NexSys ATEX batteries bring advantages of Thin Plate Pure Lead (TPPL) technology to materials handling vehicles operating in hazardous areas

NexSys ATEX batteries, available from EnerSys, allow materials handling vehicles to work safely in hazardous areas where there is an explosion risk. They conform to ATEX standards, which are compulsory and a legal requirement in Europe and NexSys batteries are also available world-wide certified in compliance with IECx standards. The new batteries, available in nearly all DIN sizes and capacities, offer significant advantages over both Valve Regulated Lead Acid (VRLA) gel and flooded lead-acid solutions. These advantages result from the Thin Plate Pure Lead (TPPL) technology used in the batteries' construction. Accordingly, they offer outstanding Amp-hour (Ah) capacity.

NexSys ATEX batteries require much lower maintenance than flooded types, with no need for topping-up. Critically for hazardous environments, the batteries' electrolytes are non-spillable, as they are absorbed into the Absorbent Glass Mat (AGM) separator material. They also recharge faster than gel and flooded batteries, with opportunity charging being possible. This increases productivity and reduces costs. Additionally, service life is longer than for gel batteries.


The battery products and process fulfil ATEX Directive 2014/34/EU, with the production process being externally audited at regular intervals to ATEX standards. The batteries are designed for use in ATEX Zones 1 and 2 (Gases) as well as 21 and 22 (Gas and Dust and Mining).


Each battery is engineered to specific customer requirements. These include specially designed trays and lids for Zone 1 and increased protection and testing for zone 21 and 22 batteries. While Zone 2 product does differ from standard batteries, lids are typically not fitted, as cover protection is usually provided by the equipment/application. Additionally, ATEX-certified plugs can be supplied and installed on request.


The batteries can be used over a temperature range of 0°C to 40°C, in low and normal duty applications working six days a week. Up to eight hours or more utilisation may be achieved, with a depth of discharge (DoD) to 80 per cent of C5, if recharge times are met. Cycle life can be improved by reducing DoD.


The batteries can be charged using NexSys or NexSys+, efficient modular high-frequency chargers. Charging time from 20 per cent state of charge to full charge is typically 6.25 hours or faster.
