I got this laptop battery along with my laptop, Forsa 3303. The battery type as written on the bar code is FS-0002459. It’s a lithium ion battery and made in China (which quite surprises me because my laptop is not made in China, I think). The warning section is written in English, Spanish, and Chinese. The battery is bar-type, and to place it on the laptop is quite easy: slide the battery lock on the laptop, plug the battery on its place (pay attention to the matching hole for the plug), and there it goes… You can use laptop with the battery on now. To charge it is very easy too: connect the laptop to electricity (make sure the laptop is turned off), and it will charge. The charging duration will take about less than two hours if it’s completely no power in it, but I usually charge it for less than one hour or one hour at the maximum because I couldn’t let the power to be completely empty (I can’t wait ‘til it loses power completely). The full power will hold for about, I don’t know, well, probably about eight hours or so. I can’t tell for sure because I rarely use the battery (I use electricity most times). But I always carry this battery along when I carry my laptop. I use it in emergency (when the electricity went off), and that’s why, it’s very important to keep the battery full-powered when I want to use it. I always remove the battery when not in use, and that way the battery’s power won’t be wasted. I feel satisfied with the work of this battery and it never let me down. It’s always there whenever I need it.
