How Can You Identify If Your Fenix PD35 Flashlight Battery Needs Replacement?

You can identify if your Fenix PD35 flashlight battery needs replacement by monitoring its brightness, checking for flickering, observing a decrease in run time, and noting if it fails to turn on.

• Brightness: If the flashlight’s brightness diminishes significantly, it may indicate that the battery is running low. A fully charged Fenix PD35 should provide bright light consistently. Reports suggest that a distinct drop in performance is often linked to battery depletion (Fenix, 2023).

• Flickering: If the beam starts to flicker, this can signal intermittent power delivery. This is often caused by an insufficient charge in the battery. Continuous flickering typically suggests that the battery cannot maintain a stable output, confirming the need for replacement.

• Decrease in run time: If you notice that the flashlight’s operational time has substantially shortened, it may be a sign that the battery has lost its capacity. Normal runtime for a Fenix PD35 with a fresh battery is several hours on the highest setting. A significant reduction in this duration indicates that the battery should be replaced.

• Failure to turn on: If the flashlight fails to illuminate when switched on, this is a clear indication that the battery is likely dead or has insufficient power. Inconsistent power can be resolved by replacing the battery.

Regularly monitoring these performance aspects can help ensure your Fenix PD35 flashlight remains functional and ready for use.

What Types of Batteries are Compatible with the Fenix PD35 Flashlight?

The Fenix PD35 flashlight is compatible with two types of batteries: the rechargeable 18650 lithium battery and the non-rechargeable CR123A lithium battery.

1. Rechargeable 18650 lithium battery
2. Non-rechargeable CR123A lithium battery

Understanding the compatibility of the Fenix PD35 flashlight with these battery types is crucial for optimal performance and usage.

1. Rechargeable 18650 Lithium Battery: The Fenix PD35 flashlight supports the rechargeable 18650 lithium battery. This battery type is commonly used in high-performance flashlights due to its capacity and rechargeability. A fully charged 18650 battery provides a longer run time, enabling the flashlight to output higher lumens consistently over more extended periods. This battery typically has a capacity of 2200mAh to 3500mAh, allowing for varying brightness levels depending on the mode used. According to a 2021 analysis by Battery University, the 18650 battery can sustain up to 500 charge cycles, making it a cost-effective option over time.

2. Non-rechargeable CR123A Lithium Battery: The Fenix PD35 flashlight is also compatible with non-rechargeable CR123A lithium batteries. These batteries are often favored for their long shelf life and excellent performance in extreme temperatures. A standard CR123A lithium battery typically has a capacity of about 1500mAh, which may result in shorter run times compared to the 18650 battery. However, they are conveniently available in stores and don’t require a charger, making them suitable for emergency situations. Despite their shorter lifespan, CR123A batteries can remain viable for up to ten years in storage, making them a reliable backup option.

In conclusion, both battery types offer unique advantages, allowing users of the Fenix PD35 flashlight to choose based on their specific needs and preferences.
