Treo 680/750 2400mAh Extended Battery

Best Treo 680 Extended BatteryFollowing the introduction last week of the spare Treo 1200mAh battery for the Treo 680/750 the Treonauts Accessories Shop now finally also has the Seidio 2400mAh Extended Battery for Treo 680 and Treo 750 Extended Battery which offer up to twice the capacity of the standard battery.

The Extended Battery kit consists of both the battery and a replacement battery cover (below) which is required to accomodate the larger sized 2400mAh battery (about twice the thickness of the 1200mAh).

The battery cover – which perfectly matches the finish of your Treo – fits easily sliding over over the large capacity battery.

Although the battery cover adds some 4mm to the thickness of your Treo (below) which makes it somewhat less ‘pocketable’ I personally found that it actually improves your grip and feels very comfortable in your palm.

Having said this the most important benefit of the extended battery naturally remains the fact that it offers so much more power – ideal if like me you use your Treo extensively throughout the day – and I guess that the bulging battery cover is a small price to pay for this.

I have not yet had a chance to test the fit of the extended battery with multiple cases but I can however already tell you that it will fit perfectly in my favourite SPE UltraSlim Executive Pocket Pouch where the added thickness of the battery cover fully ensures that it will not slide out.

If you have a Treo 650/700 please also see my previous post Treo 650 3200mAh Ultra Extended Battery or Treo 700 3200mAh Ultra Extended Battery.

Treonauts always have more power

I, too, received one of these in the mail a couple of weeks ago, as I use my 680 constantly for my business. I have found that my battery life has increased substantially, but there are still several issues.

First of all, the battery memory seems to be screwy, as twice thus far, I've had a handset shutdown due to a "dead" battery, even though the unit showed about a 40% charge.

Secondly, the cover does not stay on nearly as well as I would like. It dislodges when I remove it from my holster. Granted, I should probably get another holster, but I expect a little more of a quality fit than I've gotten from this product.

Thirdly, the form factor isn't nearly as important to me as to most people, but I've found that my window-mounted holder no longer can accommodate my 680, nor can my Mobo wallet case. However, my ProClip dash mount works quite nicely with the added battery bulk.

I agree that the battery life has increased greatly. I have also seen the same dead battery message every once in awhile. I can only assume that it's a minor bug that will work itself out as time goes on - Maybe through a bug fix from palm?
The only concern I have is that I wish there are more Treo cases out there that can accommodate the new battery cover. There are a lot of cases out there that I would like to order, but none of them will accommodate the new battery cover.

I received one of the early releases of the 2400 battery. I also had problems with the cover that didn't click closed properly and kept on sliding off. I contacted Seidio and requested a replacement battery (overnight) and they obliged. The new cover fits fine but I must say doesn't seem nearly as well engineered as the original battery cover. After about a month of use I'm also finding that the replacement cover is more prone to getting scratched than the original cover. However, the battery is great and is what I would consider to be a "normal" life for this kind of phone. I have also had two instances when the battery meter suddenly dropped and the phone re-set itself. However, I've not had that problem in the past two weeks or so. Maybe it's fixed itself.

I have the 2400 mAh battery that I bought for my 650. Can I just get the cover in crimson?

by Peter | Mar 10, 2007 5:36:54 AM

I bought for my Treo 680
2 x 2400 mAh Battery with Arctic cover.

The batterie cover fits perfect but it does not "click" in place if you close it. It is like
always unlocked and with a little slide down
of your hand if you hold the phone, the batterie cover just opens.

As I bought two I tried both and both don't
"click" lock if you slide close the cover.

Also the bigger batterie is not 100% horizontal
if it is inserted and cause a little slope which
is only noticable if you look very closely, but
the cover does not press against the batterie so
there is enough space.

Anyway, it seams there is a production problem of
the locking mechanic for the Treo 680 batt. cover.

What do you think the problem is with the "dead battery" message coming on with the Treo 680?

by Glen Peters | Mar 12, 2007 2:39:08 PM

Where is the COPPER version? I agree with Ron as well, can I just buy the cover?

Can anyone tell me if the Palm cradle can charge this new extended battery in it's extra compartment?

by Steve Anderson | Mar 15, 2007 11:23:01 AM

I just got the extended battery, and so far I don't see any problem with the extra cover. Of course, I haven't had it long enough to have "dead battery" issues yet.

I can confirm that the extended battery does charge in the Palm cradle's extra compartment. However, the extra bulk makes it so that the Treo itself won't fit in the cradle with the extended battery in place.

The Treo with the extended battery also won't fit in my new SENA flip-front case, which is not surprising. Do you have a list of cases the will accommodate the extra bulk? The only one I've seen mentioned is the SPE UltraSlim case, and some readers seem to have issues with the quality of this case.

Ron asked a few weeks ago, "I have the 2400 mAh battery that I bought for my 650. Can I just get the cover in crimson?"

The answer to that seems to be NO. Seidio markets the battery with a "free battery cover" but apparently it is impossible to buy the cover from them (or anyone else). Guess the market price is "free."

I too have a 2400mAh battery I bought for my 650 and would like to use it in the 680. I'll probably get the "680" battery just for the cover and use the 650 battery first with it.

Does anyone see a problem with using the 3.6V 2400mAh battery with the 680 when the device seems to call for a 3.7V battery?

I just upgraded my beloved 650 into a 680. While I love swimming in triple the on-board usable memory, I am anticipating problems with the standard battery's lack of live and just came to a realization:

One of the ideas is that the 680 has a little more ergonomic shape, a little tapered and sloped towards the keyboard end, etc... BUT THEN, TO MAKE IT WORK THE WAY WE'VE COME TO EXPECT BASED ON THE 650, I NEED TO GET A NEW THICKER BATTERY AND COVER THAT SCREWS UP THE FORM FACTOR.

Nice one, Palm - once again, you guys prove you're out to lunch. Of course, for those who are coming into Treo new without the HINDRANCE of experience with previous models, they won't have the background for comparison. But then, my old Nokia candy bar phone will last a week easily with regular use, so battery life for a Treo will never compare given all we do with a Treo.

But, c'mon Palm, we Treo users are not just phone users, we're doing more, and when you design your "form factor" the battery horsepower and size must be taking into consideration. For the power users you continue to neglect with your incremental "upgrades" and pandering to other markets (ever hear the saying "a bird in the hand is worth two in the bush?". Evidently not) most power users will tell you that performance trumps aesthetics, if you must force us to choose (bigger screen, more battery capacity, more memory, more connectivity, do you see the theme here of "MORE"?. I don't need a "cute" phone, I need a productivity platform.

Sadly, the competition is ramping up its assault on the market space by increasingly offering BOTH performance and aesthetics - imagine that, it is possible. I love my Palm, but you guys seem bent on driving me to your competition who appears to better understand me than you do.

Is anyone using this phone cover with the 650 holder? If so, does it fit?

by jose mora | Mar 21, 2008 9:31:19 PM

I want to buy a 2400mhn extended battery or plus color metallic color ,an skin(silicone)cover for the treo with the extended battery and a jack 2.5 for use 3.5 jack earphone, i live in Chile my code is 4290003, what can i do?

by Alex Ethridge | Oct 19, 2009 12:23:30 PM

In reference to the cover not fitting properly:

This might be a problem not unique to the 2400 battery because I have the 1600 battery and exeprienced the same problem with its cover.

This is how I fixed it if I remember correctly:

I closely examined how the back slid on and how its clicking into place compared to the Palm back. I noticed the difference in the way it clicked (or didn't quite). I measured the back with a caliper and found the Seidio back was a few thousandths of an inch longer. I sanded those few thousandths off the top end with some fine-grade sand paper which then allowed the latch end to slide up far enough to fully engage and it then worked equally as well as the Palm-branded back.

I'm sure Ken has an answer to his question; but, no one posted it so, for the benefit of other readers, the Palm cradle will accommodate only the stock Palm battery.

I also have found after-market cradles that I could use with the 1600 battery and, the way it's designed, I'm sure will also accommodate the 2400 with a very, very small amount of Xacto knife work--provided the back is removed (battery still in). Anyway, that's the way I got my 1600 to fit.
