I have a 1100 mhA Nicad 4 cell Rx pack that was bought and cycled about 15 months ago. After a full charge and discharging at C\5 (.22A) and a 1v/cell cutoff, it showed a capacity of 1,048. I just cycled it again today and it read 974. This is about 7% drop. First - is it normal for the battery to come in under its rated capacity on initial cycle ? And second, is this 7% drop acceptable and normal for this age battery ? I use an Ace Digipulse charger to charge all my batteries. Its about a 15 hour charge , then I discharge on a Rip Max charger/discharger.
Thanks in advance for your help ............
