Quick Tips!

<div style="text-align: center;" Hawker^® has a new look and a new location! Check us out at www.hawkerbattery.com. Say goodbye to zoom, the site features device scaling. So, the information you need just got easier to find whether using a computer, tablet, or smartphone!

Answer to question from last issue:

My Hawker^® battery passed testing, so can it be mixed with other Hawker^® batteries that are the same model?

That depends. As batteries age, they develop significantly different capabilities (usually, the result of plate sulfation). So…when mixing batteries in parallel, series, or series-parallel configuration…

1. Open Circuit Voltage (OCV) Test: &nbsp ensure all fully-charged batteries are within a 0.15 volt OCV range of each other (e.g., if the highest battery measures 12.9 volts OCV (no load), then the lowest battery should measure no less than 12.75 volts OCV.), and

2. Conductance Analyzer Test: &nbsp ensure all fully-charged batteries are within a 10% CCA range of each other (e.g., if the highest battery measures 1225 CCAs, then the lowest battery should measure no less than 1102.5 CCAs), or

3. Mechanic’s Load Test: &nbsp ensure all fully-charged batteries are within a 0.4 volt CCV range of each other (e.g., if the highest battery measures 11.2 volts CCV (load voltage), then the lowest battery should measure no less than 10.8 volts CCV), or

4. Capacity Test: &nbsp ensure all fully-charged batteries are within a 10% Ah range of each other when discharged at a specified C-rate (e.g., if the highest Capacity battery measures 120 Ah (C20), then all batteries should be within 12 Ah range of each other, so the lowest Capacity battery should measure no less than 108 Ah (C20). Note: This test is normally only conducted by design engineers.

Did you know?

With the migration to www.hawkerbattery.com, that the free Hawker^® Helpdesk video training series is now located in the Video Vault section.

Oh, and the videos are still available on YouTube.com
