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.

AEG Teleport 9S/10 — 4.8V Ni-MH Replacement Battery
This is a 4.8V 1200mAh Ni-MH battery for the AEG Teleport 9S and Teleport 10 two-way radios. It slots into the same battery compartment as the original pack and matches the voltage rail the radio's transmit circuit expects. Capacity is rated at 1200mAh / 5.76Wh.
- Teleport 9S and 10 platform fit: Both models share the same 4.8V battery bay, contact layout, and charge termination logic. One replacement covers both radios without any modification.
- Bench tested on actual hardware: We cycled this pack through transmit loads on the Teleport platform. The BMS held voltage above cutoff through sustained PTT presses and recovered cleanly between cycles without tripping lockout.
- First-charge contact check: If the charger shows no response on first insertion, remove the pack and wipe the contact pads with a dry cloth before reseating. The Teleport charger handshakes via contact resistance — oxidation on a new pack's pads is enough to block the charge cycle from starting.
Why the Teleport 9S cuts out mid-transmission on a new battery
A new Ni-MH pack ships at storage voltage — typically 4.2–4.4V rather than a full 4.8V. When you key the PTT on a cold pack, the transmit current spike pulls the cell voltage below the radio's undervoltage cutoff threshold. The radio interprets this as a depleted pack and drops out of TX. Run at least one full charge cycle before expecting the pack to handle sustained transmission loads. After that first cycle, the cells reach working voltage and the sag under PTT load stays within the radio's operating window.
Bar indicator showing one fewer bar than expected after fitting this pack
The Teleport's bar indicator reads voltage thresholds — it does not track charge history. A new pack at storage voltage reads one band lower than a fully charged pack, so the display shows fewer bars even though nothing is wrong. Charge the pack to completion before judging the indicator. Once voltage reaches the full 4.8V, the display steps up to its correct bar count.

Frequently Asked Questions
The charger dock shows a fault LED every time I insert the new pack — it never starts charging. What's wrong?
The Teleport charger checks contact resistance before accepting a pack. If the gold contact pads on the new battery have a thin oxidation layer from storage, the dock reads an open circuit and throws the fault LED. Remove the pack, wipe both contact pads with a dry cloth, and reseat firmly. The fault LED should clear within a few seconds of clean contact.
Radio drops to noticeably weaker TX output partway through a shift — pack still shows bars on the indicator. What's happening?
Voltage sag under sustained RF output is the cause. Ni-MH cells in a 4.8V pack can hold enough voltage to register on the bar indicator while still sagging below the threshold the transmit amplifier needs for full power. This gets worse if the pack hasn't been fully cycled. Run two complete charge-discharge cycles to condition the cells, then recheck TX output — sag under load drops significantly once the cells have been through a proper conditioning cycle.
Pack sat unused for several months and now the charger won't recognise it at all — not even a fault LED, just nothing.
Extended storage below roughly 4.0V total can push a Ni-MH pack below the dock's minimum acceptance voltage. The charger sees no valid voltage signal and ignores the pack entirely. Some chargers can be bypassed by using a compatible external Ni-MH charger set to a trickle or recovery mode — apply a slow charge at low current until the pack reaches approximately 4.2V, then transfer back to the dock. At that point the dock's acceptance circuit can register the pack and resume normal charging.
