Learn practical steps to maximize your TASER Pulse 2 battery life between charges, including storage tips, charge habits, and maintenance checks.

Quick Answer

To extend your TASER Pulse 2 battery life between charges, store it at room temperature, avoid full discharges, and recharge every 3-4 months even if unused. Proper storage and periodic top-ups can keep the battery healthy for years.

Why Battery Care Matters for Your TASER Pulse 2

The TASER Pulse 2 uses a rechargeable lithium-ion battery pack. Like all lithium batteries, its capacity gradually decreases with age, but how you store and charge it has a big impact on how long it holds a useful charge. The Pulse 2 is designed for everyday carry, so a dead battery when you need it defeats the purpose. Simple habits can keep it ready.

One common oversight is leaving the device in a hot car or direct sunlight. High temperatures accelerate chemical degradation inside the battery, permanently reducing runtime. Similarly, storing it fully discharged for months can cause the battery to enter a deep discharge state that may not recover.

Steps to Extend TASER Battery Life

Store at Moderate Temperatures: Keep your TASER Pulse 2 in a cool, dry place between 50°F and 80°F (10°C–27°C). Avoid glove compartments, windowsills, or any spot that gets hot in summer or freezing in winter. Heat is the #1 enemy of lithium batteries. Even short exposure to 100°F+ can permanently reduce capacity.
Avoid Full Discharges: Don't let the battery run completely flat before recharging. Lithium-ion batteries last longest when kept between 20% and 80% charge. Recharge when the low-battery indicator appears, not after the device shuts off. Deep discharges stress the battery chemistry. Top up early to prolong overall lifespan.
Recharge Every 3–4 Months When Not in Use: If you carry your Pulse 2 rarely or store it as a backup, set a calendar reminder to recharge it every 3–4 months. A battery left at 0% for months may never hold a charge again. Even unused batteries self-discharge. Periodic top-ups prevent irreversible damage.
Use the Correct Charger: Always use the charger that came with your TASER Pulse 2 or a certified replacement. Third-party chargers may deliver incorrect voltage or current, leading to overheating or reduced battery life. Stick with the manufacturer charger to avoid electrical damage.
Inspect the Battery Contacts: Every few months, open the battery compartment and check the metal contacts for dirt, corrosion, or debris. Clean gently with a dry cloth or isopropyl alcohol if needed. Poor contact can cause the device to think the battery is low. Clean contacts ensure accurate charge readings and reliable performance.
