For the first time, I have to replace the battery on my laptop. I ordered a new battery online, but the one that arrived this morning doesn't have the same number (AS07A41 instead of AS07A31), and the voltage is 11.1 instead of 10.8. Can I safely use the replacement battery that I have been sent, or should I send it back to the seller? (I'm assuming that he gave me something compatible)
+1 is shorthand for "I agree with you", not that your figure was incorrect. The difference is minimal anyway and as you point out the internal voltage/current control circuitry would handle this anyway with no difficulty.
