    Good point. I never experienced this issue and always thought its a myth that we shouldn’t combine them. So I learned something. But I don’t use non-rechargeable batteries anymore anyway.

      It took me decades to finally figure this out. It wasn’t until I started building solar systems and batteries that I realized what was happening.

      You can have the same issue with rechargeables, but they are more resilient. Running them in parallel will work fine because the batteries balance out their state of charge. When you run them in series they have no way to balance out and one is always dragging the rest down. If the difference is too much then that lowest battery heats up considerably. That cooks the electrolyte.

        Interesting, even with rechargeables. Good thing since the 90s Game Boy I only use same set of rechargeable batteries from same manufacturer only, and always put them out when not in use. That’s probably I never had an issue anymore. The humidity of the environment and quality control of the batteries are probably an important factor too. I can imagine this happens more often in some regions of the world than others in example.
