LONG LASTING - EEMB CR2 3V one-time-use batteries have high energy density that will last 3-5 times longer than alkaline one-time-use batteries when using in high drain devices. These are non-rechargeable/one-time-use/disposable batteries, please DO NOT CHARGE.
WIDELY USE—CR2 lithium battery can be used for flashlight, digital camera(NOT for Arlo cameras), Camcorder, Toys, medical equipment GPS equipment, Intelligent Instrumentation, Electric Meter, Electric Toy, Calculator, Smoke Detector, Electronic Doorbell, MP3.
Photographers and tech enthusiasts who rely on high-drain devices like Fujifilm instant cameras or high-performance flashlights need these EEMB lithium cells to avoid the constant frustration of dying power. Unlike standard alkaline batteries that struggle under heavy loads, these 3V lithium cells offer much higher energy density, lasting three to five times longer in demanding electronics. I found the 850mAh capacity particularly impressive for maintaining steady voltage in everything from digital cameras to medical equipment and GPS units. Because these are non-rechargeable, you must remember never to attempt to charge them, but for a reliable, one-time-use power source, the bulk 10-pack offers incredible utility. It is a professional-grade solution for anyone tired of swapping out weak batteries mid-use.
The most common mistake when shopping for GPS batteries is focusing solely on milliamp-hours (mAh). While a higher mAh rating suggests longer runtimes, it does not account for the discharge rate required by the GPS module. GPS devices are notorious for 'bursty' power consumption—they remain in a low-power sleep mode for most of the time but require a sudden, significant surge of current to acquire a satellite lock or transmit data over a cellular network. If the battery's internal resistance is too high, the voltage will sag during these bursts, causing the device to reboot or fail to establish a connection. Look for batteries that specify high-discharge capabilities or are optimized for lithium-ion/lithium-polymer chemistries, which manage these surges much more effectively than standard cells.
Chemistry and Temperature Resilience
GPS tracking is often used in extreme environments, from logistics vehicles traveling through frozen mountain passes to maritime devices exposed to tropical heat. The chemical composition of your battery dictates its operational window. Lithium-based chemistries are generally the gold standard for GPS applications because they maintain a relatively stable voltage throughout their discharge cycle and perform significantly better in sub-zero temperatures than Nickel-Metal Hydride (NiMH) alternatives. When selecting a battery, check the operating temperature range. A battery rated for -20°C to 60°C is a baseline requirement for professional-grade tracking applications; anything less may lead to premature failure in outdoor or automotive settings.
Form Factor and Integration
EEMB offers various configurations, ranging from cylindrical cells to custom-shaped lithium-polymer pouches. The physical dimensions are a critical decision factor. If you are replacing a battery in an existing, sealed GPS unit, you must match the dimensions and connector types precisely. A battery that is even a millimeter too thick may prevent the device housing from sealing properly, compromising its waterproof rating. Furthermore, pay attention to the protection circuitry. High-quality GPS batteries should include integrated Protection Circuit Modules (PCM) that prevent overcharging, over-discharging, and short-circuiting. This built-in safety layer is essential for protecting both the battery and the expensive GPS hardware it powers.
Cycle Life and Long-term Reliability
If your GPS device is part of a permanent installation, such as an asset tracker on a shipping container, you need a battery with a high cycle life. This refers to how many times the battery can be charged and discharged before its capacity significantly degrades. For rechargeable applications, aim for batteries that promise hundreds of cycles without losing more than 20% of their original capacity. For non-rechargeable primary cells, focus on the shelf life and self-discharge rate. A battery that loses its charge while sitting in a warehouse is useless for emergency tracking scenarios. Prioritize cells with low self-discharge rates to ensure that when the device is deployed, it actually has the energy it claims to possess.

Quick answers about Eemb Gps Batteries before you buy.
Depending on the device and signal strength, a high-quality battery usually provides between 10 to 20 hours of continuous active tracking, though standby time can last for days.
Yes, lithium-ion rechargeable batteries are often preferred for GPS units because they maintain a consistent voltage output and handle extreme temperatures better than standard alkaline cells.
Lithium batteries are the gold standard for cold environments; unlike alkaline batteries, they are chemically designed to resist capacity loss in freezing temperatures.
All batteries undergo chemical degradation, but high-quality rechargeable cells are rated for hundreds of charge cycles before you notice a significant drop in total runtime.
When the signal is weak, the GPS receiver increases power consumption to maintain a connection with satellites, which accelerates battery depletion.
It is best to remove batteries during long-term storage to prevent potential leakage and corrosion, which can permanently damage the device's internal circuitry.
NiMH batteries are budget-friendly but have a higher self-discharge rate, whereas Lithium batteries offer higher energy density and much better performance in low-temperature conditions.
