Alternator Protection Module APM12 - 12V
Alternators can be subjected to voltage spikes caused by lithium battery shutdowns, intermittent connections, and other over-voltage events. Balmar has introduced a robust Alternator Protection Module which helps to protect the alternator’s diodes and internal voltage regulator against spikes (clamping up to 60V) and sustained over-voltage conditions (beginning around 20V for the 12V version). The APM can absorb multiple surges of such energy and can absorb surges in excess of 200 amps without failure to continually protect your alternator. Visual and audible alarms indicate if the device has been compromised and needs replacement.
Balmar APM devices provide intelligent, robust, solid-state protection in a small easily mounted package at the rear of the alternator between the B+ and B- terminals. Balmar APM devices can be used to protect all alternator brands. Balmar APM devices meet ISO 16750-2 for Load Dump Protection and ISO 7637-2 for Surge Protection.

We ship worldwide from the United States. Rates are calculated at checkout based on destination and package weight. Some items include free shipping, which will show automatically.

Processing and dispatch
Most orders are verified, packed, and handed to the carrier within 1 to 2 business days. Some products may need extra handling time or ship directly from the manufacturer. For certain international orders, inventory transfers between warehouses may add time. If any delay is expected, we will let you know the dispatch date.
Delivery and tracking
Deliveries are handled by trusted carriers such as USPS, UPS, FedEx, and DHL. Estimated arrival times appear at checkout and depend on your location and the service you choose. These are estimates and can be affected by customs or carrier disruptions. A shipping confirmation with a tracking link is emailed when your order ships, and tracking may take up to 24 hours to update. You can also view tracking in your account.
Duties, taxes, and support
International customers are responsible for any customs duties, taxes, and fees charged by the destination country. If these charges are refused and a shipment returns to us, the carrier’s return cost and any re-entry customs fees will be deducted from the refund. If your order is late or you need help, contact cs@qualityboatparts.com and we will assist you.
Quality Boat Parts is a reseller. Many items include a manufacturer’s warranty, and all warranty service is handled directly by the manufacturer. We do not manage or administer warranty claims on behalf of customers.
Warranty terms, coverage, and duration are set by each manufacturer. Issues involving defects, repairs, or replacements must be addressed with the manufacturer’s support team. When available, the warranty period is listed on the product page. If it is not shown, contact us or the manufacturer for details before purchasing.
To start a claim, the customer must contact the manufacturer and follow their process. Keep your proof of purchase and original packaging, and register the product if the manufacturer requires it, as these are often needed for warranty service.
We are happy to help you find the right contact or documentation, but we cannot decide outcomes or intervene in claim resolutions. For guidance, email cs@qualityboatparts.com.
