Deceiving. Not 3 Volts battery.
This battery is advertised as a 3 Volts but it only has 2.61 Volts upon arrival. Deceiving. The original battery that I am replacing has 2.6 volts but the laptop has good 5 years or more of use, doesn’t make sense to replace with this supposedly “new” battery and doesn’t make sense why the sellers advertise something as 3 Volts if it only has 2.61 volts. Very disappointing. I don’t recommend.
