Thanks, Everybody for all your help I am going to be busy. Does anybody know if the individual cells can be bought new? MK

I have replaced some of the cells, two on one occasion and one on another. Both times it kept the car going for a few months and then another cell would die. I suppose that if I replace one (or a small number of) cells now, then it will again keep the car going temporarily, until another cell dies. The ideal solution is to replace all. On balancing, I measured the voltage of all the cells the last time that I had the pack out of the car, and I used a headlight bulb and wire to take energy out of the ones at the highest voltages. The problem I see though is that each "cell" that we are talking about is actually 6 individual NiMh cells in series, and those cells inside can be imbalanced too. And there is nothing I can do about that. Attached is an image of a replacement cell from ebay.@toffee_pie I couldn't find this cell type on that website (though very similar ones are there) Any further suggestions are much appreciated.

Thanks John I will look into that,

Hi luck, Thanks for the info. The Lexus Garage want €4600.00 to replace my battery but all I need is the cells. I thought it would be much cheaper to just replace the cells but I can't locate them new. All the best, Malcolm.

Hi, I have a 2006 Lexus GS 450h and the hybrid battery had to have cells replaced three times in the last year. The garage that did the work said I need a new Hybrid Battery as the car is so old.buying a new battery is very expensive. I love my car and it still looks and drives like new. My question is can one buy NEW cells for the Hybrid Battery and replace them all. Replacing a bad cell with a second hand cell is only a temporary fix for a 06 car.
