Primary batteries and primary battery packs
A primary battery pack is an ideal solution when energy is needed intermittently, over a long period of time.
The advantage of primary batteries (lithium- primary or alkaline-primary) over secondary batteries is the higher energy density in regard to weight and volume. Although there is no maintenance of primary battery packs they have a long lifetime. Thus, this type of battery is optimal as use as a back-up battery.
Other advantages of primary battery packs are:
- Low temperature compatible
- high discharge currents
- long storage periods at any charge states
