Monster Marine Lithium Warranty Policy

Monster Marine Lithium’s 15 Year Warranty
Monster Marine Lithium’s “MML” warranty consists of three Tiers as described below.

Monster Marine Lithium offers an industry best 15 Year Warranty.
MML 15 Year Warranty consists of Tier 1, Tier 2, & Tier 3 benefits. Prohibited Actions and exclusions (described below) apply.

Free lifetime technical support & free battery analysis. Batteries and chargers must be registered within 60 days of purchase date. If the battery or charger is not registered within 60 days of purchase warranty will be based on the manufacturer date of the battery.

Battery Tier Term Limits Start at Purchase Date

Tier 1 Term Limit: Years 0 to 5
Tier 2 Term Limit: Years 5 to 10
Tier 3 Term Limit: Years 10 to 15

Tier’s Defined
Tier 1: Years 0-5. Manufactured Defective Battery is replaced at no cost to owner throughout Tier 1 term limit (no charge cycle limitation). MML is responsible for returning shipping labels to MML’s address and will supply return shipping labels via email to battery owner. Battery owner is responsible for return shipping cost from MML’s address to battery owner’s address.

Tier 2: Years 5-10. Manufactured Defective Battery is repaired at no cost to owner throughout Tier 2 term limit, while there will be a 2000 charge cycle limitation throughout Tier 2. This clause means between 2000 & 2500 charge cycles the battery is deemed to be in Tier 3 and falls under Tier 3 warranty provisions. Throughout Tier 2 battery owner is responsible for all shipping costs. If battery can not be repaired a 50% pro rate will be offered to original purchaser of battery.

Tier 3: Years 10-15. Manufactured Defective Battery is repaired (please allow 2 weeks minimum for repairs), battery owner is responsible for repair parts cost, if not repaired, battery can be replaced at 30% from current MSRP. Battery owner throughout Tier 3 term limit is responsible for all costs to replace the battery minus the estimated 30%. In addition, there will be a 2500 charge cycle limitation throughout Tier 3. This clause means after 2500 charge cycles the battery is deemed to be at the end of normal life and has no replacement value.

Charger Warranty
Chargers, accessories, and any other MML products have a one-year factory defect non-transferable warranty. The Dynamic Charger has a 3 year full replacement warranty.

Prohibited Actions
Realize MML has a goal to supply quality products while being honest and transparent to their customers. MML expects the same type of courtesy and partnership from their customers. If products have been tampered with or altered, such actions will subject the product to a possible voided warranty. Some examples are, serial number tampering, label altering, unapproved modifications, or removal of codes and numbers.

Other Chargers
MML has spent extra time and effort designing chargers that charge, maintain, and bring lithium batteries out of protective modes. Unfortunately, the vast number of chargers on the market today do not have all these features and can result in a damaged battery. The most frequent neglect noticed is when lithium batteries go uncharged for long periods of time due to not having maintenance charging while the battery is in storage. Regularly MML has noticed that a small parasitic negative amperage draw is taking place when the battery is stored. This often is from items attached to the battery that requires power even when stored. Without the charger maintenance feature this can result in a damaged battery. If it is deemed that battery damage is a result of improper charging, battery warranty will be voided. MML is willing to repair the battery (if repairable) although the battery owner will be responsible for repair cost. Our advice is to make sure the battery is charged upon putting in storage and disconnect everything from the battery. Please charge the battery every 30-60 days to avoid potential warranty being voided.

Water Damage
Although MML prides itself on developing a robust and durable marine battery, we do not recommend submerging the battery under water, which can result in battery damage. If the battery is deemed to be defected due to water damage, warranty will be voided. MML is willing to repair the battery (if repairable) although the battery owner will be responsible for repair cost.

Eligible Warranty Locations
All Monster Marine Lithium Warranties are only available to the United States lower 48 states. If outside the lower 48 states, contact MML to discuss warranty options.

All Monster Marine Lithium Products have a non-transferable warranty.
Warranty only applies to the original purchaser and will not follow the battery when changing ownerships.

Monster Marine Lithium Batteries Inc. reserves the right to deny any warranty claim for any reason.

Batteries bought prior to the 15 year warranty change
For customers who have bought batteries prior to the 15 year warranty change and have the 5 year warranty do not worry warranty will transfer over. Please register your current batteries and chargers using the registration link by May 2024 to be eligible. If your battery or charger does not have a serial number please use the model number (MML-etc).

Shipping is typically through freight carriers and the actual shipping time is contingent on your location and the specific warehouse dispatching your order. Please allow for a 1-3 business day processing period before shipment, and an estimated delivery time of up to 7 business days. Your confirmation email will include delivery details and we will send you a tracking number as soon as one is available.
