MacBook Battery Life Lasting Time and Power
Macbook Battery Life Lasting Time
Apple claim that the 55 watt battery supplied with the Apple MacBook lasts for 6 hours. This has not been the case in my experience, I’m lucky if Apple MacBook Battery lasts 3 hours. When only really use the Macbook for Internet, email and general usage, no movies etc. However, i think this to be because of the batteries first charge. The general recommendation is to leave and overcharge a lithium battery for the first charge. The temptation to play with the MacBook was too much and I used it while the apple mac book battery charged.
Jere is the specification of the macbook battery,
Battery and power
- 55-watt-hour lithium-polymer battery (with integrated charge indicator LEDs) providing up to 6 hours of battery life
- 60W MagSafe Power Adaptor with cable management system
- MagSafe power adaptor port
Longer lasting…
I believe this is the reason why the battery doesn’t last as long as it should. A good point about the MacBook is that it shows you how long the battery is going to last by giving you an accurate lasting time and it goes down as you use it. Next time I will resist tempation and charge the battery fully before i use it.
Of-course this doesn’t mean that your Mac-book battery is completely knackered so it would still come in handy as a spare battery, if you have done a similar thing i would suggest purchasing a spare MacBook battery.
