NOTE
From the figure, MSE internal resistance can be read as
approximately 1 mΩ (at 100Ah), or approximately 0.13 mΩ
(at 1000 Ah).
When the battery deteriorates, internal resistance rises to 1.5
to 2 times the initial value (reference value).
With an MSE (seal type stationary lead-acid battery), battery
condition is regarded as marginal when internal resistance
reaches 1.5 times the initial value, and complete
deterioration is assumed when internal resistance reaches 2
times the initial value.
Even if different batteries have the same capacity, initial internal
resistance may vary according to battery type and maker. The
figure is only for reference.The internal resistance warning
(WARN) and fail (FAIL) values vary according to maker.
