Muraphone KCTC917HSB Replacement Battery 3.6V 700mAh

Muraphone KCTC917HSB — 3.6V Ni-MH Replacement Battery

This is a 3.6V, 700mAh Ni-MH rechargeable battery for the Muraphone KCTC917HSB cordless handset and compatible models including KX165, KX166, and KXA36. It replaces the original pack when charge capacity has dropped and the handset can no longer hold a wireless connection. Voltage and cell count match the original spec exactly.

• KCTC917HSB, KX165, KX166, KXA36 platform: These handsets share the same 3.6V three-cell NiMH configuration and connector pinout, which is why a single pack covers all listed models. The base station charges through the same contact points on each handset.
• Bench tested on actual hardware: We cycled this pack through charge and discharge on a DECT handset base station. The BMS accepted charge cleanly from the first cycle and voltage held stable through the RF transmit bursts during a test call session.
• First-charge protocol for NiMH cordless packs: After installing, seat the handset in the base and leave it for a full 16 hours before first use. NiMH cells in cordless phones need this slow initial charge to activate all cells evenly — skipping it leaves you with less than rated capacity from day one.

Talk time shorter than original battery after replacement

NiMH cells do not reach rated capacity on the first charge cycle — this is normal chemistry, not a fault. A new 700mAh pack typically delivers around 60–70% of its rated capacity for the first three to five full cycles. Each full charge and full discharge cycle conditions the cells further until they stabilise at rated capacity. Run three complete cycles through the base station before judging talk time.

Base station shows no charge light or error after battery swap

NiMH batteries self-discharge during storage, and a pack that has sat in a warehouse can drop below the voltage threshold the base station needs to initiate charging. Some DECT bases read a deeply discharged pack as absent or faulty and refuse to start the charge cycle. Place the handset firmly in the base, leave it undisturbed for 30 minutes, and check whether the charge indicator activates — the trickle current from the base is usually enough to bring cell voltage up to the acceptance threshold. If the light still does not come on, check that the handset contacts are clean and fully seated.
