Charger presumed to be factory wall charger. Peak chargers are poor choice for forming, you'll struggle. Peak charging is only reliable after proper form charging. Form charging when new is a MUST. Repeat form after 30 days or more storage or after any replacement of cells in pack. Most packs will reach the good zone (85% of rating or better) within 3 to 5 cycles. They continue to improve slowly over further cycles. We have seen some cells require 10-15 cycles to hit full stride. You do not have an issue if you formed the pack properly and it's continuing to improve (no mater how slowly) over a number of cycles. Simply keep cycling it. We only want to hear about it if you have formed it properly, have at least 6 cycles of data "recorded on paper" and the results are staying flat or reducing. Your data sheet is required with the pack upon return. All other packs will be returned to you.
There is no warranty, return or telephone consultation available if you failed to form charge your pack as described above. Learn from your errors and order a replacement. I've been though this hundreds of times, the proper and reliable methods are established. Anything outside of these proper methods is experimentation at your expense.
FDK (formerly Sanyo) AA 2500 NIMH. "Twicell" Low Self Discharge (LSD) type (formerly known as Eneloop) which comes partially charged and is the same product as prior Twicell (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.
6V Weight 194g, 6.875 oz.
Individual Cell Internal Impedance 20.0mΩ
All AA size cells over 1700mah should not be fast charged ever! If you repeat this experiment, you're on your own. I recommend only factory wall wart charging with units rated of 70mah or less for these type cells. Cell color may be white or dark green.

FDK's new more environmentally friendly NiMH battery. Although these are advertised as charged and ready to go right out of the package, we recommend a forming charge period prior to use. The Twicell NiMH type has lower daily self discharge than typical NiMH cells. These cells have done well in our in house tests and I feel good about offering them for RC usage.
Be aware this cell is a newer product and does not have a deep record in the RC community. However, thus far they seem to be performing well. We offer them for your evaluation.
Overnight charging suggestion is stock factory wall wart 50mah or less.
Although FDK's website shows Cx1 (capacity x 1) fast charge rates with a NiMH rated charger, I'm not prepared to warranty any packs damaged by fast charging or peak charging in any form. If you insist on experimenting with fast charging and damage a pack, call FDK, not Radical RC.
