Battery life dropped considerably on Mountain Lion.

The crazieness continues, after my battery went from 80% health to 100% yesterday I found it at 14% today on 318 cycles with only 35 minutes of life. I made a genius bar appointment and was told that it falls within standards but they would love to sell me a new one. I told them that my original battery has 844 cycles and still has 61% health but he just looked at me with a blank look on his face. Oh well, I'll just but in the old battery and see if it's software issue or simply the chip on my shoulder.

Umm, comparing old batteries with new ones may be apple and oranges. old batteries used Mercury (Hg) and all new beatteries do not use it. Wel.. not all, those made for medical devices still do, and I prefer those for electronics. What is the difference? Hg makes a battery last longer. Period. Batteries without are much weaker, but they are environmentally friendy. So I would not compare old with new battery.

New firmware released on MBas mid 2012. changed the name to 02 at the end

Be specific, are you talking about NiCad (Nickel Cadmium) NiMh (Nickel Metal Hydride) LiOn (Lithium Polymer) and what do you mean by old, and which type of batteries used Mercury

Answer please.

And just an FYI to help you, Mercury batteies are not rechargeable, did you plan an carrying a bunch around with you?

You clearly know little about chemistry

A mercury battery (also called mercuric oxide battery, or mercury cell) is a non-rechargeable electrochemical battery, a primary cell.

Mercury batteries were used in the shape of button cells for watches, hearing aids, and calculators, and in larger forms for other applications.

Due to the content of mercury, and the resulting environmental concerns, the sale of mercury batteries is banned in many countries. Both ANSI and IEC have withdrawn standards for mercury batteries.

Ok, so how to spot a narcissist, one of them is bellitleing questions or comments. "Mercury batteies are not rechargeable, did you plan an carrying a bunch around with you." and "you clearly know little about chemistry." Maybe, but know enough about psychology. And chemistry and physics, hence am happy at home with a perfectly working Macbook whcih i got to work by figuring out the problem. Have you?

As a matter of fact, my statement is accurate. Many older batteries contained Mercury. Today now, and they even add on the package (and your Apple Battery) " This battery does not contain Mercury." My statement never said that Mercury batteries are rechargeable, you did. It is called a Straw Man phallacy, in which you add words someone never spoke, and destroy that false statement you yourself created. Critical thinking 101, and basic education. A judge usually shuts a lawyer up- or the oppsoing one does. However, in some psychological models, some people thrive on trying to establish superiority by belittleing others with negative comments. They also flip if contradicted or proven is some form of error.

Apple batteries today, as in current 6400 or 7800, are quite different then batteries designed in the early 2000s. Should you wish to find out, buy a few and cut them. One safe bet is the older ones contained restricted or toxic chemicals that today are not allowed under the Rechergable Battery Recycling Act and so on. Anyhow, met quite a few people with G4s that are working fine after 1000 cycles, and never met such a person with a more recent battery, as in last 5 years. I would not compare old batteries with new ones.

You really don't have a clue, thanks.

I have Macbook air 11" (mid 2011). After Mountain Lion installation battery lasted around 2.5 hour which was very poor. In my 4th attemp of ML clean installation I managed to get back 4-5h battery life. My current settings are:

- fresh ML installation 10.8.2

- no flash (I use google chrome for flash content)

- disabled notifications (calendar, mail,...)

- disabled notification center (you can find on Google howto do this)

I'm very satisfied now with my Macbook....

Actually I do, but I do not play your game. You hunt and provoke, gauging for a reaction, liking to catch people off guard. Those with your narcissistic doses always do. It is what you do and have done since you first posted. I do not waste time with someone as yourself. Go poke on others around you, and not on a forum.

Anyone following Boeing's problems? It is battery related, Li-Ion. One can be assured that the qualitative controls and engineering standards for those batteries are much higher then laptop batteries. Yes two nearly caught fire and nearly destroyed two aircraft. A long way to say that under certain conditions, lithium ion batteries stop performing out of nowhere. In Boeing's case, replacement is not an option as the problem is not solved to begin with.

A History of Laptop Batteries

The info I'm finding suggests that each batery technology was adopted due to lower weight, and higher capacities.

Cadmium had heavy metal drawbacks that made the comparable NiMH win out. and 50% more power:

Li-Ion appears to have been in existence since the 70's, yet only became practical recently? (The Li-Ion polymer improvement being key, perhaps?)

No mention of Mercury.

Perhaps mercury was a necessary contaminant of NiCd and NiMH like arsenic use in semiconductors or had an augmentation effect like lead in gasoline?

I did see articles about the headaches photographers experienced when their powerful mercury (single use) batteries were replaced by numerous other inferior choices. Not much on laptops though.

Good stats here including a surprising list of variants of the Li-Ion:

NiCad

NiMH

Lithium Ion

Don't waste your time with facts Beisarius is a 'special' kind of expert.

Do not presume to instruct me, it's your fantasy only.

Many of us are following this discussion through e-mail and don't want to waiste our time reading this off-topic, personal mudfight. Therefore, gents: please stop this needless arguing.

You tell 'em, Jerry!

yes please guys, could we hear some more reactions to Franc iPhone's discussion of the seed version of 10.8.3 on page 201 of this very long thread. thx

Hear, hear, Davey.
