Lead-acid cells (10 Ah) were assembled with three-layered separators
comprising untreated AGM, MMAGM, MPVP or MPVS
membranes and set to cycling tests at 5 hdischarge rate (I = 2A) until
an end-of-discharge voltage U= 1.70V and charge as per the regime
described in Section 2.3 above. The end-of-life criterion was when the cell capacity decreased below 7 Ah. Fig. 5 presents the capacity
versus cycle number dependences for the four types of cells with
different membranes
