[2] The delay in construction was caused by a disagreement at the War Office between the Inspector-General of Fortifications and the Director of Artillery over the installation of disappearing mounts.

A report in 1906 by the Royal Engineers stated: ... this important new work is now nearing completion it only requires a set of 1.8-inch accumulator pipes for A/2.

Its command post was in the same building as the Port War Signal Station, which was located between the battery and Bembridge Fort to the north.

[2] During the First World War, the battery's main role was to defend the Isle of Wight's torpedo boats' anchorage against long-range fire from armoured cruisers.

[2] Under war-time conditions, the battery had toilets, wash block, mess, and general storerooms as well as a workshop and telephone room.

Between 1922 and 1924 the battery's barbettes were replaced with new mountings that allowed the guns to elevate up to 30 degrees, increasing the effective range beyond 6,000 yd (5,500 m).

In 1927, Culver was used as the test centre for the Fortress Plotting system, a type of experimental corrected firing for coastal artillery.

The battery's two main guns now had ranges of up to 17,000 yd (16,000 m), meaning they could assist Nodes Point to prevent long-range bombardments of Spithead or Portsmouth Dockyard.

In 1943, a Coastal Defence(CD)/Chain Home Low(CHL) radar station was erected just to the east of Culver Battery.
