I'm evaluating a few battery packs to use for Macbook Pro & my
Thinkpads:


a) Tekkeon 3450

b) Energizer XP18000 .  Refer to
    http://www.amazon.com/Energizer-XP18000-Universal-External-Netbooks/dp/B002K8M9HC/ref=sr_1_1?ie=UTF8&qid=1358602353&sr=8-1&keywords=XP18000

c) Incredischarge .  Refer to
   http://www.amazon.com/Incredicharge-I-18000-Universal-External-Netbooks/dp/B006ZB051W/ref=sr_1_5?ie=UTF8&qid=1358601268&sr=8-5&keywords=XP18000

d) Tursion . REfer to
   http://www.amazon.com/Capacity-33600mAh-Portable-External-Notebooks/dp/B0063KXZQ2/ref=sr_1_4?ie=UTF8&qid=1358602353&sr=8-4&keywords=XP18000

Q1:
Read in amazon that Energizer's XP18000 won't charge a Macbook even
when it's connected to AC power (so I guess the AC power is charging
the XP18000 while the XP18000 is charging the laptop ? )

Q2:
Which one of the 4 has the surest-to-work supportability/ compatibility
in charging a Macbook Pro (esp the 13.3" Retina model) ?

Q3:
Which of the 4 has the longest battery life & providing longest charging
hours to a laptop?

Q4:
Macbook Pro's battery can't be removed/replaced by consumer right?
Has to be done by Apple?

I don't live in USA, so if the item is damaged/need to be sent for warranty,
it's going to be very troublesome.  Live in a formerUK commonwealth country

So in answering Q1, need to assess if the other 3 batteries
would charge the laptop when the battery is connected to
AC.

I live in a country using 220-240V (13A UK power point), so need to be certain
I can charge the batteries in my country

Q1 - this isn't strictly true, you can charge a MBPro from the Energizer but not using the Airline Adapter cable as the Airlink's MagSafe connector doesn't connect to the MBPro's charging circuit - it's fine for using the MBPro during a flight by directly powering the device but if everyone wanted to charge at the same time as using there'd be a big increase in current draw so the feature is missing by design.  I'm guessing you may have misinterpreted the info from here

There isn't a cable licensed by Apple to both charge and use but they are pretty easy to make.  See this description and the links from it.

Q4 - The battery isn't designed to be replaced by the end user but it's pretty easy to do it, there are loads of tutorials and videos available you just need the right screwdriver and a replacement battery which are also easy to come by (and work with any power supply).

As I pointed out in your earlier question, the manufacturer's produce their chargers for a worldwide market so the adaptors can handle voltages between 110-240 with the same output.

I'm not good at doing such DIY;  is there an online store that sells this?


for a Macbook Pro to be used on average 5 hrs per day, can the battery
last for 1 year before it's due for replacement?

Does Applecare/warranty covers the battery?
