Battery for laptop acer aspire 7741g 454g75mn

I changed my battery 11 months ago, and in the last few days, it suddenly only has 20 minutes of battery life. I contacted customer service, and they sent me a new battery. I hope this one will last longer. Their response was very quick and efficient.

Hello
This is my second purchase on this site because the search function is very easy and the products are very well described, and also, and most importantly, because I'm very happy with my first purchase—a quality battery.
I highly recommend this site.
