Rechargeable Batteries: Pros and Cons for Remotes
Although rechargeable batteries such as nickel-metal hydride (NiMH) cells offer the significant advantage of being reusable up to approximately 1000 cycles, their nominal voltage of 1.2 volts is clearly lower than the 1.5 volts typically supplied by standard alkaline batteries, which can influence the performance and responsiveness of low-power devices like remote controls. Among the pros and cons of rechargeable batteries, a high self-discharge rate, typically 10-20% within 24 hours, leads to frequent recharging, especially in devices used intermittently. In contrast, alkaline batteries provide a longer shelf life, often up to 10 years, making them more suitable for rarely used remotes. While NiMH batteries may offer long-term savings through reuse, their suitability depends on device voltage requirements and user charging habits. Choosing batteries with a low self-discharge rate can help improve retention and reduce the frequency of recharging in low-use devices.
