There are better rechargeable >batteries now that rival even lithium batteries. You have to be careful. Alkaline batteries produce 1.5 volts. Rechargable batteries are typically 1.2 volts. A radio might not care whether it is a 4.8 volt or 6 volt (assuming 4 batts in series) but a computer might...
