and then take the leads off the old battery and the little yellow whatever it is on the other end off (use a needle nose to take it off the weld points and be careful to keep it in tact)... It's easy to do... The thing is on the end without the leads you have to cut the connection to the two battery's and use the spring battery connector and solder to the little yellow thing that controls the voltage I think... Use regular Nimh AA size battery's...of course you need to save the little temperature sensor that is on the white leads and use this on the new set... as shown in the pic.
Here is the result:
Hope this helps Emate 300 battery needs out there! Sorry I could get more descriptive but just don't have the time at the moment...
