The weight thresholds matter. A portable battery is sealed, 5 kg or less, not specifically designed for industrial use, and not an EV, LMT, or SLI battery. An LMT battery is sealed, 25 kg or less, and specifically designed for traction in light means of transport. An EV battery is specifically designed for traction in category L vehicles when it weighs more than 25 kg or for category M, N, or O vehicles. An industrial battery covers batteries specifically designed for industrial uses, repurposed batteries intended for industrial uses, and any other battery weighing more than 5 kg that does not fit EV, LMT, or SLI.
Do not use marketing language alone. Use the legal definition plus the actual intended use. For example, a domestic storage battery can still be an industrial battery for the Regulation.
