What size resistors do I need to do a load test with AAA,AA,D size batteries?
I use an "All-Sun BT21 LCD Display Digital Battery Tester about 20-120mA Digital Battery Instrument" it has 3 load settings, you can buy them for around $12, slightly to small to test an 18650 but i have heard it can be modded.
Do you know how accurate they are? Have you tried it against a DMM reading?
A DMM does not load a battery while testing, Also you cannot disable the load on this battery tester, So i cannot compare like for like.
My DMM shows an Eneloop AA at 1.3305v
The battery tester with low load = 1.33v
med load = 1.33v
high load = 1.31v
