Our Battery Lifespan & Diagnostic Services

1. Battery End-of-life Prediction Services

Your product quality, and therefore your customers satisfaction, depends on the battery you choose. The vast array of technologies, suppliers and prices only makes the selection of the right battery harder.

The choice of a battery should never rely on the sole analysis of the manufacturers datasheet. The field conditions – like application consumption and operation temperature – will influence the lifespan and autonomy of your batteries and make it diverge from the datasheet.

At Enerstone, battery lifespan is our core competency. Our experts help you evaluate the end-of-life of a battery in the conditions of your application. Because customer satisfaction cannot be left to jeopardy, let us guide you in the selection of the battery that fits your specs.

2. Battery Diagnostic and Post-Mortem Analysis

You are experiencing battery failure

We realize a complete root-cause analysis that specify the nature, location and cause of the anomaly.

Your battery does not hold the charge

We realize a state-of-health diagnostic of your battery and evaluate the possibility to replenish its capacity or change damaged battery cells.

Experts in battery design and analysis, we are qualified to identify the root cause of the battery failure.

In the context of evolving IATA regulation on air transportation of lithium batteries, we are your European expertise to realise the post-mortem analysis of damaged batteries. Conveniently located in the Rhone-Alpes region, Enerstone brings you the reactivity and confidentiality to perform all types of post-mortem analysis.

Contact us today for details on submitting a battery for diagnostic or post-mortem analysis.
