Mixed feelings with the battery

The battery is of size before a monster that should be clear to everyone who buys this battery. Also has gone off on the battery cover after a relatively short time the paint.
Now to more subjective impressions. I can tell how bad this assessment is objectively, but after half a year of alternating use with the original battery I am again completely switched to the original part, because I no longer had the feeling to have significant battery gains. And by the significant weight gain, not to mention the ugliness of this lump, I decided against the continued use.
No real recommendation from me ....
