Hi.. I bought an iMac on 13th June and I had Energizer batteries in them , while it was new. I work on iMac for 16 hours a day. After 20 days , the batteries got drained. I bought 4 new Eveready Batteries and placed it. Now that new ones are getting drained in less than 12 hours. What the hell ? So, I need a permanent solution or need suggestion, what rating of rechargeable batteries or recharger I need for my iMac , so that those rechargeables can atleast hold 5-10 days. Im from India, so no Energizer here.
