Battery replacement for Acer Aspire 5740G

  Florio 11:21 10 Sep 14

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)

The battery should be fine. A 0.2 volt difference is nothing to worry about as the laptop electronics will be capable of absorbing and functioning both above and below this.

Whoops finger trouble!! Same rule applies though.

Hi John

+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.

Hi alanrwood,

I obviously have little knowledge of that shorthand (or any other) so it looks like 'Whoops' again.

My maths was out anyway!!
