Rcvr NiMhs fast charge is 1amp, slow charge is 0.5amp. These type cells either 2/3a or AAs tend to overheat/cook and can be damaged at higher charge rates.

Glow plug igniter batts - mine are all NiCd and I use 0.5amp as a fast charge and 0.2amp as a slow charge. Slow charge is what the rate the wall type plugin charger that came with the igniter delivers.
