Even if you get 2/3rd, hell even 1/3 the battery life of the OEM HTC, two of them would make a good emergency back up to have in the car, on a trip etc for when maybe you couldn't use a car charger or get to a wall jack.

That said, for you guys that have these, whats the average charge time for these batteries on this charger? I just got mine in the mail about an hour ago, been on the charger about an hour now. I'm still looking at a pretty pink'ish/red'ish charging light, no green yet!

I freaking love eBay. Not only am I going to get these both as well, but I also got 3 data cables (one for each of my vehicles that has a usb port, and one for the computer) and a car charger (for the one that doesn't) for under $8 shipped. It's just ridiculously cheap. There is such a wicked markup on electronics that it makes me sick.

3 to 5 hours. No joke. If you want faster charging use the phone to charge. Not that big a deal to me.

We have a winner... these batteries have no overheat protection and they also lack the circuit that protects it from leaking/exploding. Now this shouldn't just magically happen but it can and if it ever does with no protection whatsoever in place it could go bad. You could suffer a mild scare up to and including losing an eye if the thing blows up in your face while you're holding it against your ear. It would cost them way too much to install any type of protection on these batteries and they wouldn't make any profit, in fact 90% of all cellphone batteries that blow up come from ebay Chinese sellers. I'd be careful not to try and save 30-40 bucks and end up losing your phone or something much more valuable.

Also side note thee batteries are not 1500mah, they might claim to be but you'll be lucky if they hit 1100 when you measure them, all chinese knockoffs are hundreds of mah underpowered.

Easy to understand why, one has circuit protection the other one will just heat up to the point of either exploding or leaking. Not to mention their power rating when compared to name brand OEM batteries. People still don't get it but you get what you pay for.

Think I'm full of it?
http://gizmodo.com/5539192/a-cellphone-exploded-in-my-face

That battery actually had protection and it still failed somewhat he did crush it with a carseat could have been a bad batch too, but these have 0 protection so yeah...

Plenty of cases online just Google some more here is another.

I bought the batteries and charger just to have the wall battery charger. I already had a spare oem battery for the hero, so I now have 4 batteries. I am skeptical to use the knock off batteries so I'll stick with the stock evo and stock hero battery.

The wall charger is convenient and works. I charge over night so the long wait to charge is not inconvenient. It was a bargain.

all the claims you are saying about this battery package...about it not having any protection, etc...what source are you quoting from that states this particular battery package that everyone is getting offers no protection from overcharging, etc..?

you do know OEM batteries have imploded and exploded too? this does not only apply to generic batteries.

batteries exploding are not common and are usually caused by human error. the gizmodo article you listed does not say the battery was a generic so why post that here? and from looking at the photos and the guys story, it seems more human error on his part more so than the phone. i mean if the phone was on a table or seat and just blew up thats one thing , however this phone the guy had slid in between the seat, the seat slid back crushing the phone and stressing the battery pack... i can see why the battery did what it did...

i have been using this ebay battery system for a few days now. i had the battery in the phone and had the phone charging in the car. it got really hot in the vehicle and the charging was suspended due to heat. i didn't meant for that to happen and why the phone was in the car is not important to this post. my point here is these batteries and many other generics have over charge protection. its super cheap to install this tech into the battery packs. some of these oem batteries are made on the same lines as generics. simply quoting unfortunate articles form the internet does not really prove your point about THIS particular battery package.

the other article you mentioned does not specify if it was a generic or oem battery. the report also stated 83 reported cases of battery explosions.. out of how many phones are out there? millions? laptop batteries explode, car batteries explode.. etc etc.... this is not only unique tro cell packs...

believe it or not, todays battery tech is very stable as long as consumers follow good safe usage tips, which your last article spoke about. the consumer needs to understand the dangers of these cell packs and how heat and physical damage can make the cell pack unstable.. this applies to OEM as well as generic...

what if these batteries were 50 bux? would this make you feel better purchasing? what if htc sold their batteries at 12 dollars a piece? would you automatically call them cheap knock offs?

people should stop slinging negative posts about inexpensive batteries. this tech is so old that the companies have made their profit on the tech and can sell batteries for cheap.

Thank you marctronixx. From the bottom of my heart, thank you. I hate it, absolutely HATE it when people post false/misleading/ or completely unsourced information solely with the intention of scaring other users. Nothing angers me more on a forum.

Thank you for, ONCE AGAIN, making sure that type of post doesn't sit unchallenged. Very well done.

I'm actually on your side marctronixx, but if you're asking SebastianX for his source on his information, I have to ask your source. How do you know these batteries (which I have also ordered, btw) DO have protection?

im glad you asked the question..

of the tops, the ebay ad states there is fault protection. they would be doing false advertising if this was not true.

"but marctronixx this is ebay, people lie on ebay all the time.."

ok ok ok... so lets say the ad did not mention this (which would be foolish..)

Lithium Ion technology is highly unstable! period. you can google that and read it. in order to harness the energy Li-Ion cells produce, you MUST.. MUST... MUST have safety protocol's i place, otherwise the moment that battery pack reaches a certain temp the pack can produce whats called "thermal runaway" at the worse extreme of the breakdown of the cell pack.

this is what happeed a few years ago when dell had that recall on the sony cells in the laptops that were combusting. when the ion material breaks the confines of the structure and mix with air, its explodes. sony , who made those batteries, stated there were some bits of metal left in the cell packs during manufacture and a certain batch of ion packs had to be recalled...

and SONY is a BRAND NAME supplier of batteries and they had that big media circus over it.. im sure you guys and gal remember that. one exploded on a plane, one battery combusted in a meeting (i think its on youtube)... which proves even the best batteries can have issues..

"marc your digressing..."

ooh yes apologies...

ok.. yeah,so in order to harness that power lithium ions can produce they need to have safety precautions in place. this is paramount. you can not produce these packs without them.. lithium ions and heat do NOT work together (think old VW bug magnesium engines and water!). some packs mayhave more additional features but they ALL have some. most of them have circuitry that senses when voltage (and the heat associated with it) gets to a threshold. this circuit kicks in and stops charging.

there are other features (vents to let heat escape for example) incorporated to prevent overcharging, high current draw (this can cause heat really fast), etc. these are all required when handling/manufacturing lithium ion battery cells. Lithium ion tech has been out for over 25 years and its matured battery tech. all the companies know the pros and cons to it.. its no secret. the smaller the battery the more robust the prevention circuitry needs to be im plemented as the area is smaller and therefore heat will increase, not to mention a mobile phone's hot CPU right under the battery!

and as a unscheduled test, i had left the EVO in the car this past sat. the heat in the cabin was in the 90s as it was 97 outside. i left the phone charging via cig socket which is more current than laptop charging.

naturally the phone was indeed warm/hot. the battery pack had stopped charging due to high temps and the flashing light on the evo (all htc handsets i have had do this amber flashing light) was blinking to let me know the phone was too hot to continue charging...

search the net and you will find this info. overcharging/over-current/overheat protection is a MUST....

this info is all over the internet.

Switched out the OEM battery and been charging the EVO from the adaptor's usb port. No problems so far - love the purple night light on the adaptor.

Got mine a couple days ago. They take about 3 hrs or so to charge. I started putting one through its paces and it didnt seem to discharge any faster than the stock battery...not sure if that trend would last all the way down to 0% or not though. Im guessing you can probably only charge/discharge these a fraction of the times you can with the OEM Battery, but thats just a guess.

Either way, for 11 bucks, cant beat this for a backup battery unless it explodes in your face

Old news but good for newbies to see I guess.

Have been using these since my Hero. My wife and I have 4. At least 40 people have gotten these and been happy. Search for threads for more if you are interested.

Just got mine in today, you may try looking for Battery's for the TP2, mine had stickers saying they were for the TP2 on them.

Yes, they still work in the Evo, aswell as the Hero.

They look promising, and if they don't last as long as the OEM one, oh well. was only $10

It is an awesome deal, but I can't bring myself to even spend 10 bucks for extra batteries. I was going to a few weeks ago when this forum had me all nervous about battery life, but mine has been excellent. I'm waiting on a bundle that has other stuff that I could use with it. If some seller had a bundle with the batteries + charger, a micro-HDMI cable, a few screen protectors, and a dual outlet USB car charger (the kind where I supply the cable), I'd be all over it.

But they do. Again, this is old news and many people have gotten them and have been using them. Just about everyone says the same thing. These batteries last just as long as the stock battary.

I know a lot of other people have chimed in but I just thought I would echo what everyone else is saying. If you need a spare battery (or two) this is a great deal. I can tell no difference between these batteries and the stock Evo battery. A charger that does battery and phone at the same time with 2 batteries for $11 shipped is gonna be tough to beat.

Can i use my original phone charger to charge these batteries from ebay or do i have to take them out of my phone and use their charger?

I rather take an extra battery than an extra charger.

You can charge them fine right in the phone. Just like you other battery, only black.

Default Battery Issue Solved for $10.00

I was having a problem with my battery going from 100% down to 80% very rapidly like most people were having. Well, today, my two batteries that I ordered from eBay with a charger came in. I charged one of them completely with the wall charger, swapped my battery out and it stayed on 100% for about 10 minutes before going down. After some calls and data use (downloaded about 25 MB of data), it is at 88% after about 2 hours.

Not sure if I will get better battery life but so far, it seems like it.

Any links you can provide or details on purchasing the battery?

Mine came in the mail today. I've had the battery in the external charger plugged in for about 3 hours. The light shines a violet color. It really ought to be charged by now, but gives no indication that it is so...unless it came fully charged and the violet color is the full-charge indicator, which I doubt, most batteries ship at around 40% for sake of handling under various temperature conditions.

I have the same set. The charger is slow, but the colored bar will eventually turn from purple to blue. For a full charge from dead, mine takes about 5 hours.

On the plus side, I perceive that a battery charged on the charger is topped off better than one charged inside the phone. Ones from the charger seem to stay at 100% for close to an hour before they start to show discharge, versus the internally charged battery, which shows discharge immediately.

I bought the 12$ charger and 2 batteries that were labeled for evo. They got here pretty quickly and work perfectly!

before you posted this, i went ahead and popped the new battery into the phone, it hadn't turned blue by that point. I put the stock battery into the charger when it was at around 70% and after over an hour its still violet.

So, couple inquiries:

Lets say I did not let the new battery charge to full after taking it out of the external charger, can that capacity be regained.

The tiny little informational that came with the battery says it needs to do 2-3 full charge/discharge cycles before it reaches promised capacity. Did anyone try this, and how did you do it? I went ahead and turned on all system toggles (wifi, bluetooth, 4G) to kill the battery. Since I'm trying to gain battery life this is a bit weird, and also I thought lithium ion batteries don't need to do this. But it was a cheap investment as long as it doesn't explode and make me a eunuch.

LI-Ion cells do not need to go thru cycles. thats probably old NI-MH or Ni-Cd instructions.

if you take the battery out of the charger its the same as unplugging your handset from the charger if the battery is not fully charged. you will not lose any battery health.

if you cycle the lithium ions down to near full discharge that is what kills their capacity....that and heat so top the cells off when you are able to.

i have this battery package and i use these more so than the OEM htc battery. the charger will turn blue. i remember when i charged up the ones i have it took a while to do so...

these cells will NOT explode if you follow the directions on how to handle lithium cells. just because they cost 12 bux do not make them more susceptible to explosion than batteries that cost 60 bux..
