Battery Care Tips
Battery Care Tips
🔹 Getting Started
Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.
🔹 Keep It Healthy
Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.
Delivery and Shipping
Delivery and Shipping
🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

Alcatel 2070 / Altiset Comfort Series — 3.6V Ni-MH Replacement Battery (C39453-Z5-C193)
This is a 3.6V, 600mAh Ni-MH battery pack for the Alcatel 2070, 2570, Altiset Comfort, Daytona, and related cordless DECT handsets. It replaces OEM part numbers C39453-Z5-C193 and HSC22. Install it when the original pack no longer holds enough charge for daily calls.
- Fits the 2070, 2570, and Altiset Comfort range: These handsets share the same battery bay dimensions, connector orientation, and 3.6V NiMH charging circuit. One pack fits the full group without modification.
- Bench tested on actual hardware: We cycled this pack through the Alcatel base station charger and confirmed the BMS accepted charge current without triggering an error light. Voltage held stable across the full discharge curve under normal handset load.
- First-charge protocol for NiMH handsets: After fitting, seat the handset in the base and leave it for a full 16 hours before use. NiMH cells in cordless phones need this slow initial charge to reach rated capacity — skipping it leaves the pack at 60–70% of its 600mAh potential from day one.
Base station error light on a brand-new NiMH pack
Alcatel base stations check incoming voltage before accepting a charge. A new NiMH pack that has sat in storage can drop to 3.0V or below — below the base's acceptance threshold. The base interprets this as a fault and flashes the error light instead of charging. To recover, remove the handset, wait 60 seconds, reseat it firmly, and check the light again. Most bases will accept the pack once contact is re-established and the voltage reading stabilises above 3.2V.
Talk time shorter than expected after the first few uses
NiMH cordless phone batteries do not deliver full capacity straight out of the box. Rated capacity — 600mAh in this case — is reached after three to five full charge-discharge cycles. Early calls will feel shorter than the original battery at its peak. Run the handset down to the low-battery warning, return it to the base for a full charge, and repeat this three times. By cycle four, talk time should match or exceed the original pack's current performance.

Frequently Asked Questions
My Alcatel 2070 loses range near the edges of my home after fitting the new battery — original pack never did this. What's wrong?
NiMH voltage sags under RF load when the pack hasn't been fully conditioned. The handset's transmit circuit draws a short high-current pulse every time it communicates with the base, and an unconditioned cell can't sustain voltage through that spike — so the radio drops signal before the battery gauge shows low. Run three full charge-discharge cycles first. After conditioning, the pack should hold above 3.4V under RF load and restore normal range.
The handset stopped pairing with the base after I swapped the battery — it's showing a registration error. How do I fix this?
Some Alcatel DECT handsets lose their pairing data when power is fully interrupted during a battery swap. The handset needs to re-register with the base. On most Alcatel models, hold the paging button on the base for five seconds until it beeps, then go into the handset menu under Settings → Register Handset and follow the on-screen steps. Once re-registered, the error clears and calls route normally.
The battery drains overnight even when the handset is sitting in the base. It's fully dead by morning.
This points to a seating issue, not a battery fault. If the handset isn't fully clicked into the base cradle, the charging contacts don't make a consistent connection — the base stops charging while the handset keeps drawing standby current. Check that the handset clicks in with light downward pressure and that the charging indicator light stays solid. If the cradle contacts look oxidised, wipe them with a dry cloth before reseating.
