Sanyo (http//us.sanyo.com) has released new AA- and AAA-size “eneloop” rechargeable batteries with approximately 500 more charges than previous eneloop batteries. The batteries are charged and ready to use and will maintain approximately 75% of their charge up to three years, according to Tom Van Voy, vice president and general manager of the Sanyo Digital Solutions Division.

The new eneloop 1500-cycle batteries are available immediately at Costco Stores nationwide. The combo-pack containing the 4-position charger, eight (8) AA batteries and four AAA batteries sells for US$25.99 at Costco.

The eneloop batteries in the Costco combo-pack come in two shades of blue and two shades of green. The colors provide added convenience making it easy for consumers to “pair” the batteries in devices and in the charger, says Voy.
