This increase is the same as the Eneloop Pro model. The Plus, however, also has an overheat prevention function that stops the batteries from getting too hot. This is ideal for toys and other products children might use. The Eneloop Plus comes in packs of four batteries with a portable wall charger. Sanyo suggests that these make a good choice over standard rechargeables especially when used with high-powered portable devices, like cameras, their flashes, or even flashlights. All Eneloop Plus batteries have white casing to distinguish them from the Eneloop pro.
