Qty per pack
The number of individual batteries supplied in the kit.
Buying a multi-cell kit is convenient when you need more than one battery, but it is especially justified when you need several batteries for one device. In such cases, it is desirable that these cells are identical in characteristics and condition (it is not recommended to use fresh batteries in conjunction with discharged ones); Batteries from one set usually satisfy these requirements.
Charge cycles
The number of charge cycles that the battery can withstand without noticeable deterioration in performance.
The charge cycle refers to the period of time from one complete discharge of the battery to another, when the battery is first fully charged and then discharged to zero. In practice, this method of operation is relatively rare - much more often the batteries are charged under-discharged, and sometimes the process has to be stopped before the charge is replenished to 100%. In addition, the number of charge cycles is usually indicated for ideal operating conditions: a “native” charger, a relatively low load during operation, compliance of the ambient temperature with operating parameters, etc. Therefore, the number of cycles indicated in the specifications is quite approximate, and in practice it is unlikely that you should expect a 100% exact match. Nevertheless, by this parameter it is quite possible to evaluate the durability of the battery and compare it with analogues.
