  All products carry an unconditional 30 day full refund policy, no questions asked. If the return is due to faulty manufacturing, we will pay return shipping. Returns beyond 30 days in new, uninstalled, and marketable condition will be refunded at current market price.


Unless stated otherwise for a particular product, all items we manufacture carry an UNLIMITED warranty duration against electrical failure from any cause (even sinking, lightning etc.). We will repair and return or if we are unable to correct the problem we will send you a new or reconditioned replacement. Customer pays warranty return shipping to Yandina. We return with (domestic) shipping prepaid. International warranty returns may be charged for return shipping if no problem is found. We reserve the right to void this warranty under unusual circumstances.

On most products the unlimited warranty does not cover failure due to customer installation errors. 15% of Trollbridge battery chargers are destroyed due to failure to follow installation instructions. For installation errors a replacement is made available at reduced price. If applicable an included WARNING sheet will indicate the replacement cost.

Products manufactured by others that we retail have a 30 day warranty.
Retailers may have alternate optional warranty terms.

Liability is limited to the retail price of the item.

No RMA is required but before returning items we strongly suggest you email or call our technical support toll free at 877 355 2184. On average over the last 25 years, over 30% of returns have absolutely nothing wrong with them.

Please include a brief description of the problem and MAKE SURE YOU INCLUDE A RETURN ADDRESS, email address, phone and invoice number if you have it.

CLOSEOUT AND REFURBISHED PRODUCTS. These items are either refurbished returns from customers or factory seconds with cosmetic defects. All carry a full electrical warranty.

Terminals may have been changed, cables extended, fuses added, etc.
