How to Compare Tenergy Coupon Codes and Sale Prices

A Tenergy saving can come from a coupon code, a marked-down price or free shipping.

• The storewide codes we tested each take 5% off every item in the cart, so they save the most on high-priced products such as power stations and LiFePO4 batteries.
• Marked-down products in the Deals section show a "Was" price and the amount saved.
• Many products are labeled Free Shipping, and the free shipping credit is limited to $25.00 per order.
• Tenergy collects sales tax only on orders shipped to California, so the Grand Total in the cart can differ by state.

The Coupon line and the Grand Total in the cart are the numbers to compare before you check out.

What to Check Before a Tenergy Order

Batteries have shipping rules of their own, so check a few details before you pay.

• Free shipping applies only to domestic U.S. addresses outside Hawaii and Alaska, and not to oversized or freight orders, Second Day or Next Day orders, or orders that need Class 9 or Hazmat fees.
• Orders are processed in 1 to 2 business days. Orders placed after 8:00 AM Pacific time start processing the next business day, and first-time purchases may need a phone payment verification that adds 1 business day.
• International shipping is available by UPS and USPS, but Class 9 battery shipments add a fee per box and some products cannot ship abroad.
• Warranty periods differ by product: 90 days for rechargeable batteries and battery packs and 1 year for chargers.

You can return a purchase within 30 days of the purchase date with an RMA number, at your own shipping cost. Items must be new and in their original box, or Tenergy can refuse the return or charge a restocking fee of at least 15%, and refunds on orders that used free shipping or a coupon code can be charged the shipping cost.

Why a Tenergy Coupon Code May Not Work

A Tenergy coupon code can be valid and still give no saving on a specific order.

• The code is limited to selected products, and none of them are in the cart.
• Promotional codes cannot be stacked, so a second code replaces or is refused next to the first.
• The free shipping offer needs an order over $50 and a lower 48 delivery address.
• The code has expired or was removed by the store.
• The code was typed with a different spelling or an extra space.

If a code still does not apply, Tenergy support can be reached at (510) 979-9969, Monday to Friday, 9:00 AM to 5:00 PM Pacific time, or by Live Chat on the site.

Tenergy Coupon Code & Sale-Item Strategy

Check the Deals section first, because marked-down items such as the T600 and T320 power stations already show their savings, then add a storewide code in the cart for another 5% off. On small battery orders, build the cart past $50 so the free ground shipping offer applies, and remember that only one promotional code can be used per order.
