SONYERICSSON Standard battery, BST-25. 770 mAh Lithium polymer battery for the T606, T608, T610, T616 phones. Retail packaged.

I bought this replacement battery over a year ago and I only use the phone T616 as an alarm clock but it's been doing a great job of that for going on ten years. The original battery still worked but it was starting to bulge. I keep it on the charger 24x7 and rarely take it off. This battery is performing exactly as a brand new battery should. I'm very pleased with my purchase and so grateful that someone is still selling the original batteries for it.

Battery arrived quick, but the blister pack was unsealed and the battery was uncharged and unchargeable.I left a poor vendor review before I bothered to try to contact the company. Dopey.MobileCity got in touch with me and sorted everything out very quickly. I've no reason to think it would have been any different if I called them before rating them.Sadly, it seem I can edit this product review, but not change the star rating. Go figure. I'd be happier if Amazon would just delete my comment.

This one took a charge and is working fine.

Battery arrived quickly and has performed very well, as expected.

Phone did not come on at all after using this battery

Back up batteries for my aged Sony/Ericcson T-610 cel phone. THANKS!

This battery is performing very well.

Good battery working as expected
