From the Rolls-Royce experimental archive: a quarter of a million communications from Rolls-Royce, 1906 to 1960's. Documents from the Sir Henry Royce Memorial Foundation (SHRMF).
Continued report on cell testing, comparing the weight and performance of Edison and Exide cells.

-3- Contd.

The lugs require a quicker taper as they get
frosted on end and cause a great strain on the plate joint which
seems rather weak.

Komparison as regards weight -
Edisons total weight } 32 1/2 [strikethrough] 34 lbs. for 8.5 volts.
including tray }
Exide cells.
including box. 15 lbs./4 volts.

(see later weight comparisons).

These do not compare as they state for lightness.
These cells I am putting into daily use for coil
testing and will report again later.
