    18v Makita LXT BL1830. Problem is now that charger will not charge two of the three batteries in the kit, saying "they're broke" and yet the actual battery was still holding charge and would power the impact driver no probs. Even when completely flat, the charger will not accept these batteries. Are the batteries at fault or is the charger dodgy?

    Similar problem - 18v Makita Lithium Ion drill, about 2 years old, 1 of the original batteries stills accepts a charge. Have gotten 4 replacements that will work for 2-5 charges and then show up as bad on the charger and it won't charge them. Home depot has exchanged them as long as the date code stamped in the top is less than a year old. Opened one up and saw a circuit board on top of the battery pack - who needs that level of complexity just to charge a battery...just more to go wrong.

    Have tried it hot or cold, batteries completely flat or still with enough charge left in them to run the drill. Same story, the charger says they're no good and refuses to charge them.

    Can you bypass the "smarts" and just apply 18v for 15 minutes? At what current rate (amps)? which terminals?

Make sure the charger is cold or keep it in a cold place, when makitas charges get hot, they will not charge.

Need cap off makita 9000 battery pack to replace bad cells

Yes, I agree with Wylie Johnson. You should replace a new 9000 battery for youe drill. I found the capacity of your orignal battery is only 1.3Ah. You can get a 3Ah makita 9000 battery. It can last longer in your work.
