Welcome to a laptop battery specialist of the IBM Laptop Battery
Technology moves so fast that eBay has turned into a scrapyard for servers and other hardware that are often in great working condition.
Check out the IBM System X3655, for example, which costs £246 and comes with 720 free Nectar points worth £3.60. This server in its heyday would have easily cost 20 times more than that.
It comes with two dual-core AMD Opteron 2216 clocked at 2.4GHz (the first five purchasers will get a free upgrade to the Opteron 2218 which is clocked at 2.6GHz), 32GB DDR2 667MHz ECC RAM, an IBM ServeRAID 8K RAID controller with battery such as IBM ThinkPad T42 Battery

backup and 256MB cache, eight 2.5in SAS or SATA hard drive bays, two redundant 835W PSUs, a DVD drive and two GbE ports.
The X3655 can actually ramp all the way to 64GB and has 16 DIMM Slots. Expansion slots include two PCI-e x8 and one PCI-e x4 low profile ones, six USB 2.0 ports, two PS2 ones, two VGA ones and one Serial one.
The server comes from an ex-corporate environment and would be ideal for a startup, small business or individual looking for a test system to try some heavy-duty applications like VMWare EX64i.
Although these new batteries have lower voltage and lower capacity, they would be safer and have higher energy density than conventional lithium-ion batteries.
Considering that lithium-air batteries can store up to the impressive 11,140 Wh/kg, while being light in weight, no wonder big company like IBM are amongst the providers of these items.
A prototype of a battery running on the proposed anode for powering electric vehicles would be safe, affordable and light, and therefore would provide higher performance, higher efficiency and longer driving range. Such invention definitely has the potential to stimulate more and more people to finally make that step and forget about their diesel vehicles.
