BLESYS BPS35A SVF152C29M SVF142C29M Laptop Battery for Sony Vaio SVF152A29M SVF15221R6E SVF1521A2E SVF153B1YM Notebooks 14.8V 2200mAh 33Wh

I am not sure how long a battery should last, but i need do presentations that can last 2 hours and there is not always a power supply available, my original battery lasted quite well but this the second replacement one i have been sent and realistically i only get about 40mins out of it.The company i bought it from have been very good in sending me a second one but even following their instructions to the letter, it still does not fill my needs, but hey i may be expecting too much from this battery

On receipt the battery would only fully charge to 80%. I was willing to put up with this ,as it was better than the original not charging. A few weeks later this issue became "No battery is detected". I was happy with the price and i'm not sure how many other options i have. I was going to rebut from here but there seems to be other negative reviews. Buy with caution.

I use this for my laptop

Very easy to order, quick delivery, easy to install and what else can I say? It does what it says on the tin.Recommended.

Only work for two day. Don’t buy.
