Abstract :
The operation of a 24 V VRLA battery formed by two strings of dissimilar cells and monoblocs in a 100% depth of discharge C3 discharge/charge cycle service has revealed not unexpectedly that an asymmetric current flow from the strings occurs but that its implication on ultimate cycle service life is less significant than the strict rule of “do-not parallel dissimilar strings” would indicate
