We have a complete Victron unit with solar panels and lead acid batteries ( we are off grid) The first set of batteries( lead acid) lasted 6 years before voltage failure in two batteries , so we replaced all four with Victron lead acid batteries guaranted for two years. After 18 months one battery failed going from 12v to 9 v storage in à week thé supplier and Victron are refusing to honour the warranty . Is this common practice in the industry? ---

The warranty is limited, so there are exclusions. Installation issues or charging/discharging incorrectly would void the warranty. You would need to be able to show that it was a genuine fault vs installation/configuration/use. ---

Because we are off grid we do not have a wired internet connection but we have the Victron app on our phones showing the batteries have been correctly charged and never deep discharged. ---

It’s difficult over the internet to comment apart from confirming it is a limited warranty ([you can download it](https://www.victronenergy.com/upload/documents/Victron-Energy-Limited-Warranty-Policy-2025-(P).pdf)). The supplier would need to provide a justification why warranty is being declined. > **Warranty** > > 2 years from date of purchase by the original end-user, with a maximum of 30 months from the Victron Energy > > invoice date, Lithium batteries: 3 years from date of purchase by the original end-user, with a maximum of 42 months from the > > Victron Energy invoice date. In addition to this, proof of correct battery usage is required when making a battery warranty claim. If the batteries are very old stock, you may fall outside of the warranty period. ---

That’s why we stopped selling lead batteries 7 or 8 years ago. The quality was dropping dramatically (across different manufacturers). ---

The race to the bottom is a real thing. ---

It is common practice in the world I’m afraid, but in this case how on earth would you prove compliance, installation by approved installer / non stop data logs / tamper proofing of installation and parameters that may be required if going legal. Read the small print of any guarantee / insurance and good luck complying / proving all of it. As an example, i was watching congressional hearings the other day on USA house insurance and oh boy what a scam. ---

Victron also specifies that the life of batteries depends on their cycling, which can range from 500 to 1800 cycles, or less than a year and a half to 5 years. Victron is this correct for lead acid batteries?
