Hi Guys, i found a couple of caps in the scrap yard,these were from a speaker freq. crossover, they are electrolitics but have no polarity,the ends are just like a resistor,they marked like this, 8.5MFd,100v,85%,NP, 8850,my question, can this be used in any polarity?

NP sands for not polarised so they can be used as electrolytics without polarity issues

Thanks alot
