![]() Current flow with the pickup unplugged should be zero. A way to check that is to snap only the negative terminal of the battery into the snap connector, and then connect an ammeter between the positive terminal on the battery and the positive terminal on the snap connector. ![]() If the battery is still lasting 3-4 months, that would mean a really minor short, if that were the case. (And check the date on the packaging.)Īnother possibility is that something has caused your input jack to stop completely opening the circuit when the plug is pulled out. They have excellent longevity, and they don't vomit up their guts and ruin your equipment when they fail. My best luck lately in pickups, test instruments, etc. There are people selling "old" batteries (that is, approaching their expiration date) as new. In the past couple of years, I've noticed a lot of variability in quality and life of batteries. Going to a luthier is kind of a big deal here. What could be the problem? Is there any way I could check for it myself? Therefore, I doubt the cable is to blame. The cables are different (length and materials), from different manufacturers. The previous one was also new, from about 6 months ago. My current cable is new - about 3 months old. The battery I used before this one was a Grundig battery, which also did not last for very long. I doubt somewhat that the battery manufacturer is to blame. I have changed to this battery only 3 months ago. I measured it today at home - only 1V left!! ![]() Yesterday at a performance, my signal was extremely low. Only 2-3 times a month, on performances.įor some reason, the pickup battery now runs out already after 3-4 months. I was playing it amplified very often then, through all rehearsals, at least 5 hours a week. When I just received it, 4 years ago, the pickup battery lasted for over a year.
