measuring ripple factor in battery chargers

[proelect8717]

Hi all,

We have a 184 Cell (each cell is of 275Ah, 1.2V, Gaz Make NiCd )battery bank and a battery charger which is some 20 years old. Now, I want to test battery charger for its performance that it is performing good or not?

1. What paramters should I test and check for performance of battery charger?
2. Should I measure ripple factor to get idea about health of filter capacitors?
3. How should I measure ripple factor? with what equipements?

Thanks for your consideration.

What's the rating of the current (old) battery charger?

there are lots of parameters to look for. firs of all have a look on the preciseness of the charging voltage. In different temperatures. then have a look on the current ripple, especially on the end stage of charging. Life, Efficiency and etc would also have greate value to be considered.
