Battery Deal: Genuine Dell Battery Inspiron 13R N7010 N5010 N4010 9T48V M511R GK2X6 | eBay

I ordered one of these “Genuine Dell Battery Inspiron 13R N7010 N5010 N4010 9T48V M511R GK2X6” from eBay seller for $17.99 and free shipping. Its a 9 cell, 90Wh pack, which, I estimate, probably has 2,800 mAh cells. It arrived quickly and was packed well, but I haven’t opened it yet.

Works out to be $2/cell and $0.19/Wh, which is a pretty good deal.

There are a couple of downsides though. The pack I got had ~40 cycles on it. Not bad, but probably 10% of the lifespan. It wasn’t a surprise either, since the pack wasn’t described as new, it was listed as manufacturer refurbished.

Which brings me to the second problem. Before purchasing, I asked the seller for more information about what “manufacturer refurbished” meant and they didn’t reply. After purchasing and receiving the pack, and checking the cycle count, I decided that it would be worthwhile to get another couple of packs if I could get them at a lower price, so I took advantage of the “Make Offer” featured on the listing and offered a lower, but still reasonable price for two. They ignored the offer and let it expire.
