Well, I don't want to carry around two spare batteries rather than one, I don't want my laptop to run out of juice early, and the fact that the "replacement" part has a markedly lower capacity speaks volumes of the quality of the cells it contains. I value my laptop enough that I don't want to fire an extinguisher at it! Jon -- SPAM BLOCK IN USE! To reply in email, replace 'deadspam' with 'green-lines'.

I've seen Acer laptops with three battery size options for the same machine ! Only machine cosmetic differences and price, separate them. -- Best Regards: Baron. |
