Re Tests on SU Battery (176) This battery was given a low rate discharge through a constant external resistance of 1.80w & only gave 37.8 ampere hours. The Oldham cells shewed positive weakness. After a full charge the battery was given a high rate discharge through a constant external resistance of .100w. Initial amperes = 100 Time to 90 " = 5.1 min " " 80 " = 7.0 " Both of these results are very poor & are due to the Oldham cells having such a poor capacity.
