FDK Twicell 2500mAh 4-AA Cell 4.8V NIMH RX Square Pack

FDK (formerly Sanyo) HR-3U-GTX AA 2500mAh NIMH. "Twicell" low self discharge type (formerly known as Eneloop) which comes partially charged and is the same product as prior Eneloop cells. Same size as 700 and 1100 NiCad pack above. Less weight than 1400 NiCads above. Good cell where fast charging is not a needed but extra capacity is desirable.

All AA size cells over 1700mah should not be fast charged ever! If you repeat this experiment, your on your own. I recommend only factory wall wart charging with units rated of 70mah or less for these type cells.
