Martha, SK and Hariprakash, B and Gaffoor, SA and Shukla, AK (2003) Performance characteristics of a gelled-electrolyte valve-regulated lead-acid battery. In: Bulletin of Materials Science, 26 (5). pp. 465-469.
12 V/25 AH gelled-electrolyte valve-regulated lead-acid batteries have been assembled in-house and their performance studied in relation to the absorptive glass-microfibre valve-regulated and flooded-electrolyte counterparts at various discharge rates and temperatures between $-40^oC$ and $40^oC$. Although the performance of the gelled-electrolyte valve-regulated battery is similar to both the absorptive glass-microfibre valve-regulated and flooded-electrolyte lead-acid batteries at temperatures above $0^oC$, it is superior to both the flooded-electrolyte and absorptive glass-microfibre valve-regulated lead-acid batteries at temperatures between $0^oC$ and $-40^oC$. The latter characteristic is attractive for expanding the application regime of valve-regulated lead-acid batteries. The corrosion rate for the positive grids in the gelled-electrolyte is also lower than both the flooded-electrolyte and absorptive glass-microfibre configurations.
