Thanks for that post, I am glad you have got your's working - I am still having problems but I have got to the bottom of it - one of the so-called new cells was in fact failed open circuit. Disappointing - I paid over 4 dollars per cell plus postage from the USA to Europe!! I also had great difficulty squeezing tha batteries into the original box and this caused numerous problems which masked the real thing, as I had to take the battery apart several times. So, a warning to all battery builders - it's a tough call. Guess I shall re-order more cells now.....
