Longlife Accus: Ni-MH product range with longlasting energy for all standard devices. Ordinary rechargeables get discharged during storage and loose much of their capacity. With VARTA Ready2Use rechargeables you won’t have much of a capacity problem. Once charged these new batteries still retain 80% of their capacity after one year of storage. Please note: VARTA Ready2Use rechargeables do not require a special charger and can be used for all applications.
