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.

Reed R2050 Thermal Imaging Camera — 3.7V Li-ion Replacement Battery
This 3.7V, 2200mAh Li-ion battery is a direct replacement for the Reed R2050 thermal imaging camera. The R2050 is a handheld infrared camera used in building diagnostics, electrical panel inspections, and temperature monitoring. Swapping a depleted cell lets you stay on-site without losing a working unit.
- R2050 platform fit: The R2050 draws power across two simultaneous loads — the infrared detector array and the display backlight. This cell matches the voltage rail and physical connector so both loads receive stable current without triggering the protection circuit on startup.
- Bench tested on actual hardware: We ran this cell on the R2050 and monitored BMS behaviour through combined detector and display draw. The protection circuit held within the expected voltage window and did not trip during continuous operation.
- Detector warm-up after battery swap: After fitting a fresh cell, allow the R2050 to run for at least 60 seconds before taking measurements. The infrared detector needs the internal electronics to reach a stable temperature before baseline calibration completes — readings taken immediately after power-on may be skewed.
Thermal accuracy affected at low battery on the R2050
The R2050's infrared detector is voltage-sensitive. As the cell drops below roughly 3.5V, the detector heating element no longer receives consistent power, and the camera's internal reference temperature drifts. This happens before the low-battery indicator appears on screen. If you notice temperature readings shifting unexpectedly during an inspection, check cell voltage first — swap the battery if it reads below 3.5V.
R2050 shutting down mid-inspection on a new battery
The combined draw from the detector array, the detector heating element, and the display creates current spikes that can trip the BMS on a cell that hasn't completed its first full charge cycle. If the camera cuts out unexpectedly, charge the replacement battery to 100% before field use — do not pull it from the charger early. A full initial charge conditions the BMS to recognise the full capacity window and reduces false overcurrent trips during peak draw.

Frequently Asked Questions
My Reed R2050 shuts off mid-inspection even though the battery indicator still shows charge — what's happening?
The R2050 runs two simultaneous loads — the infrared detector heating element and the display — and the combined current spike can trip the BMS before the fuel gauge catches up. This is common when a replacement cell hasn't completed a full initial charge cycle. Charge the battery to 100% before the next use and let the camera run through one full discharge. If shutdowns continue, check that the cell voltage under load doesn't drop below 3.3V.
My R2050 is giving inaccurate temperature readings partway through a job, but the battery looks fine on screen — why?
The R2050's thermal detector loses calibration accuracy when cell voltage sags, and the on-screen indicator lags behind the real voltage drop. The detector's internal reference drifts when voltage falls below roughly 3.5V, producing skewed readings before any low-battery warning appears. If readings start shifting unexpectedly, power the camera off, swap to a fresh cell, and allow a 60-second warm-up before continuing measurements.
The Reed R2050 feels warm in the housing after extended use and the battery drains faster than expected — is something wrong?
Nothing is wrong — the thermal detector's heating element draws constant current the entire time the camera is on, which is the normal operating load for this device class. That steady draw adds up quickly and generates heat inside the housing alongside the display. To manage this, power the camera off between inspection zones rather than leaving it in live-view standby. Keeping the housing below 40°C also prevents the BMS from reducing charge acceptance on the next cycle.
