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.

RC Receiver Battery Packs
Before the switch to lithium chemistry, NiCad packs powered the receiver and servos on countless models, and they remain a familiar option for onboard power. This category collects receiver NiCad battery packs in the cell counts and shapes used to fit them into an airframe.
Voltages and Layouts
The packs cover 4.8V four-cell and 6V five-cell arrangements to match common receiver and servo needs. Shapes include flat, square, and hump or nested block layouts, so a pack can be fitted into the space a given fuselage allows.
Cells and Capacities
Radical RC assembles packs using AA-size cells, including 700mah and 1100mah options, alongside FDK and Sanyo cell packs in similar sizes. Matching capacity to a model helps balance flight time against weight. As with any older pack, a careful charge and a check before flight are good practice.
Compare the receiver packs below to find the voltage, capacity, and shape your model needs.
