Disclosed herein is an automatic fluid filling device for maintaining fluid at a desired level in one or more battery cells each having a cell opening. The device comprises a plurality of members each removably insertable into a battery cell, and each including wall means having a first portion sealingly engaging a battery cell opening and also having a second portion located above the first portion, which second portion partially defines a generally air-tight chamber located above the battery cell opening, which second portion also includes an aperture and a removable cap which sealingly engages the aperture for allowing access to the fluid in the battery cell. The wall means further includes a third portion which partially defines a passage located below and in communication with the chamber and in communication with the battery cell for affording fluid flow from the passage to the battery cell. Each member also includes a fluid level control tube having an upper opening extending into and being in communication with the chamber and having a lower opening extending into the battery cell to the general level at which the fluid is desired to be maintained in the battery cell. Conduit means can be provided for connecting together the member passages in series, along with a reservoir connected to an end one of the series of connected passages for affording fluid flow through the passages and into the battery cells.
