What is the battery life of the
water leak detectors?

The battery life of the WL4200, WL4200S and WL4200C water leak detectors depends on the system to which they are connected and the type of batteries used.

The Sinopé water leak detector comes with 2 AAA lithium batteries that can last for up to 10 years in regular use when paired with the VA4220WF valve.

*Note that lithium batteries are preferred because they not only have a longer life, but also because they are not likely to leak like alkaline batteries, which can ultimately damage the device.
