BatterySavers.com offers a battery comparison chart showing common battery types, ranging from size D to 9-volt batteries, along with their typical flashlight drain times and capacities. Duracell.com publishes several battery comparison charts for all-purpose batteries, flashlight batteries, power reserves and rechargeable batteries with recommendations for its specific battery lines.
Duracell.com’s all-purpose battery chart shows recommendations for different battery types based on the recommended use of each type of battery. For example, it recommends its Quantum brand batteries for powering portable electronics, remote controls, toys and wireless keyboards. By contrast, Duracall recommends its rechargeable DuraLock batteries for high-drain items, such as high-powered flashlights and video game controllers.
