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.

Telecom 810 — 3.6V Ni-MH Replacement Battery
This is a 3.6V, 700mAh Ni-MH replacement battery for the Telecom 810 cordless handset. It fits directly into the handset battery compartment and restores wireless operation when the original cell has degraded. If your 810 is dropping calls, cutting out, or failing to hold a charge between uses, this cell is the direct replacement.
- Telecom 810 handset fit: The 810 uses a single-cell Ni-MH pack at 3.6V to match the base station's charging circuit. Swapping to a different voltage or chemistry will cause charging errors or no-charge detection at the base.
- Bench tested on actual hardware: We cycled this cell through charge and discharge on a Ni-MH test bench. The BMS accepted charge correctly from the base station dock and held voltage through a full discharge cycle without premature cutoff.
- First-charge protocol for Ni-MH handsets: Place the handset in the base immediately after installing and leave it for a full 16 hours before first use. Ni-MH cells shipped in storage state need a slow first charge to reach rated capacity — a short charge will not fully initialise the cell.
Base station charging error on a new Ni-MH pack
Ni-MH cells lose voltage during storage. A deeply discharged cell can arrive at a voltage too low for the base station's charge-detection circuit to accept. The base reads it as a fault rather than an empty battery. Seat the handset in the base and leave it for at least one hour — most bases will begin trickle-charging below the threshold and recover the cell to an acceptable voltage before switching to normal charge mode.
Talk time shorter than original battery after replacement
A new Ni-MH cell rarely delivers full rated capacity on the first cycle. The electrodes need three to five full charge-discharge cycles to reach the 700mAh rating. Each cycle progressively increases available capacity. Run the handset down to the low-battery alert, then return it to the base for a full charge — repeat this process until talk time stabilises.

Frequently Asked Questions
My Telecom 810 base station isn't showing a charging light after I put the new battery in — is the battery dead?
Most likely the cell voltage dropped too low during storage for the base to recognise it as a valid battery. Seat the handset firmly in the base and wait 30–60 minutes — the base will typically trickle-charge the cell up past the acceptance threshold before the charge indicator activates. If the light still does not come on after an hour, remove the handset, check the contacts on the battery and base cradle are clean and making full contact, then reseat it.
My 810 handset is completely draining overnight even though I leave it in the base — why?
A handset draining overnight while docked points to a seating issue rather than the battery itself. If the handset is not fully clicked into the base cradle, the charging contacts do not make a reliable connection and the battery discharges through normal standby draw without recharging. Check that the handset sits flush in the cradle with no gap, and verify the base cradle contacts are free of dust or corrosion — wipe them with a dry cloth and reseat the handset.
My Telecom 810 seems to lose range and cut out near the edges of the house after the battery swap — the original battery didn't do this.
Range drop after a battery swap is usually a voltage-sag issue during the early cycles of a new Ni-MH cell. When the RF transmitter draws current for a signal, a low-cycle Ni-MH pack sags in voltage more than a conditioned one, reducing transmit power. After three to five full charge-discharge cycles the cell firms up and voltage sag under RF load reduces. If range is still poor after five cycles, check the battery contacts in the handset are clean and making full pressure contact with the cell terminals.
