You are facing a puzzle many owners of cordless tools face - often!

It could be either - unless you have a friend or neighbour or a nearby supplier that has the same model charger or battery to allow some swapping around.

The charger I have seen looks like an old ni-cad type charger rather than a modern lithium type. Ni-cad batteries self discharge and if allowed to become discharged through lack of use they soon become useless if not quickly recharged.
Generally ni-cad batteries should be checked and recharged if necessary each month. Young batteries shouldn't need charging much during storage but the older they become the more they will self discharge until they are useless.

Only you know the history of the battery you want to recharge. The one hour fast charger has a certain amount of intelligence and safety built in and if working correctly will reject batteries it thinks will be unsafe to charge.
If the battery will dismantle easily you could check each of the six cells with a voltmeter. If one or two are completely dead while the others have voltage it suggests the battery is past it...

Beware there Is no fuse inside for repairing used only for fire safety used, on marketing technical base there are no wiring diagrams beware of ordering a separate print of the charger can often be more expensive than a whole new charger and also look first for the option on warranty. powercord problems can a problem but the li-ion chargers are build up mostly with smd components and if damaged there is no support to repair for novice to refurbish.

Probably not - I have tried and the industry considers even expensive chargers to be throw away items along with cordless tool batteries.

There are plenty of generic circuits available for chargers of all types of battery but none for commercial models.

Good cordless tool battery chargers tend to have a good deal of logic circuitry to provide them with an intelligent testing capability and prevent the "attempted" charging of faulty batteries. This makes fault diagnosis difficult and puts the process beyond the scope of the home repairer.

Reversible drills sort of threw a spanner in the works of established practices of providing a right-hand threaded spindle onto which a chuck was simply spun into place and the final tightening would take place in use.
Adopting the Jacob's Taper would have provided the answer but in production cost always has the final word. In desperation some of those early reversing manufacturers opted for adhesive, making replacement practically impossible.

Computer aided manufacture hit the industry like a storm and provided the answer by making it economic to provide a left hand threaded counterbore in the conventional threaded spindle allowing standard (or slightly modified) chucks to be retained by a 5mm LH countersunk screw when reversing.
The system works well for drill/drivers but the counter screw often becomes damaged and impossible to remove with combi drills used extensively for hammer drilling.

Removing a standard keyed chuck has always been fairly simple but keyless chucks, especially low cost keyless chucks fitted to cordless drills can be a huge problem. Corded drills usually have enough torque to be driven in reverse with the chuck held tightly in a vice.
Over the years I have failed to remove one chuck, destroyed a couple of chucks in order to remove them and even had to dismantle a couple of drills so the shaft could be gripped in vice jaws...

Fixya is not a source of Makita parts.

Some generic label engineered cordless drills used generic batteries - these are mostly the types supplied with a slow charger rather than the 1 hour fast charger though some of the larger tool distributors have managed to source some fairly respectable cordless tools at keen prices, the supplier provides them mostly as throw away tools.

The trouble is, few suppliers of those lower price point tools provide spare batteries. If a replacement battery can't be obtained as a spare part from the supplier, for practical purposes it leaves 3 choices...
Scrap the drill and start again.
Recondition the battery yourself.
Have the battery reconditioned by a specialist.
