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.

Ring Power Pack — 10.8V Li-ion Replacement Battery (5F35E9)
This is a 10.8V, 8550mAh lithium-ion replacement battery for the Ring Power Pack. It fits Ring video doorbells and security cameras that rely on the Power Pack for continuous operation where hardwiring isn't an option. Match your existing Power Pack unit before ordering.
- Ring Power Pack platform: The Power Pack uses a single high-capacity cell block at 10.8V to sustain the camera's standby draw, WiFi radio, and burst current during motion events. Voltage rail and connector pinout must match — this cell block replicates the OEM spec at 10.8V with an integrated BMS.
- Bench tested on actual hardware: We cycled this battery through standby draw simulation and motion-event current spikes. The BMS held cutoff thresholds correctly at both the low-voltage floor and the peak IR LED plus processor draw during night-vision triggers.
- First-install power cycle: After swapping the battery, power cycle the camera once through the Ring app. The firmware must re-register the new cell before motion events log correctly to cloud storage — skipping this step causes missed recording clips even when the battery reads full charge.
Camera going offline in the Ring app after battery installation
Swapping the battery cuts power momentarily, which causes the camera to drop its session token with the Ring cloud. The app loses the device handshake and shows the camera as offline even after power returns. This isn't a fault with the battery — it's a firmware re-registration issue. Open the Ring app, go to Device Health, and run a reconnect cycle to restore the cloud link.
App reporting 0% or incorrect charge percentage after install
Ring cameras use a voltage-threshold indicator, not a fuel gauge IC. When a new battery is installed, the camera reads the resting voltage and maps it to a charge percentage — but the calibration only stabilises after one full charge and discharge cycle. A brand-new cell at partial charge will often display 0% or an implausible low figure until the threshold mapping resets. Run one full charge through the Power Pack, then check the app again.

Frequently Asked Questions
My Ring camera stops recording mid-clip — could the new battery be cutting out?
Yes, this is a known BMS trip caused by a WiFi reconnect current spike. When the camera loses signal briefly and reconnects, the combined draw from the WiFi radio and processor briefly exceeds the BMS threshold, which trips protection and interrupts the recording. It isn't a battery fault — move the camera closer to the router or add a WiFi extender to reduce reconnect frequency. If the drops continue, check that the Power Pack contacts are clean and fully seated.
The Ring app shows the camera is online but motion detection has stopped working after I swapped the battery.
This is a firmware logging issue, not a motion sensor fault. The camera's motion recording log loses sync when power is interrupted during a battery swap. The IR LED and processor fire on trigger, but clips don't reach cloud storage because the session isn't re-registered. Power cycle the camera through the Ring app under Device Settings, wait 60 seconds, then walk past the camera to force a test trigger.
My solar panel was keeping the Ring Power Pack charged all summer, but it stopped recovering the battery over winter — what's happening?
Solar panel output drops significantly in winter due to lower sun angle and shorter daylight hours. If the Power Pack battery discharges below the BMS re-entry voltage threshold — typically around 9V for a 10.8V cell block — the BMS locks out charge acceptance and the solar panel's reduced output can't push past that floor. Connect the Power Pack to a USB-C mains charger to recover the cell above the re-entry threshold first. Once voltage is above the BMS floor, solar charging resumes normally.
