So, what’s the best battery out there? It really depends . . .

Below is a summary of the strength and limitations of today’s popular battery systems. Although energy density is paramount, other important attributes to batteries include service life, load characteristics, maintenance requirements, self-discharge costs and, of course, safety. Nickel-cadmium – mature … Continue reading

Exercise is important for your batteries

It’s possible to prevent damaging memory from developing in your batteries. Crystalline formation, which causes battery memory in nickel-based batteries, is most pronounced if the battery is left in the charger for days, or if repeatedly recharged without a periodic … Continue reading

Does your battery have memory?

The term “memory” was originally derived from “cyclic memory”; meaning that a nickel-cadmium battery could remember how much energy was drawn on preceding discharges. On a longer than scheduled discharge, the voltage would rapidly drop and the battery would lose … Continue reading
