In order to avoid the described problem, valve-regulated lead–acid batteries are often maintained at an excessively high float voltage, again with correspondingly adverse effects on grid corrosion, as already mentioned.
Nevertheless, positive grid corrosion is probably still the most frequent, general cause of lead–acid battery failure, especially in prominent applications, such as for instance in automotive (SLI) batteries and in stand-by batteries. Pictures, as shown in Fig. 1 taken during post-mortem inspection, are familiar to every battery technician.
