Defy+ 3500 mAh battery opinion

[TheBirdOfHermes]

I've been looking around eBay and I came across the 3500 mAh battery for the Defy+.
Has anyone tried this, and if so, what are your opinions? 3500 mAh is a massive force of battery life, even though I am sure the parts are not that quality from looking at the 8~10$ average eBay price.
So should I get this battery to serve me as an extra/backup one?

It will be actually much much lower mah then its mentioned for 8$ believe me.

I understood that.
Anyway, where I can buy another decent battery for backup? ^^ I love my Defy+ and I'm going to stick to it for a while, better get myself another battery.

I have one. Not sure about the total mAH but the battery seems at least better than my old stock battery. No one makes a good case for a Defy with the extended battery. I've resorted to running the phone naked. I might get some gaffers tape to add some protection.

Also keep in mind your water resistance goes away with the extended battery. Not a big deal if you are careful. The bigger battery combined with a battery saver to turn off data/wifi when screen is off allows the battery to easily last more than a day.

Edit: I changed back to my old OEM battery. The extra bulk made the phone too annoying to carry. There was extra battery life but the meter did not reflect the upgrade so it was hard to gauge. It's annoying to be running at 0-1% for a few hours because it could die anytime.
