Sanyo NCR 20700B // 20700 4000mAh 15A
"Sanyo 20700B 4000mAh 20700 Bench Test Results...a peek at the future?
This Sanyo is one of the new generation of slightly larger cylindrical cells being brought to the market primarily for automotive use. It is 20mm in diameter and 70mm long, a 20700 battery. Other sizes and designations for similar cells from other manufacturers include 20650 and 21-70.
I am rating this cell at 15A 4000mAh. It runs a few degrees hotter than the HG2 but at 10A and 20A continuous down to 3.2V the Sanyo lasts about 25% longer."
