I have an old 15" MacBook Pro (Rev E). It uses "A1175" battery, which unfortunately is known to be notoriously bad at retaining charge. My battery has been 100% dead for some time and need replacing. Although Apple would like to charge me £99 for the pleasure. However, I have found plenty of compatible third party batteries on ebay (see below). The specification and feedback looks good and they are a fraction of the price Apple are charging (just £29). http://cgi.ebay.co.uk/Battery-Apple...pBatteries&hash=item3f05b46fc2#ht_5054wt_1135 Does anyone have any experience with these third party batteries? Are they safe? Do they do the job?
