Hi,
i have a triton 12v impact driver with a battery pack of 3 Samsung INR18650-15L in them. I have 2 batteries for it, they usually do 1 week for me with light/moderate usage. One of them now only do 1-2days and i want to replace the 3 batteries in the pack, but reading here i realized they might be 'reviveable' or maybe only 1 battery is actually bad from the 3. How could i test which one is good or bad, with no special charger etc.? i have a multimeter and automotive battery tester.

My second question is that if i could replace them with bigger capacity 18650s or can i mix them, are they fully compatible etc.?
Thanks
