WILPA2549A Water Meter battery replacement.
High quality compatible replacement battery for WILPA2549A, 3.6v 17ah lithium thionyl chloride battery for water meter reading modules.
Water meters with remote reading capability rely on a small, long-life lithium cell to keep transmitting data for years without a service visit. This WILPA2549A compatible replacement matches the original 3.6V 17Ah lithium thionyl chloride (Li-SOCl2) specification, so it drops straight into the meter's reader module in place of the depleted factory pack.

Unlike a rechargeable pack, this is a primary cell, so there's no charging involved and nothing to top off. Li-SOCl2 chemistry is chosen for exactly this kind of job because of how slowly it self-discharges, losing under 1% of its capacity a year. Manufacturers typically rate service life on the WILPA2549A battery at 6 to 15 years depending on how often the module transmits.
When this cell eventually reaches the end of its working life, it shouldn't go in with household rubbish. Lithium cells contain reactive material that needs proper handling, and most councils and battery retailers run take-back schemes for exactly this kind of small sealed lithium pack, recovering the lithium and other metals for reuse. Fitting a fresh compatible replacement is the easy part; just make sure the old one goes to a battery recycling point rather than the bin.
