Cross-posting from the two-pack SKU... with an update as of 12/12/12.

My two battery packs, although 3 years old, have probably been charged less than 75 times and that's probably an overestimation. I'm just a homeowner and they sit in the basement, sometimes on the charger, sometimes not.

They have just both failed in the span of a month and the charger refuses to try to charge them.

Makita Service center says that there is no systemic issue with the battery pack design and all of us complainers have either abused them or simply worn them out.

I just purchased two more packs before I read of these issues, but will never purchase again.

UPDATE 12/3/12
I put both old battery packs on a laboratory power supply set to constant current with a maximum voltage of 17.5v. I started charging the battery packs at ~50ma and gradually turned it up to 400ma. A couple hours later the power supply stopped pumping current when the battery pack voltage reached 17.5v.
Removed the batteries from the power supply and let them sit for a bit - open circuit voltage stayed above 17v.
Tried the battery packs on the Makita charger again - Still locked out as before, refuses to recognize as a good battery pack.
Used the battery packs all afternoon in the basement - there is nothing wrong with the cells. This is a Makita design issue as other users have pointed out.

UPDATE 12/12/12
Continuing to use the "bad" battery packs after manually charging them via a laboratory power supply. They work (almost)as new. They still will not charge in the Makita charger - registers as a bad cell. Open circuit voltage is still 17.x volts, obviously not a bad cell, but bad design flaw in the electronics.

I have owned a set of Makita tools with the LXT batteries for a couple years now and I have noticed absolutely zero power loss or any other problems. I use them quite regularly whether building concrete forms, decks, remodels, etc. I can think of three things that may be happening to the batteries of those who have commented on bad performance or longevity; (1) Occasionally, batteries can be bad from the factory (I have yet to own a milwaukee tool with the new "V" or "M" series battery that holds up past a few months. I have both V28 and M12, and have had ALL packs replaced) (2) It is possible to have a bad charger which is damaging the batteries itself, or (3) Perhaps the users are taking them all the way to the point of stalling and complete discharge, and for that the batteries are truly not made to do. It is best that once you notice the battery pack is wearing down, to grab a fresh one and put the discharged on the charger to cool down and refresh. Also, if the batteries are being stored for most of their life, it is best to keep the charger plugged in and rotate batteries through it to keep everything active and refreshed. Lithium batteries have computer chips and sophisticated circuitry, allowing them to constantly be charged without damage. Ni-Cad on the other hand are not supposed to be charged over and over again because they typically have memory effects and lifetime charging limits. It is best to mostly, not completely, discharge a Ni-Cad before replacing back onto the charger. Because a consumer only has ultimate control of this last variable, it is a good idea to read the owners manual and find out what the manufacturer thinks is best operating practices.Read more ›

These batteries have a design defect that will kill them prematurely and a 'feature' that will force you to buy another.
There is internal circuit to control charge and count how many times it has charged or failed charging. This circuit is powered off a couple cells only, so if you leave without use too long those cells will zero out while the remaining are fully charged. This will cause a fail charging, and while it could be recoverable (if not too deep discharged) the scheme of a 'smart battery' (should we call it a scam?) prevents it from charging on the 'smart charger' and you are out $100 for a new one.

It is another 'evil marketing' ploy where someone at Makita (formerly known for excellent products) convinced that they could make a lot more money selling a battery a year than one tool every ten.

After buying and disassembling a new battery (11/2011 vintage) it proves they were indeed in bad faith. he battery circuit is now redesigned, gets wired to all steps in the cell (perhaps just to alternate which one to draw power from, perhaps to further reject batteries - to be seen). Another suspicious move is that they added a white plastick 'seal' covering one of the screws (easily replaced with a white gift card portion punched on a paper puncher). Mechanical changes were also made inside the battery pack so the new cells and circuit will not fit inside the old one without cutting some plastic portions.

Yet to be seen is if the new model will also die prematurely or if they fired Dr. Evil Sales and good engineering triumphed. Stay tuned...
