instant.human Posted March 14, 2008 Share Posted March 14, 2008 recently, my macbooks battery will not load to 100% although the magsave is connected and all. coconut is telling me that its overall capacity is at 98%, does it mean its slowly dying on me, because the capacity is just not 100% anymore? istat pro tells me, its at 100% health, coconut says the charger is not connected although it is and istat seconds that its connected to power and yea, it just stops charging at 98%, as said. mini battery logger even tells me that its at 5140/5020, which would be an even greater capacity then it actually should have but i know that happens sometimes. im just a little confused by the different information i get. my mac is 16 months old, its a blackbook 2,0 c2d...

Puggsley Posted March 14, 2008 Share Posted March 14, 2008 I had the same issue after installing the 10.5.2 update on leopard. A permissions repair fixed the problem for me Link to comment https://www.neowin.net/forum/topic/625583-macbook-battery-stops-charging-at-98/#findComment-589270336 Share on other sites More sharing options...

TogaForComfort Posted March 14, 2008 Share Posted March 14, 2008 I see this all the time. The battery has a feature in it to stop overcharging and this sometimes cuts in to early. Also worth noting is: If the battery is over 95% full and you connect the adapter it will not charge. Again this is intentional. the battery needs to be drained past 95% then plugged in. This is to try and limit charge cycling which can reduce the batteries lifespan quite dramatically.

instant.human Posted March 14, 2008 Author Share Posted March 14, 2008 is that a new feature with 10.5.2? sorry for my dumbness but... yeah... ;) Link to comment https://www.neowin.net/forum/topic/625583-macbook-battery-stops-charging-at-98/#findComment-589270405 Share on other sites More sharing options...
CPressland Posted March 15, 2008 Share Posted March 15, 2008 is that a new feature with 10.5.2?sorry for my dumbness but... yeah... ;) No, it's hardware based so it's been there the entire life of your Mac. One thing you can try is a battery calibration. http://docs.info.apple.com/article.html?artnum=86284 I done this the other day and I'm getting at least another 10-20 minutes out of it now Link to comment https://www.neowin.net/forum/topic/625583-macbook-battery-stops-charging-at-98/#findComment-589271476 Share on other sites More sharing options...
instant.human Posted March 15, 2008 Author Share Posted March 15, 2008 hum, never noticed it. however, i did the battery calibration when i got it and 6 months later again. the "problem" is sovled, anyways, now, its at 100%.

Wannes Posted March 17, 2008 Share Posted March 17, 2008 It's not good to fully ( 100% ) charge your battery. Dell has been using such limitation for a while now. I'm sure you can find more about "overcharging" your laptop battery on Google but I am too lazy now. ;) Noteworthy: The Safari spellchecker doesn't recognise the word "Google".

instant.human Posted March 18, 2008 Author Share Posted March 18, 2008 hum, interestingly my battery is as of now fully charged at 100%, just as the last few days, i forgot about this topic, tbh... however, your note is interesting indeed.

Wannes Posted March 18, 2008 Share Posted March 18, 2008 My Macbook charges to 100% as well but Dells don't hence my point. :) Link to comment https://www.neowin.net/forum/topic/625583-macbook-battery-stops-charging-at-98/#findComment-589276721 Share on other sites More sharing options...
instant.human Posted March 18, 2008 Author Share Posted March 18, 2008 now i see. had a few beers back then. ;) Link to comment https://www.neowin.net/forum/topic/625583-macbook-battery-stops-charging-at-98/#findComment-589276762 Share on other sites More sharing options...
TogaForComfort Posted March 18, 2008 Share Posted March 18, 2008 is that a new feature with 10.5.2?sorry for my dumbness but... yeah... ;) As has been mentioned already it is part of the hardware, the Battery has a chip in it which manages this function (and a few others). My MacBook is currently at 99% and has stopped charging which is normal. Calibrating the battery will not fix this, as it's technically not an issue, it is by design.

TogaForComfort Posted March 18, 2008 Share Posted March 18, 2008 Mine stopped at 98%. anything between 95% - 100% is fine. If you are worried about the state of your battery and want to see how depleted it is use Coconut battery http://www.coconut-flavour.com/coconutbattery/ Link to comment https://www.neowin.net/forum/topic/625583-macbook-battery-stops-charging-at-98/#findComment-589276819 Share on other sites More sharing options...
