I'm replacing batteries on a hair clipper following this tutorial. New batteries have higher capacity than the original ones :
- old batteries : 2x BYD AAA NiMH 1.2V 600 mAh
- new batteries : 2x Eneloop AAA NiMH 1.2V 800 mAh (5th gen, BK-4MCDE)
My questions is : What is the impact of this capacity difference on the charging time ?
The clipper manual is not clear about the charging time of the original batteries :
To obtain and maintain the longest battery autonomy possible, allow it to charge for 16 hours before using it for the first time and then approximately every three months.
And 16 hours seems to be a very long charging time for these small cells.
AC/DC power adapter
MODEL NO : HKA-024100EC-230 PRI. : 230V~50Hz 40mA SEC. : 2.4V DC 1000mA 2.4VA
Despite what is written on the adapter, I measured 4.5V on the output jack using a cheap multimeter, not 2.4V. I don't know if this measurement is relevant however.
