Ripple and sealed Lead acid batteries

Postby **ChrisB** » Sat Jul 18, 2009 12:14 pm

I'm aware that sealed LA batts dont like being subjected to a high DC ripple, can I get away with just stuffing a nice large electrolytic cap on the output to smooth it out ??

Thats what the capacitors inside your controller are for. If you put extra capacitors in yourself between the contactor and the controller you will need some kind of precharge circuit otherwise your contactor will be at risk of premature wear due to arcing of the contacts.

Sorry I didnt really make it clear what I was doing :oops:

Basically I'm trying to clean up the output of a normal LA regulated bench charger so that I can use it on SLA's, currently the output I feel is somewhat rippley. not that this bothers LA's but I had in the back of my mind that a high ripple current upset SLA's.

Does that make sence ?
