How many spare POC batteries can I bring on a plane?

For batteries under 100 Wh (which covers most Inogen and OxyGo single and double batteries), the FAA sets no numerical limit—but you must be able to physically carry them. Use the 150% rule based on your total transit time to determine the exact number you need.

Can POC batteries go in checked luggage?

No. All spare lithium-ion batteries must be in your carry-on baggage. Only the battery currently installed in the device may be in checked luggage (inside the device). This rule is non-negotiable under FAA Advisory Circular AC 120-76E.

High-Performance Power Tool Replacement Batteries

Upgrade your tools with top lithium-ion replacement batteries. They work with Craftsman, DeWalt, EGO, Milwaukee, Bosch, and more. High-capacity options (up to 8.0Ah) provide longer runtime. Built-in safety protections—like overcharge, overheat, and short-circuit—ensure reliability. All batteries come with a 1-year warranty and a 100% compatibility guarantee.

Expert Buying Guide: How to Choose the Right Replacement Battery

Voltage (V) vs. Amp-Hour (Ah) – Voltage determines tool power compatibility; always match the original voltage (18V, 20V, 40V, etc.). Ah rating affects runtime: a 8.0Ah battery lasts up to 2x longer than a 4.0Ah, ideal for heavy-duty jobs. Our high-capacity cells keep a steady voltage. This lets you work longer without damaging your tools.

OEM vs. High-Quality Replacement – Third-party batteries using top LG or Samsung cells provide similar performance. They cost 40% less. Our batteries have a smart BMS (Battery Management System). This system stops over-discharging and helps extend the battery's cycle life.

Pro Maintenance Tips (From Field Experts) – To maximize the lifespan of lithium-ion batteries:

Don’t store them at full charge in high heat.
Never fully deep-discharge them.
Use only compatible chargers.

Frequently Asked Questions

Are replacement batteries safe for my original power tools?

Absolutely. We engineer our batteries with smart BMS and identical voltage specs. They fit seamlessly with OEM chargers and tools. They provide equal or better runtime and won’t void tool warranties.

Does a higher Ah mean more power or longer runtime?

Higher Ah (Amp-hour) increases runtime, not raw power. For example, a 8.0Ah battery will run a drill much longer than a 2.0Ah, perfect for extended jobs. Power (torque) stays consistent as long as voltage matches.

How do I know if this battery fits my Craftsman V20 charger?

Our Craftsman-compatible batteries align seamlessly with V20 series chargers. They have the correct slide interface and contact alignment. Check the product title: e.g., “20V 8.0Ah for Craftsman V20” ensures perfect fit.
