Orders typically ship within 2–5 business days, depending on stock and Hazmat regulations.

How long does shipping take?
Standard U.S. delivery takes 2–9 business days.

How do I track my order?
Once your order ships, you’ll receive an email with tracking information. Hazmat items shipped via USPS may have a tracking delay of 2–4 days.

Can I cancel my order?
Yes—orders can be canceled before they ship for a full refund. If already shipped, please use our return process.

How are Li-Ion and Li-Polymer batteries shipped?

Battery Care & Maintenance

How do I extend battery life?

• Fully charge and discharge new batteries 2–3 times
• Condition NiMH/NiCd batteries monthly
• Store batteries in a cool, dry environment
• Clean contacts regularly with a dry cloth

How long will my battery last?
Typically 1.5 to 3 years, depending on usage and conditions.

What are battery connection types?

• Series: Increases voltage
• Parallel: Increases capacity (Ah)

Battery Knowledge

What's the difference between NiMH, NiCd, and Li-Ion?

• NiMH: High capacity, no memory effect, eco-friendly
• NiCd: Prone to memory effect, contains toxic metals
• Li-Ion: Lightweight, no memory effect, widely used today

What is the "Memory Effect"?

This affects NiCd batteries, reducing capacity over time when not fully charged or discharged.

What does battery capacity mean?

It refers to how much energy a battery stores, measured in mAh (Milliamp-hours) or Ah (Amp-hours).

What is battery chemistry?

It describes the chemical composition that powers the battery—e.g., Li-Ion, NiMH, or NiCd.

What is voltage?

Voltage is the electrical pressure that powers your device. Using the correct voltage is crucial to safety and performance.

Charging & Usage

What's the difference between a Rapid and Trickle Charger?

• Rapid Charger: Charges up to 80% in 1–2 hours
• Trickle Charger: Slower (10–12 hours), ideal for overnight charging

How should I charge my battery?

Use an automatic charger. Insert the battery, wait for the red (charging) light to turn green (fully charged). The charger then enters maintenance mode.

What is a battery cycle?

One full charge + discharge = 1 cycle. Most batteries are rated for a specific number of cycles (e.g., 300–500).

Smart Batteries & Chargers

What are Smart Batteries?

These batteries communicate with smart chargers to display real-time data on performance and health.

What are Smart Chargers?

They go beyond charging—displaying battery health, adaptive reconditioning, and maintenance alerts.

What’s the difference between standard and smart chargers?

• Standard Rapid Chargers: Fast but basic—no diagnostics
• Smart Chargers: Feature LCD displays and monitor battery condition and lifespan

What is an Intrinsically Safe (IS) battery?

IS batteries are designed for use in hazardous environments—safe to use around flammable gases or dust.
