Alarm Battery 

Replacement battery.
Type: Lithium Ion
Application: 918S Alarm

When changing the battery, make sure to switch the unit off with the internal on/off switch. After changing the battery, make sure to switch the unit back on.

Under certain conditions the batteries that supply power to the audible alarm may loose charge more rapidly than what is normally expected. This potential charge-depleting condition occurs if and when a high liquid level is reached in the tank and maintained for an extended period of time. Even though the audible alarm is switched off, the batteries will continue to be drained of power if the liquid level remains above the high level point. If this practice is standard routine, it will lead to much shorter battery life and/or increased chance of overfill if the proper test procedures are not strictly followed before every transaction.

DISCLAIMER: Due to the class 9 hazardous material classification of lithium ion batteries, we will not ship batteries overnight air!  If you choose overnight air during checkout, we will contact you to arrange alternate shipping methods and payment.
