| A few years ago, Gold Seal Electrolyte was evolved by Mr. Brust, a chemical engineer of German origin, and finally improved in association with Mr. A.{Mr Adams} Fuchs. It differs from all other Electrolytes and has been subjected to the most severe tests under every conceivable working condition, on cars, boats, electrically driven vehicles, etc., until it has reached its present perfected condition. These trials have extended over a period of five years, involving a large expenditure. THE ADVANTAGES OF GOLD SEAL ELECTROLYTE. (1) Any new uncharged lead accumulator can have its first or forming charge given it at four times the normal rate, without injury; this is due to the practicability of charging at 35 to 40 amps. as against 10 to 20 amps. in batteries filled with any other type of electrolyte. (2) When charging an accumulator filled with Gold Seal at four times the normal rate (as in (1) above) the temperature rise is at least 40% less than that given by other electrolytes at the normal charging rate. (3) An accumulator in use, when run down, can satisfactorily be charged in one hour, the normal time with ordinary electrolyte being 10 hours, and will then show a similar capacity. (4) The current consumed when recharging for the same capacity is less than 20% of that used in recharging accumulators fitted with other electrolytes, owing to diminished heat-generation. (5) In an emergency any motor vehicle, started by a battery, that is disabled owing to the starting battery being run down, can be restarted within five or ten minutes by refilling the accumulators with Gold Seal Electrolyte, no charging being necessary; the battery will give sufficient power for restarting and will be recharged in the usual way while the vehicle is running. If current is available for charging, the time for charging is approximately one-tenth of that needed for other electrolytes. | ||
