be kept separate from that used for any lead-acid batteries that may be installed at the same location.

Alcad produce a range called Vantage and Vantex. These are recombination Nicad cells that they claim do not require topping up during their 20 year life if charged at the correct voltage and temperature.

SAFT make the Uptimax and Hoppecke the FNC-VR which use similar recombination technology to achieve similar topping up intervals. Apologies to Alcad, I was trying to think of their name yesterday!
