Sony BA900 1700 mAh Battery for Xperia Series

Ordered a battery but later discovered that it was a fault with the 'phone. Therefore had to return the battery. This raised a few issues but they were handled well and to my satisfaction. would use again.

I purchased this replacement battery on behalf of my mate, as he has no computer or laptop and no idea about the web. So when it arrived at his house, he told me that he received a parcel and became cautious until I told him to open and see what was inside. Now every time he wants sometime from the shops, he asks me if I can order through the website. It makes his day, when items arrive much cheaper and of great quality prices.

got the right size now and fits perfect

Arrived on time seems to be as expected

Very apprehensive in ordering after reading so many negative reviews.No complaints up to now, does what it says on the tin and does also seem to be a genuine Sony battery, even though it came in their own packaging.Service and delivery excellent............Time will tell.

Works very well; good value for money

does what it is supposed to do , good buy

Don't buy this battery... It is not a genuine Sony BA900 1700 mAh as specified. I purchased one of these as a back-up battery for my Xperia Mobile Telephone and only after 2 charges, it has failed. Just won't charge at all. Contacted seller about the problem and they said they could not help me. Just a waste of money...! Go find a shop that sell genuine mobile phone battery's, not third-party online companies!!!

Good value product. Pity about the packaging!

The product sold by amazon.co.uk was original and lived up to my expectation. It charges reasonably (not fast) and the continues for a whole day with reasonable data usage and calls.

Pretty terrible really, and unexpected given all the good reviews. The battery never drops below 50% before my phone completely switches off. I have to recharge too frequently, since I can only use half of the potential power. Disappointing.

Took just 1 day to arrive and was very pleased as my other was very poorly. It done the job for my phone so will use the sellers again.

Charged it up and use it all the time. Great on days out when the battery in use runs out at a crucial moment!! Very good!! Very happy!!

Yes it was perfect,phone is up and running once more.

Ridiculous. The battery I received is clearly not a Sony original battery. It's some knock-off (the silver sticker looks nothing like the one that came with the phone, and the text on the battery is in different places). I'll see how it holds up, but I don't expect much.Also, when I bought this battery there was something like 50+ reviews. Now they have all disappeared?
