✦ Synopsis

A detailed evaluation is made of the performance of a wide range of lead/acid battery technologies operating under both simulated and field conditions encountered m remotearea power-supply (RAPS) duty Laboratory studies indicate that the most promising designs of battery are (i) flat-plate, flooded-electrolyte, with thick plates and low-antimony positive gnds, (a) tubular-plate, flooded-electrolyte, with granular oxide (m) flat-/tubularplate, gelled-electrolyte For the first two technologies, this prediction has been realized by the placement and successful operation of batteries in RAPS field sites Battery failure is associated mainly with degradation of the positive plate, namely, breakdown/sheddmg of active material, together with the development of inter-plate short circuits, corrosion/ growth of grids, irreversible sulphation (including penetration of separators) Information acquired from the research programme is being used to design advanced RAPS batteries The latter are currently under assessment, both in the laboratory and in RAPS installations 'Paper presented at the Workshop on the Development and
