Centenex DS-CS-FMB400SL GPS Battery

The Centenex DS-CS-FMB400SL is a 9.6V 3.6Ah Ni-MH replacement battery designed for Okuma GPS systems. It suits technicians and operators maintaining compatible MB4000 series devices. This unit delivers 34.56Wh of capacity in a black housing. It arrives new and 100% OEM compatible.

Fits Okuma MB4000 and MB4000a units directly

The battery replaces part numbers 8HR-4/3FAUPC and E5503-07E-001 without modification. It slides into the existing compartment and connects to the original terminals. This frees the GPS device from mains dependency during mobile operation. One battery is supplied per package.

Ni-MH chemistry provides stable voltage under load

The 3600mAh capacity supports extended field sessions between charges. Ni-MH cells exhibit low self-discharge and contain no liquid electrolyte to leak. Normal use produces no audible noise and minimal heat. The 70.36 x 67.88 x 34.52 mm form factor matches the original enclosure exactly.

Questions about this item

How long will the 3.6 Ah capacity last under continuous GPS operation?

The 3.6 Ah Ni-MH pack delivers 34.56 Wh at 9.6 V; runtime depends on the GPS unit's current draw, so divide its consumption into 3.6 Ah for an estimate.

Does the battery get hot or noisy during all-day use?

Ni-MH chemistry runs silently and generates only moderate warmth; no fan or moving parts are present, so heat stays low under normal GPS loads.

Which Okuma models must I already own for this pack to fit?

It replaces part numbers 8HR-4/3FAUPC and E5503-07E-001 in Okuma MB4000, MB4000a and MB-4000H units; verify your device uses one of those codes.
