iv. where there is no evidence of abuse, misuse, negligence or modification; 
v. where the battery has been recharged within the recharge period stated on the packaging;
vi. where average battery temperature is less than 40°C over the functional life of the battery(noting the battery module records and averages the temperature daily and is stored on the individual battery log);
vii. where the battery temperature does not exceed 50°C; 
viii. where the battery charge voltage never exceeds 57.4 Vdc; 
ix. where the battery voltage never falls below 43.4Vdc;

Battery Warranted Performance

1.The following table outlines the minimum energy throughput based on average cell temperature or 10 Years, whichever occurs first:

 Average Cell Operating Temperature (C) at 80% D.O.D
Model< 25C< 30C< 35C< 40C
Guardian LFPro 2049.2 MWh38.4 MWh30.4 MWh24.8 MWh
Guardian LFPro 2561.5 MWh48 MWh38 MWh31 MWh
Guardian2661.6 MWh49.8 MWh38 MWh34.1 MWh
Guardian3892.4 MWh74.7 MWh57 MWh47.1 MWh
Guardian50123.2 MWh99.6 MWh76 MWh62.8 MWh


2. Average temperature is the average temperature measured in Degree Celsius (°C). The temperature of the internal battery module(s) is recorded at one minute intervals and averaged over the day. The average temperature over the lifetime of the battery system is calculated by adding all the average daily temperatures and dividing the sum by the number of days of operation.

3. A battery module is determined to be defective if the module fails to deliver more than 60% of its original capacity.

4. In the case a battery module is deemed to be faulty and requires repair or replacement, the replacement battery module will feature an equal or greater remaining energy throughput (Ah) than the replaced battery module.
