The TDS 3 salinity meter is excellent for measuring water. It shows how much salt is in the water. The primary batteries typically last a long time—they can last for about a year. However, after that, the batteries may run out and need to be replaced. So, which batteries are best for the TDS 3?
Batteries for the TDS 3 salinity meter
The device uses two 1.5-volt batteries. Together, they produce a voltage of 3 volts. They are flat, miniature cylinders. One side has a significantly larger positive pole. The other has a slightly indented negative pole. The positive side contains markings, such as the manufacturer, the electrolyte used, and the voltage level.
For the TDS 3 salinity meter, 357 A batteries and similar ones are ideally suited LR44and A76. Just be sure to buy batteries that were manufactured very recently. For example, 1-2 years have passed since their manufacture. Keep in mind that the longer batteries sit in a store or warehouse, the less charge they have.
In reality, 1-5% of their charge can be lost per year. If they are stored for more than 5 years after production, their charge may no longer be 1.5 volts, but 1.4 volts. Therefore, the manufacturing date is a very important parameter.
