someone help. Dead hybrid battery

I recently bought a used Toyota Prius. NHW11 model. There are relatively few prius in my country kenya. (Rough estimate fewer than 20). 90% of the cars in kenya are used cars from japan. I bought mine over the internet and had been used for 7 years with a milage of about 34000. However, when i tried to start it, it couldnt. There are no dealerships of the Prius in kenya so i took it to the only qualified technician in the port of Mombasa. After several days, he managed to recharge the battery, and i managed to drive the 500 kms to the capital city, Nairobi. I had barely reached Nairobi when it broke down (problem with gearbox) This was sorted out in a week. However the Ni-Mh battery has completely discharged. I tried the only technician in Nairobi, but he passed the verdict that the battery is dead and it needs replacing.

Its been 2 months now and i have not managed to get a used/new replacement battery in Africa. For us here in kenya, a car is a major investment and i had used all my savings to purchase the car.
can someone please tell me where i can buy the NHW11 battery(year 2000)? A purchase online would be ideal as i dont think that the battery could be found around 1000kms from where i live

 

I really appreciate the feedback am getting from you guys. The link from saminjax was really helpful as i have contacted the ebay guy and try to negotiate on the price.
To answer the Dutchman, here in kenya, you buy cars via the internet as you end up saving between $1000 to $3000 on a $5000 vehicle. An example is that i bought the prius from japan at $4600 (inclusive $1100 Shipping to kenya). The price here is about $13000 (After you include duty and handling) so i ended up saving about $4000 importing via the internet from japan. The downside is now when you get a "lemon" like saminjax calls it.
We are also trying to promote the use of "greener" cars in africa, though toyota has refused to introduce the prius in our country as yet. so all the prius here in kenya are direct imports from japan.

The technician here has really done a great job trying to resuscate the battery, but unfortunately the battery does not store power as its supposed to and the voltage goes to unacceptable levels every time we try to start the car. Everything else was checked and the problem zeroed in on the battery pack. The only option left would be to purchase a new/used but workin battery or sell the car parts as salvage. the latter option wouldnt work as the number of prius here is very small.(less than 20 in the whole country).
I am still counting on your support to try and get a good but affordable battery pack. so if anyone out there has an idea of where to buy it from, i will really appreciate and this will go a long way in convincing other users in Africa to buy the prius if they can be assured the availability of important parts like the battery
