Hi guys, I need to buy a new battery for my Samsung galaxy GT-I9000, because the one I currently have doesn't hold charge for that long. I wonder, do you think it is safe to get one off ebay/amazon, or is it better to get a samsung's?
thanks

A short, practical addendum that ties together the points raised by , and other replies — two clear takeaways: modern charging practice, and what to do about a swollen cell.

Modern first‑charge: the old “leave it on 15–16 hours” rule comes from nickel‑based batteries and does not apply to lithium‑ion phone cells. New Li‑ion packs ship partially charged and are ready to use; a normal charge to full with the phone’s supplied (or properly rated) charger is enough. Habit tips that materially help longevity: avoid repeated full discharges, keep the phone out of high heat, and avoid leaving batteries at 100% in hot conditions when possible. Battery University — How to prolong lithium batteries. (batteryuniversity.com)

Swollen battery = damaged cell and a safety risk. Bulging usually means internal gas buildup; continued use, charging, puncture or crushing can trigger thermal runaway (fire). If the cell is removable (the GT‑I9000’s battery is removable), power the phone off, remove the battery carefully without prying the pouch, place it on a non‑flammable surface (sand/kitty litter or in its own plastic bag), and arrange proper disposal. If the battery is not user‑removable, power off and contact an authorized service centre — do not try to force the case open. Do not puncture, compress or put swollen batteries in regular trash. [Android Central: why batteries swell] (https://www.androidcentral.com/phones/tech-talk-why-do-batteries-swell). EPA guidance on lithium‑ion disposal and safety. (androidcentral.com)

Practical disposal and next steps: many areas offer battery collection programs (Call2Recycle in the U.S., municipal HHW or electronics recyclers elsewhere). Before transport, tape exposed terminals or bag the cell and tell the recycler it is swollen/damaged. If the OEM replacement just bought is new, put it in service normally; retire the old swollen cell immediately and recycle it safely. Call2Recycle: battery recycling & safety tips.

Check with a site like buy.com (now rakuten.com). I got batteries for my Android phone from them some time ago (2 extras) that are OEM units (same manufacturer, just not branded for the phone) with the same power ratings, at a fraction of the manufacturer's price. Absolutely zero problems: www.rakuten.com - I have been purchasing most of my computer and electronics cruft from them for almost 10 years now, and they have always been responsive in dealing with DOA's and other problems.

FWIW, here is a link to an OEM Samsung battery for the GT-i9000 - all of $12USD, including free shipping! :-)

Ebay and Amazon is completely safe, I buy the OEM batteries and the aftermarket batteries everyday, and Ihhave sold hundreds, I use them myself as does my wife and whole family, no need to spend $70.00 for a battery when you can get the same thing for 10.00 please don't waist your money,

Just a reminder, if you buy aftermarket and your device has NFC, the NFC will not work, because the OEM batteries have a NFC chip in them, just FYI....

Thanks. , I had a look at the site you mentioned but do they deliver also abroad? I am based in Europe and the site seems to be dealing only with US.

: how do I know if my device has NFC?
thanks

I think ebay is better.

just wanted to add that I eventually bought the OEM battery. It was sold to me as new, so I was wondering how long should I leave it in charge for? The old usual 15-16 hrs? ALso, since I am on the subject, I have noticed something with the old battery...i notice it is swollen, not like a balloon, but I can see that the shape has slightly changed. The thing is the battery came with the phone when it was bought about 2 years ago, so it can't be due to a dodgy battery bought somewhere. What should I do, can I keep use it or is it a very bad sign?
cheers
