More on the earlier PSA:

Sterlingtek.com, Las Cruces New Mexico: Canon BP511-“equivalent” battery, for values of “equivalent” meaning 2000mAH vs. original 1100mAH. $11.99 vs. $90 for OEM battery. Fits, uh, about fifty different Canon cameras including the Powershot Pro90 IS. Ordered Friday with USPS first-class shipping, received today. Two thumbs UP.

Laikeet.com, domain registered in Pennsylvania, ostensibly based in Bradenton Florida: Nokia BLC-2 battery, $2.99, fits about 18 different Nokia phones including the Nokia 6010. OEM-equivalent 875mAH. Ordered Thursday with allegedly USPS flat-rate shipping. Will probably receive it sometime this month... you already know my opinion of these wankers.

I'm probably going to have to go ahead and order another phone battery, because I need a working phone this week, not three weeks from now. So my laikeet.com order is a total loss.

Without testing them I would never know what crap is in them. Radio Shack should be a reputable company yet their Motorola knockoff batteries would trip the safety circuit on my equipment, have no capacity left or if new in the package do either of those or fail after over night charge discharge testing. I'd get various brands in with phones and run tests on them for my amusement. In every case they would either have lower than listed capacity, no capacity or trip the safety system at some point.

I've never seen anything like what they have. It's recovered 'dead' batteries and brought limping ones back to full capacity. They had adapters for Lead acid liquid and gel, Ni-cad, NiMH, Lion from rechargeable hearing aid batteries to forklifts.

Lithium ion battery packs should have a sophisticated controller which monitors voltage, current and temperature. The safer ones that last the longest have a separate circuit for every cell that load balances them to prevent damage but I've not heard of those in smaller consumer gadgets.

glad you like sterlingtek :)

my last order was for a BP511 for my canon camera, as well as 3 other NB2Ls for my older camera. total cost is less than OEM for a single unit of any of those. love it.

Well, not a TOTAL loss - after all, if it works you'll still have a fairly cheap backup battery.
