Hi there Friend ! What 8 cells battery you have got, and from which seller? It is either your battery needs a few power cycles to get to its' full performance, or maybe you have received a battery with the different power cells (not SANYO) : e.g. your original battery was SANYO but that new 8cells could be SMP ? :P
If you would look at the PDF Hardware Maintenance Manual for Lenovo G505S laptop (easily found online, contains many FRU replacement parts descriptions/IDs, useful) you will see that - even for the official G505S batteries, there were three manufacturers: Sanyo, LG, SMP (Simplo). According to some tests, Sanyo are much better than SMP/LG. Please look at the attached picture - it contains a small review of the battery cells (could be expanded) my 8cells battery is Sanyo, and its almost twice longer battery life! Mike result is ~1.5x longer, but he haven't told me who made his cells, or I forgot what he has replied to me and couldnt find. Guess its a bit of a lottery... If your battery would not perform better after a few power cycles, you could try getting another 8 cells battery, preferably from another seller - for a higher chance that these batteries would be from the different batches with the different internals - and we will see However, if you would look through this guide above, there are some more worthy investments: in example, AR9462 wireless network adapter from ath9k family - does not need the binary blobs, runs on 100% open source and supports 2.4GHz/5GHz and even Bluetooth, works fine even at the Stallman-endorsed Linux distros. Ideally, batteries should be bought after you have got everything else. By the way, 2-3 times per year you could get 10-20% off AliExpress coupons for a great real discount Retyped table from the attached image (so that it will be searchable through the Internet) : Laptop batteries for | Model -- ___ | ______ | Stated __| Max energy capacity | Max energy capacity __| ______| G505S and other __| battery cells | _______| capacity | by design __________| after 3 months of _____| ______| compatible Lenovo | manufacturer | Voltage | in mAh _| (as seen by ________| heavy usage _________| Rating | laptops __________|___________| _______|_________| Ubuntu Linux OS ) __| ____________________| ______| official Lenovo ____| L12S4E01 -- | 14.4V | 2900 mAh | 3.8 Wh ____________| 3.5 Wh (94% of design) | medium | 4 cells battery ____| SANYO ____|______|__________|___________________| ____________________| battery | (older revision) ____|___________|______|__________|____________________|_____________________|______| official Lenovo ____| L12M4E01 -- | 14.88V | 2800 mAh | 3.8 Wh ____________| 3.1 Wh (81% of design) | bad__ | 4 cells battery ____| Simplo _____|_______|__________|___________________| ____________________| battery | (newer revision) ____| Technology |_______|__________|___________________|____________________|_______| __________________| ( SMP ) ___|______|__________|____________________|____________________|_______| 8cells G505S battery | " Replace | 14.4V _| 5200 mAh | 6.3 Wh ____________| 6.1 Wh (96% of design) | the best | by AliExpress seller _| L12L4A02, |______|__________|___________________| ___________________| battery !_| MX (HK) LTD -- _____| L12L4E01, |______|__________|___________________|____________________|________| Ming Xuan ________| L12M4A02 " |_____|__________|___________________|____________________|_________| __________________| -- SANYO |______|__________|___________________|____________________|_________| NOTE: battery model number is L12*4E01, where * letter means the manufacturer of battery cells. in L12S4E01 , S means SANYO, || in L12M4E01 , M means Simplo Technology ( SMP ), in L12L4E01, L means LG chemicals || Older (official) batteries were usually SANYO, newer (official) batteries are usually SMP, sadly.
