Up AGAIN goes the LIFE of EXIDE Ironclad batteries HE average life of Exide- Ironclad industrial truck bat- teries renewed during the year 1929, again showed an increase over the highest previous year’s record. Constant improvements in de- sign and construction have re- sulted in an increase in the service life delivered by Exide- Ironclad Batteries for six consec- utive years, and a total increase of 42.4% over the period. (Based on actual service records of bat- teries renewed.) This means more battery for the money, and lower battery costs, as this increased life and greater durability have been ob- tained at no increase in prices. Such improvement in any prod- uct merits consideration. When you next need a battery, buy an Exide-Ironclad.
