The DELTABAT® 30 battery capacity tester supports a voltage range of 1V to 30V and is compatible with acid (AGM, gel, SLI), lithium (including LiFePO₄), nickel-cadmium and sodium-ion batteries. Importantly, the device’s design allows for safe and reproducible use, even under intensive workshop conditions.
What can I use the DELTABAT® unloader for?
- Warranty and post-warranty verification of batteries.
Customer reports problems with starting the vehicle engine. Although standard diagnostics (DBT-12+, BLT-600S) does not reveal significant abnormalities, only a full capacity test with DELTABAT® reveals significant degradation – the battery from the declared capacity actually has only a fraction of it, which, combined with frequent starts and short distances covered, generates a problem – the car does not start. - Practical test of energy storage and UPS – In a direct way, we get the answer to the question of how long we can use the stored energy in the UPS by powering selected loads. It is enough that we know the consumed power in Watts.
- Quality control of deliveries. The importer receives a sample batch of batteries. With DELTABAT® , it is possible to objectively verify compliance with the declared capacity. Differences between nominal and actual values provide the basis for an informed purchasing decision.
