How to attenuate the battery degradation?

Im wondering how I can diminish the degradation of the battery, since its at 29 cycles and already at 95% health. My last notebook battery died within the 1st year, I dont want for it to happen again on this mbp.

My use is basically do what I want with the mbp, and when I now Im going to be near a socket for the battery to have time to recharge completely I plug it in. Thus there is an usual variation of, 40% left or something around 90% left, before I can connect to the mains.

 

Rechargeable batteries in general are going to last longer in certain conditions, certainly.

What helps?

1) Consistent moderate temperatures. Batteries kept somewhat cool undergo much less degradation due to chemical activity. However, in this particular application, there isn't much more that you can do. Apple specifies 50° to 95°F as the operating range, closer to 50° is going to yield better battery longevity.

2) Batteries that are used for deep occasional cycling have a tendency to outlast ones used for higher frequency shallow cycling. Your battery may have 29 full cycles, but ask yourself how many divisions of partial cycles do you have? The lesser the better.

3) Batteries have to experience a degree of usage. This means, that at least monthly, perform a full deep discharge/charge cycle (run near "empty", followed by a full charge). Rechargeable batteries that are rarely used at all, do suffer negative consequence to life.

I'd keep an eye on your battery within the first year while it's still under warranty. I have a 2009 13" MBP with over 400 cycles and my battery still reports 94% health. So it doesn't seem right that yours would have dropped to 95% already. I believe if it drops to 80% while under warranty Apple will replace it.

 

the decay of the battery has been rather recent in 2 weeks it went down from 98% to 95%.

I leave the battery to do a full discharge once a month, I was wondering if those micro charges would affect the battery life, I think a 40% left or less is ideal

 

battery health readouts can fluctuate up and down. a drop from 98% to 95% over a few days is not concerning on its own.

 

Indeed - I've had mine fluctuate between 95-99%, in both directions, over time.

 

So, if one buys apple care then battery is covered for 3 years, right? I think it is like this but I have a sony that came with complimentary 3 year support, but battery support is only for 1 year when I read their warranty documentation.

 

Mine hit 97% in about 10 cycles. Stayed there for the next 40 or so. It's now gone back up to 98%. Go figure.

I wouldn't worry about it too much.

 

This has been covered elsewhere - AC covers the hardware only, not consumables i.e. battery (which have an distinct 12 mo warranty).

 

I thought that did, because technically an LCD or even a hard drive could be "consumable" in the sense that use degrades them over time. I have had taken a Mac before to an apple store and the first thing they did was to check if my computer was still covered in the system with the warranty. I always thought the cut off was 300 cycles.
