iPad2 Battery Life Expectancy

I strongly doubt that the battery will fail in a cataclismic fashion within a period of six weeks. It doesn"t happen that suddenly. If you want to be sure, there are hundreds of external battery packs that will keep you going. Google is your friend.

Mophie makes some good ones.

The 12000mAH battery would provide a full charge for your iPad once it has run out, the smaller ones would only partially charge your ipad

As tonefox noted, the iPad battery won't simply "go dead" unless you can only use it for like 15-20 minutes max (from a full charge) right now (and then it's only a possiblility).

It'll simply last less and less over time, as it has done since you started using it.

What it the battery is, in fact, dead? Can I just plug in the iPad to a fully-charged battery backup device and operate it from that device?

It will probably not work if the battery is completely inop/dead.

If the battery is that close to dying, I would suggest you do not take it with you (or get the battery replaced beforehand).

Chris, thanks for this. The battery at this point has shown no signs of degradation whatever

Is there any way to measure the current capacity of the battery to take a charge that would allow me to predict what will happen between now and my return date. After we get back I'll be in a position to replace the battery with ease.

If it's showing no degredation, why would you replace it?

If it's lasting long enough to use between charges, don't do anything.

Your questions are beginning to smack of paranoia. We have given you every reassurance possible. The only catastrophic battery failure with which I am familiar is when the battery swells up and very slowly explodes the phone. The chances of this happening are on a level with winning the national lottery.

As has been said, if theirs nothing wrong with your battery now, there will be nothing wrong with it for the duration between now and the end of your trip. Don't forget to take your charger and any necessary adapters for local power points.

And, no one has yet answered the question about being able to use the unit with the battery backup the sole source of power.

Probably because virtually nobody has ever had the need to try it, and therefore, like me, cannot lay their hand on their heart and tell you. For my money, it would work fine. But again, the only case of catastrophic battery failure I have ever heard of has the side effect of physically destroying your phone (I haven't read of it happening to an iPad, and I've followed these forums for a few years), so it really doesn't matter either way 🙂

It depends on the battery fauilure.

Generally, a completely dead battery will prevent the unit from work even if power is applied, as the charging circuit will prevent power from being applied which may further damage the unit. this goe for most electronic devices (not just iPads).

If the battery is that bad, why would you consider even taking it?

You said there was no degradation so what's the worry?

If you are getting +6 hours of actual use between charges, it's not even close to the battery dying.

My iPad is almost 3 years old and it's fine.
