Aren't the battery costs of AGVs a significant barrier to reducing equipment maintenance costs?

Alkaline batteries for AGVs are very expensive. Due to the high replacement costs, some companies are considering discontinuing AGVs. What we propose this time is the activation of alkaline batteries. NiCd and NiMH batteries inevitably experience a decrease in capacity due to the effects of memory. Depending on the usage environment, cell degradation occurs in about four years. The activation treatment achieves capacity recovery, increased charge and discharge capability, and voltage stabilization. It also has cost-saving effects and is very economical.
