I currently get between 2.5-3 hours of battery life out of my x505 depending on what I am doing with it, unfortunately this barely cuts it for me as my classes are 3 hours each (with 2 15 breaks). I can get through a class if I hibernate during breaks and have the screen on dim.
SonyStyle sells another battery for $300…I’ve had 20% and $100 off coupon codes, but it still was too much for me to spend on a battery, at least IMO.
I don’t believe in using non-OEM batteries becuase of quality issues and the dangers of exploding batteries (in some cases, rare, but possible). Anyway, I’ve had my eye open on eBay for batteries…i’ve seen real ones (used) sell for around $150ish + shipping…most fake ones sell for $95ish + shipping. I noticed a lister selling one for $55 + shipping. I bought it instantly. Funny thing is this seller has been selling them for $95, $75, and now $55…but he lists them all at the same time. I guess some people don’t search well and pay more then they should.
I figured for under $70 shipped, I was willing to take the risk. If it damaged my x505, I have insurance, I don’t really care.
Anyway, the item arrived within days (good seller) and I opened it up and surprisingly enough it was spot-on with the OEM one. I attached it to my 505, no wiggle room {good}, and plugged it into my 505. After it finished charging I decided to run tests…I unplugged the PC…checked the battery meter…5:56 minutes remaining! I almost dropped my 505! It took about 2 minutes for it to re-register the correct time. I got just about 3 full hours on the charge, exactly what I get out of the OEM one.
I don’t want to recommend the battery…I don’t want to be responsible if something happens to someone elses $3K machine…I just wanted to let people know my experience. Below you will find pics of the 2 batteries…
