Background
Got this battery analyzer for BA-5590 family batteries and/or 18650 Li-Ion cells and/or packs, like used in the BB-2590 family of batteries.
Description
This is a more sophisticated battery test instrument than the military type battery chargers. It's made mainly for maintaining commercial portable batteries but there is an adapter for the BA-5590 style battery.
This is a 2-bay instrument and the C7400 is a 4-bay version. Has charge alogrithims for SLA, Li-Ion, Ni-Cad and Ni-MH. Does not have SMBus capability.
For testing one BA-5590 family battery 2-bays are required so the C7200 can only test one BA-5590 family battery at a time.
The latest (March 13, 2007) firmware is 6.12. [Note the C7200 & C7400 C-Series testers that also do Li-FePO4 batteries]
Internal Programs
Basic
Auto - exercises - recondition if needed
Charge - fast charge w/o capacity
Prime - charge-discharge until max capacity
Quick Test - State of Health for known battery types (requires Learn)
Advanced
Self-Discharge - 24 hour test
Life-Cycle (destructive)
Dishcarge Only - % of capacity
Extended Prime - start with 16 hour trickle charge
Ohm Test - 15 seconds DC based
Run Time - based on cycle of standby, Rx and Tx currents (needs to be programed)
Boost - for use with protection circuits or open or shorted batteries to rejuivinate them
Learn - takes from 4 to 8 hours, builds info needed for Quick Test, involves multiple charge/discharge cycles
Quick Learn - involves a single charge discharge cycle
Custom 1, 2, 3 & 4 - up to 5 cycles with IF test branching
Battery Adapters
Cadex makes a plethora of adapters that are specific to some commercial portable battery. In addition they make some universal probe type adapters and a cable adapter p/n 07-110-0115 that has wires for positive and negative as well as a temperature sensor.
Cadex makes many battery adapters for their battery analyzers. I expect that the difference between the following battery adapter relates to the extra top contacts.

Philips M3538A Adapters
This C7200 charger was used by Philips Medical to test their HeartStart defibrillator Li-Ion M3538A battery.
Ericsson Prism Adapter 7-4282
Got this as a donor unit to make my own adapter. Chosen by low price on eBay.
Fig 1 Ericsson Prism Adapter 7-4282
Fig 2 The tray at left and rear cover just to it's right
are common Cadex adapter parts as is the plate and
PCB on the right. The gray block is a custom part
the the cutout and mounting holes in the plate at
the right are custom.
PCB appears identical to M3538A Fig 1 above, but not marked the same way.
Fig 3 Rough prototype for single cell adapter
This is using the existing parts of the Prism adapter.
Maybe better would be to make a bracket so the battery holder
would stand vertically. When using this battery holder a slight
bump will cause the battery to fall away from the contacts.
Fig 4 rough prototype for single cell adapter.
Standing with wires up. This has two advantages over wires down:
1. the teeth that hold the spring loaded contact will grip and
2. the wires and fixed terminal do not need a big hole in the adapter.
Two of these fixtures could be installed side by side.
