Battery capacity testing tool

The TES Electrical Electronic Corp. 33A is a handheld tester designed to measure battery capacity, internal resistance, and temperature. It provides direct current analysis for storage systems used in automotive and industrial maintenance. The unit arrives new in a single pack with a red finish.

Who this suits and who it does not

Technicians who need to verify battery health on-site will find the combined DCA, resistance, and temperature functions useful. Buyers who require data logging, wireless connectivity, or multi-cell balancing features should look at other instruments. The tester is limited to the measurements listed in the specifications.

Key measurement capability

The instrument performs three core tests: capacity, resistance, and temperature. This combination determines whether the tool matches the diagnostic routine required for the battery bank being serviced. No other measurement modes are included.

Questions about this item

Does the 33A tester need an external power source to operate?

The unit runs on its internal battery so no separate power supply is required for testing.

Can the 33A tester check older lead-acid batteries as well as newer chemistries?

It measures DCA, resistance and temperature on a wide range of lead-acid and compatible battery types.

How do I confirm the 33A tester is reading correctly after I connect the clamps?

A stable DCA value, low internal resistance and normal temperature reading indicate the tester is working properly.
