True & false about VRLA batteries:

Answer

True

> A complete string of 2V battery can reach a high DC voltage level (e.g.: 400V DC), and tremendous amount of power also available inside the battery  need to be handle by qualified personal & respecting safety rules.


Answer

False

> Impedance measurement can hardly be used to predict battery end of life it can indicate string uniform degradation and loss of capacity.


Answer

False

> Equalization is not recommended for VRLA batteries, since it will participate to battery aging. It should be reserve to battery block replacement only.


Answer

False

> VRLA batteries life is affected by ambient temperature higher than 25oC.

> Battery room should be equipped with proper ventilation or air conditionning, to enjoy full design lifetime,.. and manufacturer waranty.


1.Even a 2V battery block might be dangerous if not handled with care. Ture or False
2.Although Measurement of Battery block impedance can help to predict end of life. Ture or False
3.Regular equalization charge can make VRLA battery last longer. Ture or False
4.VRLA battery can be installed anywhere. Ture or False
