The ACT CHROME 12V SLA Battery Tester uses advanced pulsed load technology to deliver accurate DC Voltage and Ah capacity results based on the battery’s temperature and state of charge. A quick look up table on the side of the unit identifies when batteries should be recharged or replaced due to age or operating conditions (65% of rated capacity). A temperature sensitive strip allows the ambient temperature to also be recorded.

The ACT CHROME 12V SLA Battery Tester offers a simple and accurate solution for testing 12V SLA batteries commonly used in fire, security and many other electrical systems.

• Many battery manufacturers rate their batteries at 20°C
• Below 20°C, the battery can have a significantly lower available capacity
• Over 20°C, the battery can have a significantly higher available capacity
• This can easily be as much as ±50% of the rated capacity
• Bear in mind the differences in temperature when testing – for example in an enclosure or next to a hot transformer (high than rated reading) or located externally / cold environment (lower than rated reading)
