The E235 series (E235系, E235-kei) is a DC electric multiple unit (EMU) commuter and suburban train type operated by East Japan Railway Company (JR East). The commuter variant was introduced on Yamanote Line services in November 2015, and the suburban variant entered service on the Sōbu Rapid and Yokosuka Lines on 21 December 2020.
Used for idling when the battery state of charge (SOC) is high. Cruise mode—The vehicle is cruising (i.e. not accelerating), and the ICE can meet the demand. The power from the engine is split between the mechanical path and the generator. The battery also powers the motor, whose power is summed mechanically with the engine.
The E233 series (E233系) is a commuter and suburban electric multiple unit (EMU) train type developed by East Japan Railway Company (JR East) from the earlier E231 series and the E531 series design.
The DieHard brand is also used on hand tools, power tools, battery chargers, booster cables, power inverters, alkaline batteries, tires, work boots, and the batteries for Craftsman power tools. Battery chargers were initially made by Associated Equipment under the "608" model prefix, and then later Schumacher Electric under the "200" model prefix.
An earth battery is a pair of electrodes made of two dissimilar metals, such as iron and copper, which are buried in the soil or immersed in the sea. Earth batteries act as water-activated batteries .

Zinc–air batteries have higher energy density than many other types of battery because atmospheric air is one of the battery reactants, in contrast to battery types that require a material such as manganese dioxide in combination with zinc. Energy density, when measured by weight (mass) is known as specific energy. The following table shows ...
