All cais up to and incl. model 1970 are Qqulppod W?:h.
44 Ah batteries. As from model 1971 L.H.D. cars are

thus ensuring good contact. When the battery is in place

The condition of the battery determines the ease of start-
ing, and regular testing and attention is therefore essen-
tial. Negligence in this respect may cause starting diffi-
culties, particularly in the winter, when starting loads are
higher and battery capacity lower because of the low
temperature. An insufficiently charged battery is liable to
freeze.

Evaporation and decomposition of electrolyte water My
muse the level to decrease gradually. Top up, using distil-
led water only, until the electrolyte level is appI’OX- 0-4 i“-
