I really didn’t want to wait several days for new chips if that was the problem. So, I took my handy dandy volt meter and measured the voltage across the reset pins of several new unfilled cartridges. They all varied, but one was up to 1.5V, so I figured that the reset voltage across the pins is supposed to be the battery voltage. The voltage across the VLM cartridge after changing the battery was 0.3 V, yet the battery was 1.5V. I took the battery out and used a little electrical contact cleaner on the battery terminals inside the battery enclosure, rubbed the contacts gently with a narrow flexible plastic tip, reinstalled the battery, and voila, 1.5V across the reset terminals. I installed the cartridge, and it now is recognized.
These battery chips would be fantastic if they made the batteries easier to remove and install. In fact, I would suggest that they be supplied with the batteries NOT installed to help prevent corrosion.
I would recommend to anyone to measure the voltage across the reset terminals. If it is less than 1.5, remove the battery and measure the battery voltage. If the battery voltage is low also, replace the battery. However, I’d also highly recommend spraying a little electrical contact cleaner into the battery holder.
