Sony Ericsson BST-37 K750i Battery

Remarkably cheap, but it works perfectly and has brought new life to trusty and much used Sony K750i. Highly recommended.

I purchased the batery in question and did not have the Sony-ericsson logo. It took a few hours to fully charge but seems to be working fine now and phone does not run out of power as before. I wouldn't know if the batery id old stock but so far has been an inexpensive experiment and worked for my phone.

Very good price, it arrived quickly, fitted perfectly, does what it says on the tin. As far as I'm concerned Amazon, and there suppliers put some of the high street shops to shame.

I had problems with my mobile phone not fully charging so I ordered a new battery and also a new charger. Both arrived very quickly and both are fine. Excellent value for money and not as expensive as I thought they would be. It's as simple as that.

bought this as old battery didnt last long any more read reviews of others getting bad batteries not holding charge mine came in plastic packaging had to cut it out of it few hours to charge first time use went to 100 % on phone looks like i have a good one not on charge looking through menu an after 30 mins still at high 90s plus strong signal old battery signal usually weak time will tell if it remains decent

As said by a previous reviewer, the battery is very old stock. I found the product to be of very poor quality as it will not hold a charge. I think Amazon should pay more attention to the quality of items supplied by third parties as this reflects on Amazon rather than them has only made me wary of purchasing from Amazon in future.

Bought as a replacement battery for my wife's mobile to check out its failing performance on the old battery. The battery provided worked for a while and rejuvenated the mobile however after a week the phone stopped working totally so after reading other reports not sure if this was due to a poor battery or a failed mobile. Also as with other reports battery was old stock showing 08/17. Since the battery was cheap it served its purpose of checking out the phone but not good value.

I noted the previous comments about alleged ages of the batteries supplied. I can only speak as I find and that is to say my 2 batteries arrived in good time, hold their charge well and haven't let me down. For the money they were a bargain.

Un peu plus chère qu'une batterie "démarquée" mais tient très bien la charge. C'est parfait!

Le Produit est conforme à l'original et neuf (acheté chez euroaccess). Elle tient correctement la charge 8 jours durant avec une faible utilisation (sur un w810i).

Für den Preis von ca. 5 € ist der Akku ganz ok. Allerdings sollte man nicht zuviel erwarten. Er hält ohne großartige Betätigung des Handys ca. 3-4 Tage, also kürzer als der ursprünglich dem Sony Ericsson beiliegende Original-Akku und ist meines Erachtens somit qualitativ schlechter. Der angebene Ursprungspreis von knapp 50 € ist utopisch und fern jeder Realität. Insoweit es sich tatsächlich um ein Original-Produkt von Sony handelt, sollten diese zuschauen, dass sie ihren Namen nicht für minderwertige Produkte hergeben und wie in der Vergangenheit hochwertige Geräte und Komponenten liefern.

Le batteries de ce type ne tiennent pas la charge très longtemps. Je pensais que ma précédente batterie était très fatiguée, mais je m'aperçois que la nouvelle ne tient pas beaucoup plus.

Der alte Akku meines W810i ist nach maximal 1 Tag leer gewesen, nach 6 Jahren kann das schonmal vorkommen, zumindest wenn ein originaler Ersatzakku für so wenig Geld zu haben ist! :-) Akku hält wieder 1 Woche und länger, je nachdem was man mit dem Handy macht. Es gibt zwar nurnoch wenige Leute die sich diesen Akku kaufen aber er ist unschlagbar günstig und orignal von Sony Ercisson.
