Better to pay out almost maxed cards in full or twice over the next month?

Have one credit line of 325 almost maxed at 300 and one line at 300 almost maxed at 260. Minimum payment of 30 each but I always go past minimum. On the 300 line I once had to lock the card because a merchant was being irresponsible by sending random charges without telling. I eventually had that card reissued when they slept and tried to do it again with a 15 dollar charge. When all this happened I paid the bill half one week half the next out of confusion and that sent my score up past the original hit. Should I do this again for this card and pay the other in full or pay them both as halfsies? So confusing! I wish they would just up your score when you pay in full.
