Re Tests of P&R RR11-2 Battery.
This battery was received charged & was subjected to bench tests with the following results.
On Low Rate Discharge through an invariable external resistance of 1.80w, 56.8 ampere hours were realised. After a full charge a High Rate Discharge was taken through an invariable external resistance of .100w & the
Initial amperes were = 97.5
Time to 90 amperes = 11.4 min
" " 80 " = 16.0 "
The above results are not very good but it is hoped that it will improve in the course of its life.
Signed G.J.
This Sheet must be filed on completion of the work.
