Recently, I kept finding battery leaks:


Same pattern, leaked batteries are not discharged. They can still power a flashlight.
I suddenly realized that all those are DURACELL from Costco. I used to use no-name batteries, rarely had any leaks. This reminds me that last year I had to throw out some unused DURACELL because they leaked in storage. It seems that DURACELL is designed to leak, regardless of usage!
- Snap-On 1/4" Techangle. 3 AAA batteries were in the battery holder, not in the torque wrench. 2 out of 3 leaked. Voltages were still more than 1.5v
- Bosch Laser distance measure. 2 out of 4 AAA leaked. Voltages were all above 1.5v.
- Coast Headlamp. 2 AA leaked. Rotted the circuit board.
- Nikon camera flash. 4 AA batteries made a mess.
- Gardner Bender voltage meter (cheap meter from Menards), just found out this morning:
