2 x Replacement Batteries for Eve K-305177 Visonic Siren Batteries

This pair of batteries are perfect replacements for Eve K-305177 Visionic MCS-740 SR-740 PG2 wireless outdoor siren or bell box batteries. These lithium 3.6V 3.5Ah are fitted in pairs. Every few years these non-rechargeable batteries simply come to the end of their natural life and therefore need replacing. The 3.6V Lithium K-305177 alarm battery packs come with the four wires and the correct connector plug to it first time every time.
