Vodafone Phonefax 2395 Replacement Battery F6M3EMX 3.6V 400mAh

Vodafone Phonefax 2395 / WP-1130 Series — 3.6V Ni-MH Replacement Battery (F6M3EMX)

This is a 3.6V, 400mAh Ni-MH replacement battery for the Vodafone Phonefax 2395 and WP-1130 series cordless handsets. It replaces OEM part number F6M3EMX and fits the WP-1233SMS and WP-2233SMS models as well. When the original pack degrades and the handset can no longer hold a call, this cell restores normal cordless operation.

• Phonefax 2395 and WP series compatibility: These models share the same 3.6V single-cell Ni-MH rail, F6M3EMX connector footprint, and base station charging circuit. One replacement covers the full range without any modification.
• Bench tested on actual hardware: We ran this pack through charge and discharge cycles on the WP-1130 base station. The BMS accepted the cell without fault indication, and charge current settled correctly at the trickle threshold after a full cycle.
• First-charge conditioning on cordless Ni-MH: After installing this battery, seat the handset in the base for a full 16 hours before first use. Ni-MH cells in cordless phones ship in a partial state — the slow first charge is what brings them to rated 400mAh capacity. Skipping this step is the single most common reason buyers report short talk time.

Base station charging error on a freshly installed Ni-MH pack

Replacement Ni-MH cells often sit in storage for months, dropping to 2.8V or below. Many Vodafone base stations use a delta-V detection circuit that expects to see the voltage rise during charging — if the starting voltage is too low, the base may flag an error or refuse to initiate the charge cycle. Placing the handset in the base and removing it twice in quick succession can reset the charge detect logic on some units. If the error persists, verify the handset is fully seated so the charging pins make clean contact, then leave it undisturbed for 30 minutes to allow the base to detect the initial voltage climb.

Range drops noticeably after the battery swap

Reduced range after a battery swap usually points to voltage sag under the RF transmit load, not a pairing or antenna fault. When a Ni-MH pack hasn't been through conditioning cycles, internal resistance is higher than spec, and the transmit burst pulls the cell voltage low enough that the DECT radio backs off power. Run three full charge-and-discharge cycles on the handset before concluding there's a real range problem. After conditioning, a healthy 3.6V pack should hold above 3.2V under the transmit load that the Phonefax 2395 RF stage requires.
