The company said the newcomer, Energizer Ultimate,
had been developed to meet the “growing need for high performance”. The battery will come in AAA, AA, 9-volt and C and D formats, and was in response to the growing use of “high-drain” appliances, it said.
However, consumers must dig deeper into their pockets for the new range. A pack of four AA batteries will carry an rsp of £5.19, compared with £4.29 for the same format in Ultra+. The company said the price hike was in direct proportion to its extra life.
