Product Warranty

PowerHouse Lithium Warranty

Important Information: Battery Service and Inspection

 Please be aware that if your battery needs to be sent for inspection, you may be responsible for a repair and shipping fee of up to $150. This fee covers both the repair and the shipment of the product. These costs apply if the issue is a result of user error or misuse, and therefore not covered under our standard warranty.

Examples of issues caused by user error or misuse include:
 * Dead battery: This can be a result of improper charging, not charging a fully drained battery, or loss of Bluetooth connection in the app.
 * Physical damage: Examples include over-tightening the battery strap, loose connections causing the battery terminals to melt, or over-tightening the terminal bolts.
 * Short cycle counts.

If the inspection determines the issue is due to a manufacturing defect, the standard warranty process will be followed, and you will not be charged.

WARRANTY REGISTRATION

We recommend you protect your investment and register your warranty. If your battery is not registered within 90 days of purchase, warranty will begin at manufacture date of battery. Proof of ownership is required. Warranties are not transferrable. 

WARRANTY FEES FOR DEEP CYCLE 40AH +(Non-Cranking)  BATTERIES

CRANKING AND 48V BATTERIES CARRY A 5 YEAR FREE REPLACEMENT WARRANTY*

  • 15 years total**
  • 10 years non-prorated** 
  • Replace defective battery for free any time inside of 60 months.
  • Repair battery for free from year 5 through year 10
  • Customer will have option for expedited replacement battery year 5 through 10 with immediate battery replacement for 30% off of MSRP. This will forego the 2 to 6 week turnaround time on battery repair. Plus give you new battery with new 15 year warranty.
  • All warrantied items will be subject to the shipping cost from PowerHouse Lithium of $60. This fee is waived for the first year only no exceptions.
  • Warrantied replacement cost is based on current MSRP on all batteries over the 5 year period. 

Replacement cost of batteries over 10 years old that have a 15 year warranty will be sold at 30% off MSRP, for customer satisfaction of being a loyal customer to the brand.

* Batteries with more than 2,000 cycles are considered at the end of normal use. For those batteries, being a Powerhouse customer. We will offer a discounted price of 10% off retail for a new battery. 

Example of how long 1000, 1500 and 2000 cycles would be.

1. You fish 2 times a week every week and you need to charge every time (most cases you will not) but just for example purposes. 2 x 52 = 104 cycles per year divided into 1000 cycles is 9.62 years. 

2. Same setup but now 1500 cycles

104 cycles per year divided into 1500 cycles is 14.42 years 

3. Same setup but now 2000 cycles (the average life for a LiFePo4 Battery)

104 cycles per year divided into 2000 cycles is 19.23 years 

 Don't be mislead about companies that advertise their batteries that do 5000 cycles as all LifePO4 batteries with Grade A cells are the same. Sure, our batteries will do 5000 cycles as well but what they fail to tell you is that is with only 10% usage in the battery each cycle. 

The fact about Lithium is that it only has so much total energy in it's lifetime that it can be transferred back and forth so the deeper the charge the less cycles it will go, and the quick charge of 20% or less it will go a lot longer. The end result no matter how you want to charge your batteries the total amount of energy will be the same at the end of the batteries life.
