Dont know when the last time the battery on my apex was charged, so was thinking of giving it a slow charge on the trickle charger, do these sled charge the battery while they run or...., also how do I go abouts charging it, shouldve done it when it took it out and changed the oil filter but didnt, there are these to mysterious wires under the hood which seem to connect to the battery, they are kinda thick and theyre ends are taped off?, is this maybee where I can charge it, and is it safe to do so? Let m know....
