Laptop batteries from ebay

[DarrenSV650S]

The battery in my acer is dead. There are some Hong Kong ones on ebay for £20 that have a 5200mAh rating compared to the standard 4000mAh.

Just worried how long it will last. Has anyone bought a cheap laptop battery from ebay?

I think it falls down to luck, I have know people to get cheap batteries and chargers from ebay for their laptop and they have been as good as the standard ones (if not better)

Yet I have know people that get them and they are utter crap

I got one from ebay for an acer aspire 5103. It didn't have the hologram for some reason (I can't remember why but there was a reasonable excuse). idn't hold its charge as long as I hoped but it was OK. Is a bit of a lucky dip though, not sure I'd do it again
