I have a skil cordless drill and just recently the battery charger took a dive.Is there any way I could hook up any kind of charger to charge the batterys?I used a trickle charger and it worked for a little while but it seems to have gone by the wayside.The drill was acheap one but it still works great.I just want to know if there is any other alternative to charging the battery or do I scrap the whole thing?The Skil Warrior drill is obsolete therefore impossible to find parts.
