Battery Testing For Off-Grid Solar Products
Lighting Global has published Technical Note Issue 23, [Battery Testing for Off-grid Solar Products". The Note discusses issues related to the service life of batteries in solar products with a focus on Lighting Global`s battery testing policy. Battery failure mechanisms are briefly outlined along with a selection of battery testing procedures that Lighting Global has determined are cost effective and can be performed in a reasonable time frame. Justification is given for Lighting Global`s approach to battery testing, including a discussion of battery cycle tests that are not included in the Lighting Global program.
