just drop by to give feedback
mine was a compaq presario c794tu 6 cells battery 47whr
after refilled by Altrafield (only took 2 days) with a 56whr capacity, the cells are very high quality, now my laptop can last for a solid 3 hour with power plan and undervolt doing stuff like web surfing, paperwork, listening to music, 30% screen brightness and constantly downloading...which is AWESOME!

However due to my laptop bios design it could not recognise the full 56whr, only 47whr which prolongs longer endurance in long term as well bcoz of 85% max charge rate (reported 100% but in reality 85% = 47whr/56whr) that does not stress the battery to wear as quickly. (info gained after long replies LOL)

Thanks Altrafield for such great service and after sales service, definitely worth it and recommended for all =)
