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

🔹 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.

Rapoo Ti100 — 3.7V Li-Polymer Replacement Battery (AHB102050PJT)

This is a 3.7V, 900mAh Li-Polymer battery for the Rapoo Ti100 wireless headset. It replaces part number AHB102050PJT directly. Fits the Ti100 only — check your OEM part number before ordering.

  • Ti100 cell fit: The Ti100 runs a single-cell Li-Polymer pack at 3.7V nominal. The BMS in the headset monitors cell voltage and current draw across both the audio codec and the Bluetooth radio simultaneously — the replacement cell must match the original voltage profile or the BMS will cut power early.
  • Bench tested on actual hardware: We cycled this cell through combined Bluetooth radio and audio load. The BMS accepted the new pack without error, held voltage above 3.4V under sustained draw, and completed a full charge cycle from the base station without a fault flag.
  • Base station first charge: Seat the headset in the base station immediately after fitting and leave it for a complete charge cycle before use. The Ti100's talk-time counter reads from the base station's charge log — if the base hasn't completed one full cycle with the new cell, the displayed talk-time estimate will be inaccurate.

Why the Ti100 cuts out mid-call even with a new battery fitted

The Ti100 pulls current from two sources at once — the audio driver and the Bluetooth radio. During an active call, this combined draw briefly spikes above what the BMS expects from a cell at storage voltage. If the new cell hasn't been through a full charge cycle, resting voltage sits around 3.6–3.7V but the BMS still trips on the spike. One complete charge-discharge cycle brings the cell up to full capacity and stabilises the BMS response to those draw spikes.

Base station shows full charge but headset dies after a few minutes

This happens when the cell arrives at storage voltage — typically 3.75–3.80V — and the base station interprets that as a near-full charge, terminating the cycle early. The cell never reaches true full capacity. The fix is to discharge the headset fully with a call or audio playback, then return it to the base for a complete uninterrupted charge. After one proper full cycle, the base station's charge termination logic resets to the correct cutoff point for the new cell.

Frequently Asked Questions

My Rapoo Ti100 keeps dropping out mid-call even though the battery is new — what's causing it?

The Ti100 runs the Bluetooth radio and audio driver off the same cell at the same time, and that combined current spike can trip the BMS if the new cell is still at storage voltage. This isn't a fault with the battery — it's the BMS reacting to a spike it doesn't expect from a partially charged cell. Do one full charge cycle in the base station before making a call, and the cutouts should stop. If they continue after three full cycles, check that the cell is seated flat with no gap at the connector.

The base station is showing a charging error after I fitted the replacement cell — how do I clear it?

The base station runs a BMS handshake when a new cell is detected. If the cell voltage is outside the expected range on first insertion — common with cells shipped at storage voltage — the base logs a fault rather than beginning the charge cycle. Remove the headset, wait 10 seconds, and reseat it firmly in the dock. In most cases the base re-initiates the handshake and begins charging normally. If the error persists, confirm the connector is fully engaged — a partial connection keeps the BMS from reading cell voltage correctly.

Talk time is noticeably short for the first few days after fitting — is the battery faulty?

It isn't faulty. Li-Polymer cells need three to five full charge-discharge cycles before they reach rated capacity. On the first cycle the cell typically delivers 80–85% of rated capacity, then steps up with each subsequent cycle. Run the headset down on calls or audio until it shuts off, then charge fully in the base station — repeat this three times and talk time will be close to the 900mAh rated figure.
