Centenex 7.2V 3500mAh Ni-MH GPS battery

This Centenex DS-CS-RSH300SL pack supplies 7.2 volts and 3500 mAh of nickel-metal-hydride energy in a blue housing. It is built as a direct replacement for the original cells used in Rohde & Schwarz FSH series spectrum analysers and field-test instruments. Technicians who need a fresh, factory-new power source for portable RF measurements will find it matches the OEM form factor.

Sustained discharge profile

The 3.5 Ah nickel-metal-hydride chemistry delivers steady current through extended field sessions without the sharp voltage sag seen in high-rate bursts. Internal resistance remains stable as the pack warms, so the analyser maintains calibrated output power across long sweeps. Self-discharge is low enough that a charged unit left in a kit bag retains usable capacity for weeks between jobs.

7.2V Ni-MH interface limits

The pack presents a nominal 7.2 V output with a 25.20 Wh energy rating, defining the maximum run-time envelope for any compatible FSH instrument. Charging must follow standard Ni-MH constant-current/constant-voltage profiles; exceeding the specified voltage or current will degrade cycle life. Physical dimensions of 134.82 x 33.90 x 31.60 mm fix the battery-compartment clearance, so enclosures designed for thinner or shorter cells cannot accept this unit.

Questions about this item

Does the 7.2 V 3500 mAh Ni-MH pack run hot during all-day field use?

The Ni-MH chemistry stays cool under normal load; no active cooling is required and the blue housing remains comfortable to touch.

Which Rohde & Schwarz analyser must I already own for the DS-CS-RSH300SL to fit?

It fits the FSH3, FSH6, FSH18, FSH323, FSH626 and FSH-Z32 models listed in the compatibility table.

Will this 25.20 Wh replacement work in an older FSH3 unit that originally shipped with a lower-capacity pack?

Yes, the voltage and connector match the original specification, so the older analyser will recognise and charge the 3500 mAh cell normally.
