Can I replace a laptop battery with one that has the same voltage …

Make sure the battery physically fits in your machine. The voltage is the same, so that is fine. The power output is lower, so it will not last as long without AC, but the charging circuit should charge it properly. Some batteries have chips to match the battery with the computer, so watch for that. So long as it fits properly, you should be fine.

I have basic question about connecting two batteries of same type (ie of same voltage and same capacity, say 12V and 100Ah) parallel. ... For the parallel case, the power delivered to a 10 ohm load would be 10V * 1A * 20h = 200Wh. In series with 10 ohm load, it would be 20V * 2A * 5h = 200Wh. ... Battery capacity at different loads. 0.

Rechargeable Batteries — compared and explained in detail

Voltage. At 1.2V, no other battery has less voltage than NiCd''s. (For reference, alkalines are 1.5V.) This is generally not a problem, but it does mean that flashlights will be dimmer, and devices that need 4 or more batteries might not work at all. Voltage Drop.
