Embodiment Construction

[0091] The following examples relate to five sets of individual batteries having the properties described in Table 1 below. All tested batteries are automotive batteries with a capacity of 75Ah at 20°C, a charging voltage of 14.4V, and a test temperature of 60°C. Battery tested for 84 days.

[0092]

[0093] Table 1. Test batteries.

[0094] exist Figure 1-3D Middle: battery A is represented by a thick solid line; battery B is represented by a dashed line with circular data points; battery C is represented by a solid line with circular data points; battery D is represented by a dashed line with triangular data points; battery E is represented by a solid line with triangular data points.

[0095] now refer to figure 1 . exist figure 1 , the cumulative moisture loss data (in grams) over the duration of the 84-day test is presented graphically. Data were collected at 21-day intervals (Test 21, Test 42, Test 63, Test 84). As can be seen, Cell C exhibited the least am...
