Anyone using the seidio extended 1750mAh battery?

I have voiced an opinion on this link before, and I will do so again.

BatteryBoss is an incompetent experimentalist who has more need for attention than for truth.[....edited for space....]

Some of the batteries he used were new and still gave such bad readings that they couldn't have been considered the "low" in a given batch of batteries. Needless to say, the subpar results of the new batteries is unacceptable at any quality control level. You usually get what you pay for.

I've purchased 2 $19.95 "OEM HTC" batteries off eBay that looked in every which way identical to the one that came out of my Eris so much that when I cycled them into my charging/using routine I lost track of which ones were the eBay ones. I believe these are authentic ones based on fit and finish and performance. They performed exactly the same as my stock battery near as I can tell.

That being said, I'll be purchasing 1 or 2 of these for my Incredible since I got rid of the other 2 when I sold my Eris. I believe HTC spent much more on their battery R&D than Seidio did so Seidio can keep their "your mileage may vary" batteries to themselves.

Here is the link to the batteries I purchased in case anyone is interested.

First of all, I don't care what BatteryBoss does or doesn't say. My original question still stands - can you explain to me - or find anywhere from a reputable source, how Seido can fit 450ma more into the SAME physical size battery, over an already top quality OEM cell? You can't, it's just science. They are playing funky rating games for marketing purposes - I wouldn't be surprised if the batteries were given their ma rating at 20C or some other unrealistically low number to jack them up.

So, we have established the TP2 battery is the same size as the Inc battery, yet holds 200mAh more. That sort o kills your whole argument here....
Not to say I do not agree...they may be playing games. I have not done the tests for myself. I will this summer (on lab grade equipment in a battery lab in one of the best Engineering colleges in the country/world).


EDIT: I did not realize the tiny difference. Having never seen a TP2 battery, I thought they were identical.

Hate to be so blunt, but you had no problem with it so here goes - you have no clue regarding battery chemistry. A high discharge rate sure could cripple a Li-ion battery - a discharge rate in the range of 9-10C, that is (many, many, many, many, many times what a phone can pull for those who don't know)! As for the charge rate, the phone controls the charge rate via software so long as it's charged in the phone, so once again your point holds no water whatsoever. That being said, it's still besides the point as I don't care about what batteryboss says.

Do you agree with me or disagree? You seem to have agreed in a very accusatory tone. I agree with everything you said. My point was that the people that sent the batteries to him may have used some cheap external charger that had no protection, or some other equally ridiculous thing. He then went and compared these to stock new, at most 2 or 3 months old stored at about 40% charge and probably at no greater than room temp or a little above.

Additinally, I do not care what batteryboss says either. However, there are people on this forum that listen to him, and they need to know what he did was not real science nor was it telling in any way. It was a bad application of bad knowledge which was then analyzed by bad statistical procedure.

Tell me about it! The thing that blows me away is it's not like I'm arguing that the sky is purple or anything. This is elementary, basic stuff , and all of it can be confirmed with a three second google. I'm floored there's so much information here; that's the one thing I do miss about windows mobile - the technical nature of the hardcore users on the forums.

Agreed.

Also, was it you who said that they were a battery scientist? What the Hell is that? MatSci? ChemE? Physics? Chem? EE with some chem background?

My credentials are (and I have stated this elsewhere to give some credibility to my statements <==yeah, I know this is the internet and I could just be saying this, but I am not. Promise. :p ) I am a Chemical Engineering and Physcis major at a major and very good engineering college. I work in a Materials Science and Engineering Lithium battery lab. My specific research has to do with recharging them after they have aged and have a really high internal resistance.

That may be so. My whole point has nothing to do with agreeing or disagreeing with the worth of third party batteries. My argument is that BatteryBoss is an idiot and what he did, while it may have yielded correct results, is not statistically viable and cannot be held as an authority. A "kitchen table" science experiment, maybe. Anecdotal evidence, sure. But not a rigorous test with proper error and statistical analysis.

You folks are funny :)

I will enjoy the battery discussion. In a few weeks, the dust/truth will settle and then I can see if the Seido is a good option. Timing is good, since I will know then if I will keep the Inc or get another Droid :)


added:

As far as batteries and background though, my under grad is Industrial Science and Computer Electronics. I also worked as a production manager for Enersys batteries. Does that make me an expert?

Wait, a second, those were stationary and large- motive power. Nevermind! ;)

BTW, HOT and NASTY process. Getting blood tests every other month and dealing with the acid and lead is a big drag :( At least I had an office to cool down in :)
 
Sooooo I've had my 1750 mah battery since i had my eris and in my personal experience it kept my phone alive longer than the oem battery. Once I got my incredible, i swapped out that battery for the 1750 because it was the same size as the eris battery, which therefore = longer battery life for the incredible. All i know is I'm happy and if you have 40 bucks to spare, you'll be happy too. :cool:
 
You guys are lucky...Droid out since Nov '09 and still no extended capacity slim battery for the Droid available from Siedio.
 
Hey guys, new to android forums but I thought I'd get a question in, as long as there is an extended battery thread.

I haven't gotten the incredible yet, but am about to buy it in a couple of days. Some spec sites report it as having considerably less battery life than the n1, but I can't figure out why..

Anyway, I was taking a look at Seidio's site, and saw that they are looking to make a 3500mAh battery for the incredible!

So my question is this.. sure, it will be large, and expensive, but I wonder if such a large battery would present heat issues or be potentially bad for the phone? Not too knowledgeable with batteries, so if someone would clear this up for me, it'd be appreciated.
 
I probably won't "clear things up" for you, but if they make this battery for the Inc then it would be tested. It will still dissapate power the way a smaller battery does it will just have that much more to give over an extended period. We seem to have some knowledgeable battery people here hope they will chime in for you. Welcome here and have fun!

A larger battery won't get as hot. Besides having more mass to absorb heat, it has more cells allowing less stress (draw) on each cell. Batteries get hot when you draw more than their rated discharge rate.

I've used many Seidio aftermarket cells. I think it's a travesty that people who have never tried them would 'dis them. To claim that the OEM cells are top notch is a guess. Moreover they are made in China. Seidio uses Japanese cells. I swapped a Seidio Extended on my last phone a WM Samsung i770. It goes for days. I've bought Seidios for Moto Qs with good results too.

I have two on order for the INCs we got last week. Guess I'll find out if their rep stands.
 
My Seidio 1750 will arrive Wednesday, which is a surprise because when I ordered it from Amazon on Saturday the estimated wait was two weeks.

That said, my stock battery is functioning much better now after five cycles. I used it slightly less today than I had all weekend, mainly because the newness is wearing off, but there was plenty of Facebook and email usage. Right now I am @58% after being unplugged for 9 hours and 37 minutes. That's an estimated 23 hours per charge. I know it would be more accurate if I waited until the charge was lower, and I will do the math tonight.

If anyone cares to compare statistics, here is the math I used. Perhaps there is a simpler way, but I don't know it and this only takes a minute.

9 hours & 37 minutes since unplugged = 577 minutes
Used 42% of charge (100%-58% present charge)

577 minutes / 42 % charge = 14 minutes per % charge... meaning 1% charge lasts an average of 14 minutes.

14 minutes per charge * 100 (total percent in full charge) = 1400 minutes per full charge

1400 minutes / 60 (minutes in hour) = roughly 23 hours per charge.

You're correct about your last point regarding current draw and heat, but otherwise completely incorrect. Lithium Polymer batteries don't have "cells" - our phone batteries are a single cell filled with a polymer gel. You're thinking of straight up lithium ion batteries like in laptops. For example, my thinkpad 9 cell extended battery is composed of 9 18650 cells. This is a different type of battery than our cell phones have.

I have tried them before I knew better (and sometimes, they can still be a good choice - just not in this instance where there is already a true 1500ma cell available for $15). I rocked a Seido extended in my Q for a long time. By the way, just so you know Seido doesn't actually manufacture the cells - nor does HTC. They both buy from an OEM manufacturer.
 
Thanks guys. Sounds good. If I find that I'm not happy with the battery life depending on what I do with the phone, I might get Seidio's 3500. All or nothing, I suppose! And sorry lars, my intent wasn't to dis the company, but my common sense told me to trust a company that I know of over one that I don't. I'll probably end up getting such a battery, unless there is another company that people prefer?
