Abstract
An improved battery refill system for filling and maintaining a number of interconnected battery cells at a predetermined level with liquid provided by an external liquid supply. The refill system includes a number of refill valves, each associated with a single battery cell, and a main supply valve which connects the battery cells to the liquid supply. Tubing is provided for connecting the battery cells in a chain or serial relationship. The tubing is fabricated from a plymeric material which, over an operating temperature range of between about -20.degree. F. and 200.degree. F., is substantially free of plasticizer bleed. The tubing is also sufficiently conformable and resilient over its service temperature range so as to remain in leak-tight engagement on both the barbed fittings and the compression fittings found in conventional battery watering systems.
