Yes. As long as they are both the same format. The only difference is the capacity of the battery. The 2.5 Ah will last longer than the 2 Ah will on a charge. The charger will work for both.

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.

Battery flat.? Dirty or corroded battery/drill contacts.? Bad connection in the internal switch or wiring.? Motor brushes worn out.?

Measure from flat to flat for the size. Or just buy a very inexpensive alan wrench set.

They make all types of drill bits for concrete. Home Depot or Lowes usually carries them.

battery must be discharged. connect to charger and wait.

either battery is charged or battery is bad. All chargers act different so I can't tell you. Try measuring the battery voltage with a meter. I assume you do not have another battery to try. If the voltage is about 40V then the device might be bad. If it is much less (discharged) then the charger might be bad. But the battery may also be bad. A high internal resistance on the battery might cause the charger to think the battery is charged because it isn't drawing much current

I can't even find the drill. I would go to aliexpress.com and search for a drill and batteries the matched as I suspect it is made in China (most things are)..

The battery is shorted.

It must be a 12V Lead acid or gel battery. Therefore any 12V battery charger should work. It may be tricky to get it connected easily.

is it a morse taper? if so lower the spindle and pry through a slot to remove the spindle. then identify if the chuck is held on with a bolt, threded or pressed in. if its a pressed fit here are chuck removal tools that look like wedges that remove the chuck from the rest of the spindle

Try-with channellock pliers. They usually leave marks on the chuck, but they're also more common than strap wrenches

Put some penetrating oil on the chuck and let it soak overnight, they should come loose.

try using a wire to connect the battery to charger it might be a loose connection . If it does not work battery or battery charger might not be faulty

Request the wiring diagram from Delta.

Contact Guardian Power directly to inquire.

Sounds like a broken wire in the motor circuitry. I would take it apart and look for an obvious open in a wire. If nothing is seen then the most inexpensive fix would be to buy a new one.

discharge the battery ....
