Reolink Battery-Li19 Spare Battery (RLA-LBG1)｜For Go Plus / Go Ultra Only, USB-C Charging

Go Plus／Go Ultra Original Battery｜USB-C Charging｜Solar Panel Compatible｜Swap and Go

Product Overview

Battery-Li19（RLA-LBG1）is a replacement battery provided by Reolink for the Go Plus and Go Ultra 4G battery-powered cameras. The battery is the only component of a battery-powered camera that naturally ages over time — after two to three years of use, the actual capacity of a typical lithium battery will noticeably decrease, reducing battery life from “several weeks” to “several days”.

The specifications on this page are sourced from the **official product summary provided by the distributor**: Battery Li19, compatible with Reolink Go Plus and Go Ultra, with USB-C charging. The official summary does not list the battery capacity (mAh／Wh), so we do not speculate on a specific figure; if you require the exact capacity, please contact us for the information shown on the original packaging.

The practical value of purchasing a spare battery: install one in the camera and keep one on hand, so you can swap it directly when the battery runs out without waiting for it to charge. For 4G cameras installed in high or remote locations, this arrangement saves not only time but also the risk of climbing a ladder each time.

Six Key Highlights

Why a Battery-Powered Camera Needs a Spare Battery

The battery life of a 4G battery-powered camera depends on the trigger frequency and signal strength, and in actual use it is often shorter than expected. When you only have one battery, the camera is completely out of service while it is charging — for those monitoring a warehouse or parking space, this creates a period without any footage.

A spare battery solves exactly this downtime: swapping the battery takes only one or two minutes, while the old one can charge slowly and the camera continues operating without interruption. This is the key accessory that turns a battery-powered camera from a “toy” into a practical tool.

• Minimal downtime when changing the battery
• Suitable for installation in high or remote locations
• Original specifications, without affecting warranty coverage

Natural Lithium Battery Ageing and When to Replace It

All lithium batteries age over time; this is a chemical characteristic. Common signs include: noticeably shorter battery life at the same trigger frequency, the battery showing full very quickly while charging, and rapid power loss after reaching full charge. If your camera has been in use for more than a year and shows these symptoms, the battery is usually the issue rather than the camera itself.

Replacing it with an original battery is more reliable than buying a third-party compatible battery: the voltage curve, protection board and charging protocol are all properly matched, avoiding situations such as “showing full battery but shutting down after half an hour” or abnormal charging.

• Significantly reduced battery life is a sign of ageing
• An original battery is recommended for replacement
• Third-party battery voltage curves may not match

USB-C Charging and Solar Panel Compatibility

The official summary specifies USB-C charging. This means you can use a standard phone charger, power bank or car charger to recharge it, without carrying a dedicated charging dock — very convenient for on-the-go charging or camping.

The battery can also be used with a Reolink solar panel: the solar panel continuously tops it up during daily use, while the spare battery can be swapped in after prolonged rainy weather. This combination allows a 4G camera to operate in a state close to “long-term maintenance-free” use.

• USB-C charging, compatible with standard chargers
• Compatible with Reolink solar panels
• Spare battery for prolonged rainy weather

Compatible Models: For Go Plus and Go Ultra Only

The official summary clearly states that it is compatible with Reolink Go Plus and Go Ultra. These two models are bullet-style 4G cameras; other models in the same series (Go PT Plus、Go PT Ultra、Go Ranger PT、TrackMix LTE、Altas Go PT) use batteries with different specifications and are not interchangeable.

Please confirm your camera model before placing an order. If you are unsure, send us a photo of the model number on the camera body or the label in the battery compartment, and we will help verify it.

• Compatible with Go Plus and Go Ultra
• Not compatible with other Go series models
• If you are unsure, please contact us for confirmation first

Installation and Storage Notes

When replacing the battery, power off the device first and remove the old battery. Pay attention to the position of the waterproof gasket in the battery compartment—make sure the gasket is properly seated when reinstalling it; otherwise, rainwater may seep through the gaps. This is the most common cause of water ingress in outdoor cameras.

For long-term storage (such as throughout the winter), we recommend charging the battery to around 50% before storage. Do not store it fully charged or completely discharged for extended periods, as both conditions will accelerate capacity degradation.

• Make sure the waterproof gasket is properly seated when reinstalling the battery
• Store the battery with around 50% charge for long-term storage
• Avoid storing in high-temperature environments

Care and Purchase Recommendations

Batteries are consumables, and standard warranty terms may have specific provisions for the natural capacity degradation of batteries. If an issue occurs during the warranty period (such as failure to charge or sudden power loss), please contact us first for information about the service process.

Recommended setup: one spare battery per camera. If you have two or more 4G cameras, one spare battery is sufficient for rotation; for three or more cameras, consider having two spare batteries to avoid all devices running out of power at the same time.

• Batteries are consumables; please check the warranty terms
• We recommend one spare battery per camera
• Multiple-camera systems can share spare batteries
