As lead-acid looks to fend off the onslaught of lithium-ion, battery manufacturers are looking beyond SLI application to launch products into the datacenter and motive markets.
American firm EnerSys’ range of DataSafe XE batteries will outperform lithium-ion’s charging temperature range by using ‘Thin Plate Pure’ lead technology, enabling it to work from -40°C to 50°C.
The Absorbed Glass Mat (AGM) battery will also boast a 12 year design life at 25°C in the American, and 20°C in the EMEA and Asia markets.
The battery is designed to address lead-acid issues of corrosion of the lead grid in acid over time, and grid growth that results when batteries are exposed to high temperatures.
“Today’s batteries must break new ground. The batteries must be capable of providing more power at shorter run times and able to operate in higher ambient temperatures, while lasting longer,” said Dan Roche, marketing manager for UPS at EnerSys.
DataSafe XE batteries pack more plates into a two-volt cell, with each plate manufactured from high purity lead using a controlled fabrication process to reduce gas generation within the cell and extends the shelf life.
Meanwhile, lead-acid firm Exide Technologies’ new GNB® branded Tubular™ CMX™ and LMX battery line for motive power applications gives performances comparable to lithium-ion.
The CMX range is available in 85Ah and 125Ah versions and are designed to achieve 1,800 cycles at up to 80% depth-of-discharge.
The batteries are engineered for heavy-duty performance, with the round-tube technology providing lower internal resistances than competitive, square-tube designs.
