Depends on the battery, but for Ikea Ladda 2000mah end voltage is 1.53v, Sanyo Eneloop lite 1.51v, and Harmolatice is at 1.51v as well. Panasonic Eneloop 2000mah is at 1.53v , bootleg eneloop is at 1.45v. How ever once finish, it does not add more voltages. It will go on rest mode. Long term review should be out be september.
