There are some contrasts between the differing performance expectations and resource environments of two categories of stationary battery system users. It proposes some simple requirements for battery monitoring at cost-constrained sites with modest-sized stationary battery systems and proposes a solution to providing battery health assessment at such sites.

Operators of high-profile, mission-critical systems spending large sums on batteries and power electronics justifiably want assurance that their standby batteries will perform per specification. Many of these high-budget users employ sophisticated battery health assessment equipment that gives early warning of degradation in one or more battery cells and notifies the user so he can take appropriate action.
