Review on Battery 357F9 for Dell Inspiron 15 7000 / 7559 / 7566 / 7567 / 7559 / 7566 / 7759 / 7557 (0GFJ6, 71JF4) 11.4V 6400mAh by Wiktor wikliski ᠌

In general, this is already my second battery for Dell, I bought the previous one for 3.5k marked "original". Well, that battery from the very beginning kept about nothing, although then (due to the long use of the laptop only from the outlet) I thought that a couple of hours at max. energy saving is the norm, then it swelled up after 3-4 months. But this battery made me remember what really great battery life means (within 5-8 hours) keeps working in intellijidea, surfing the Internet (the main thing is not to load tabs with any js eating garbage) and working in word, which is quite a lot :) I hope this battery lasts longer.
