Battery Testers & Hydrometers
Battery testers (including hydrometers) are devices for assessing batteries and accumulators in terms of voltage, charge state, internal resistance, capacity or acid density. They are used for maintenance, inspection, repair, quality control or lifecycle assessment of lead-acid, NiCd/NiMH, lithium or other battery types. With these devices the condition of a battery can be reliably evaluated and wear or faults detected early.
FAQ
What is a battery tester?
A battery tester is a device that evaluates batteries by measuring parameters like voltage, internal resistance, capacity, acid density (for lead-acid batteries) or general charge state.
Which battery types can be tested?
Depending on the tester, lead-acid batteries, sealed lead batteries, NiCd/NiMH rechargeable batteries, lithium batteries or maintenance-free batteries can be tested. Acid density measurement applies typically to lead-acid batteries.
Which parameters are commonly measured?
Typical parameters include resting or under-load voltage, internal resistance, remaining capacity, acid density (for lead-acid), charge level, and sometimes temperature or load performance.
Why is internal resistance measurement important?
Internal resistance indicates battery age, wear or internal faults. A high internal resistance often points to reduced performance, capacity loss or impending failure.
What does an acid density measurement indicate?
For lead-acid batteries, measuring acid density reveals the concentration and health of the electrolyte. Correct density indicates a fully charged, functioning battery; deviations hint at discharge, sulfation or cell damage.
When should batteries be tested?
Batteries should be tested before first use, after prolonged storage, after many charging/discharging cycles, before maintenance, after long idle periods or regularly as part of inspection routines (e.g. in UPS or backup systems).
How is a battery test carried out correctly?
Depending on test type: measure voltage at rest or under load; for internal resistance, apply defined load or use dedicated resistance test; for acid density only on de-energised battery; monitor temperature and state of charge.
What can distort battery test results?
Poor contacts, bad connections, temperature effects, deep discharge, incorrect test leads, acid stratification (in lead-acid), corrosion, or user errors can distort results.
How to interpret test results / when is a battery considered worn out?
If the voltage significantly drops under load, capacity is reduced, internal resistance is high or acid density is out of range (lead-acid), the battery is likely degraded or defective.
What safety measures are required when testing batteries?
Wear protective gloves and eyewear (especially for acid batteries), ensure good ventilation, avoid short circuits or sparks, disconnect battery if possible, and handle acid carefully. Use proper test leads and rated equipment.
How often should battery tests be done?
Depends on battery type and use: for regularly used or critical batteries (e.g. UPS, backup systems) at least annually, for others according to age, load cycles or storage conditions.
What are typical signs of battery failure?
Rapid discharge, persistent voltage drop, increased internal resistance, uneven cell voltages, overheating, poor capacity retention, acid leakage or corrosion (for lead-acid), irregular behaviour under load.
Can a battery be reused after testing?
If all test parameters are within acceptable limits and no mechanical or chemical damage is evident — yes. Otherwise repair (if possible) or replacement is recommended.
Which types of battery testers are available?
Basic voltage testers, digital battery testers with internal resistance measurement, hydrometers for acid batteries, load testers, capacity testers and combined multi-function battery analyzers.
How does temperature affect battery test results?
Low or high temperature affects voltage, internal resistance and electrolyte behaviour. Test results should be interpreted in consideration of ambient and battery temperature or standardized to reference temperature.
Is documentation of test results important?
Yes — especially for maintenance logs, warranty, facility management or safety-relevant installations. Document date, battery ID, test results and any measures taken for traceability.
What should be considered for batteries with long service life?
Track charge/discharge cycles, storage conditions, regular testing, avoid deep discharges, possibly equalize cells (for lead-acid) or replace weak cells to maintain overall performance and avoid unexpected failure.
