About Your SOLAR Battery Tester (Model BA5) or
SOLAR Battery and System Tester (Model No. BA7)
Battery Tester Models BA5 and BA7 are designed to test only 12 Volt batteries and
systems (BA7 only). The testers are compatible with a wide range of battery types,
including Conventional, Maintenance Free, AGM, Gel Cell, Marine and Deep Cycle
batteries. The testers can test these types of batteries against several battery
capacity rating systems. Below is a chart of the operating range of the testers
based on the applicable capacity rating systems:
Rating System Testing Capacity
CCA 100-1200 CCA
DIN 55-670 CCA
IEC 65-790 CCA
EN 95-1125 CCA
CA(MCA) 120-1440 CA(MCA)
The testers have a recommended operating ambient temperature range of 32˚F to
122˚F.
Preparing Battery to Be Tested
1. Be sure area around battery is well ventilated while battery is being tested.
2. Clean battery terminals. Wire brush them if necessary. Be careful to keep
corrosion from coming in contact with eyes.
3. Inspect the battery for cracked or broken case or cover. If the battery is
damaged, do not use tester.
4. If the battery is not a sealed Maintenance Free battery, add distilled water in
each cell until battery acid reaches level specified by the manufacturer. This
helps purge excessive gas from cells. Be careful not to overfill.
5. Confirm that all vehicle accessories are turned OFF to ensure you do not cause
any arcing and that the tested battery has a nominal voltage of 12 Volts.
6. If it is necessary to remove battery from vehicle to test, always remove ground
terminal from battery first.
