Figure 8.9 shows an improvement in relative position of the denser, heavier battery systems when
compared on a volumetric basis.
(Note: As stated earlier, these data are necessarily generalized and present each battery system
under favorable discharge conditions. With the variability in performance due to manufacturer,
design, size, discharge conditions, end voltage, and other factors, they may not apply under specific
conditions of use. For these details, refer to the appropriate chapter for each battery system.)
