Are replacement batterys good quality?

I took a chance and bought the Chinese knockoff batteries. Here's a post about my experience.

This space is probably more appropriate than my original post.



I bought a "1600mAh Battery" from a Chinese seller for my Desire HD. After testing alongside my 2nd DHD (yes, I have two!), it had nearly exactly the same power output - in fact slightly less - while playing a HD video down to 10% power (HTC battery was at 16% after the same time, max brightness, nothing else running, standard OS). I put the 'slightly less' down to it being charged less times, so effectively it's the same as a 1230 standard HTC battery.

I sent the following to the seller:

This is the response I received:

There was no suggestion that maybe I'd received a faulty item - apparently the seller knows his goods are fake. Unfortunately a negative rating won't do much at 40k sales. So I just put in a complaint.

So yeah - I wouldn't be buying a replacement battery anytime soon - a portable charger might work, but that's nearly like carrying a second phone in your pocket. What I DO find is that battery consumption after the first few days of 'oooh-I-got-a-super-duper-new-phone' is generally fine enough to last at least a day. I get 10+ hours of non-stop music from my phone while at work ... obviously it'll always depend on your usage but keeping a charge-cable at work, in your car, and at home, and just whacking charge every time you think you might need it...

i've purchased the 1800mah andida battery for $10 and it lasts me for the whole day. i couldnt compare it to the original battery though as i have bought all the stuff i needed first extended battery and otterbox case so i havent used the original battery b4. so just to let every one know i unplug my phone at 6.30 (when i wake up) and charge it up at around 10 in the night. During the day i'll check my emails, facebook, 15min-ish or more on game dev story and some web browsing. So to me i think some are.
