The Eneloop CC55 Quick Charger Kit from Panasonic contains eight Ni-MH AA batteries with a capacity of 2000mAh and four AAA batteries with a capacity of 800mAh. The batteries have been pre-charged by solar power, so they are ready to use out of the package. The included CC55 charger has four charging bays with individual LED charge indicator lights, which shows how much each battery has charged. To charge a fully depleted battery, it can take between three and four hours, and once all the batteries are fully charged, the charger will automatically shut off for overcharge protection.
Within the charger, the batteries can be placed in any combination by mixing the AA or AAA's, and the configuration won't affect the charging times. Because of their slow self-discharge, even after 10 years in storage the batteries maintain 70% of their charge, and can be recharged up to 2100 cycles. In addition, the charger has an integrated, retractable, American AC plug, but can be used anywhere in the world because of its universal 100-240V capacity.
