Frequently Asked Questions

Q: Are SHENTEC batteries as good as the original (OEM) ones?

A: Yes! SHENTEC batteries are designed to meet or exceed the original manufacturer's specifications. We use high-quality cells and are CE/FCC/RoHS certified to ensure the same performance and safety at a more affordable price.

Q: Will using a SHENTEC battery void my tool's warranty?

A: Generally, no. Using a high-quality third-party battery does not void your tool's warranty in most regions (like the US under the Magnuson-Moss Warranty Act). We ensure 100% electronic and physical compatibility.

Q: How do I choose the correct battery for my model?

A: Please check your original battery's Part Number or your tool's Model Number. You can use the "Search" bar on our website or contact our support team to double-check compatibility before purchasing.

Q: What does "Ah" mean? Can I use a higher Ah battery?

A: "Ah" (Amp-hour) refers to the battery's capacity (how long it lasts). You can use a higher Ah battery (e.g., replacing a 2.0Ah with a 5.0Ah); it will provide longer runtime per charge without damaging your tool.

Q: How many cycles can I expect from a SHENTEC battery?

A: Our batteries are built for longevity, supporting up to 1,200 fast-charge cycles. With proper care, they can serve you for years.

Q: How should I store my battery if I’m not using it?

A: Store it in a cool, dry place. For long-term storage, keep the battery at 40%–60% charge. Our batteries feature low self-discharge, retaining about 70% power even after 3 years of storage.

Q: Does the battery have safety protections?

A: Absolutely. Every SHENTEC battery has a built-in Smart Protection System that guards against overcharging, over-discharging, short-circuits, and overheating.

Q: Why does my new battery arrive with a partial charge?

A: For safety during shipping, batteries are usually charged to about 30%. We recommend fully charging your battery before its first use to calibrate the cells.

Q: How long does shipping take?

A: We ship from our local warehouses in the USA, Germany, UK, and Australia. Most orders are delivered within 3-5 business days.

Q: What is your return policy?

A: We offer a 30-Day FREE Return & Replacement policy for any reason. If you ordered the wrong model or are not satisfied, we’ve got you covered.

Q: What is the warranty period?

A: All SHENTEC products come with a 12-Month Limited Warranty. If the product fails due to a manufacturing defect within one year, we will provide a free replacement.

Q: What should I do if my battery won't charge?

A: First, ensure the charger is compatible and the contacts are clean. If it still doesn't work, contact us at sales@shentec.com with your order ID, and we will help you troubleshoot or send a replacement.
