Consumers can be confused as to which battery to buy for these devices. This handbook will provide a better understanding of rechargeable Nickel Metal Hydride (NiMH) batteries, their use, and advantages for the consumer. | |\n|  | Many battery applications are well suited to be powered by NiMH rechargeable batteries. In general, devices that require large amounts of energy and are used frequently are well matched to the performance characteristics of NiMH batteries. Examples of these devices would include digital cameras, GPS units, and MP3 players.\u003Cbr>Early AA NiCd rechargeable batteries provided approximately 25% of the capacity of alkaline non-rechargeable batteries. However, the latest AA NiMH batteries provide approximately 75% of the capacity of alkaline AA batteries at low drain rates and can surpass alkaline performance in high drain applications ([i.e. digital](i.e. digital)[ ](i.e. digital)[cameras](cameras)) .\u003Cbr>The true advantage of NiMH batteries can be found in the cycle life (reuse after charging) . Typically NiMH batteries can be recharged hundreds of times, potentially allowing them to be equivalent to hundreds of alkaline batteries in total service over their lifetime. However, battery life is limited to 5 years or less. This can make rechargeable NiMH batteries a cost effective power source for many frequently used battery operated devices found in the home or office.\u003Cbr>Some of the advantages of the nickel-metal hydride battery are:\u003Cbr>• Energy density which can be translated into either long run times or reduction in the space necessary for the battery.\u003Cbr>• Elimination of the constraints on battery manufacture, usage, and disposal imposed because of concerns over cadmium toxicity.\u003Cbr>• Simplified incorporation into products currently using nickel cadmium batteries because of the many design similarities between the two chemistries.\u003Cbr>• Greater service advantage over other primary battery types at low temperature extremes operating at\u003Cbr>-20°C.\u003Cbr>Typical Applications\u003Cbr>The nickel-metal hydride battery is currently finding widespread application in those high-end portable electronic products where battery performance parameters, notably run time, are a major consideration in the purchase decision.\u003Cbr>History of NiMH Batteries\u003Cbr>Nickel-metal hydride batteries are essentially an extension of the proven sealed nickel-cadmium battery technology with the substitution of a hydrogen-absorbing negative electrode for the cadmium-based electrode. While this substitution increases the battery’s electrical capacity (measured in ampere-hours) for a given weight and volume and eliminates the cadmium which raises toxicity concerns, the remainder of the nickel-metal hydride battery is quite similar to the nickel-cadmium product. Many application parameters are little changed between the two battery types. (Table 1) compares key design features between battery chemistries. |  |\n\n\n| \u003Cbr>Nickel Metal Hydride (NiMH) Handbook and Application Manual | \u003Cbr>Nickel Metal Hydride |\n| --- | --- |\n| Energizer Brands, LLC. | 800-383-7323 | [www.energizer.com](www.energizer.com) |  |\n\n\n| Contents\u003Cbr>Introduction\u003Cbr>Battery Description\u003Cbr>Discharging Characteristics\u003Cbr>Charging Characteristics\u003Cbr>Storage\u003Cbr>Device Design Considerations\u003Cbr>Care and Handling\u003Cbr>Disposal and Recycling | Typical Application Features NiMH vs. Lithium Primary NiMH vs. Alkaline Rated Voltage 1.25V vs. 1.5V 1.25V vs. 1.5V Discharge Capacity NiM","cbCaidr7HkRW0OnW","https://ap.wps.com/l/cbCaidr7HkRW0OnW","pdf",420022,14,"English","# Introduction\n# Battery Description\n# Discharging Characteristics\n# Charging Characteristics\n# Storage\n# Device Design Considerations\n# Care and Handling\n# Disposal and Recycling","[{\"question\":\"Why are NiMH rechargeable batteries commonly used in portable electronics?\",\"answer\":\"NiMH batteries are suitable for devices needing frequent use and relatively high energy, such as digital cameras, GPS units, and MP3 players.
