Reconditioning NiMh & Alkaline

Thus far, its a slow process but:

1. a 100ah 1.2v Nimh battery (14 years old) takes about 8ah and over the past 3 days is steadily showing improvement (tiny). It discharges 120ma @1amp. This is...

Which coil yielded better results

Hi Tyson,
In you initial posts you mentioned you made the Alexkor circuit coil with more turns than shown in his original circuit. Did your coil yield better results ?
