Q 1. What is the voltage and capacity of the Lucas LSLA2.3-12?

A. The Lucas LSLA2.3-12 is a 12-volt battery with a rated capacity of 2.3Ah (C20). It is designed for standby and small mobility applications rather than engine starting.

Q 2. What battery technology does the LSLA2.3-12 use?

A. It uses absorbed glass mat (AGM) technology, in which the electrolyte is held within a fibreglass separator. This produces a sealed, valve-regulated, maintenance-free battery that can be installed in any orientation.

Q 3. What are the physical dimensions and weight of this battery?

A. The LSLA2.3-12 measures 178mm in length, 34mm in width, and 64mm in height including the terminal. It weighs 0.97 kg.

Q 4. What terminal type does the LSLA2.3-12 use, and what is the polarity designation?

A. The battery is fitted with spade tab (TAB) terminals. The polarity designation is 3. The hold-down type is B00.

Q 5. Which competitor part numbers does the LSLA2.3-12 replace or cross-reference?

A. The LSLA2.3-12 cross-references to NP2.3-12 and NP2.1-12, making it a suitable replacement for batteries carrying those part numbers. Always verify fitment against your application's specification before installation.

Q 6. Is the LSLA2.3-12 suitable for use in alarm systems and emergency lighting?

A. Yes. As an AGM standby battery it is well suited to float-charge applications including intruder alarm panels, emergency lighting units, and small UPS systems, provided the equipment's charge voltage and current requirements are compatible.

Q 7. Does this battery support start-stop vehicle systems?

A. The AGM technology used in this battery is inherently compatible with start-stop operation. However, suitability for a specific vehicle must be verified against the product label and the vehicle manufacturer's specification. This battery is primarily rated for standby use at 2.3Ah and is not a cranking battery.

Q 8. Are Cold Cranking Amps (CCA), MCA, or Watt-Hour ratings published for this battery?

A. Cold Cranking Amps, Marine Cranking Amps, and Watt-Hour figures are not published for the LSLA2.3-12, as it is specified for standby and mobility applications rather than engine cranking duty. Capacity is rated at 2.3Ah (C20).

Q 9. What warranty does the Lucas LSLA2.3-12 carry, and what other capacities are available in this range?

A. The LSLA2.3-12 is covered by a 1-year warranty against manufacturing defects. Other capacities available in the Lucas Supreme AGM standby range include 1.2Ah, 4Ah (6V), 5Ah, 7Ah, 9Ah, 10Ah, 12Ah (12V and 6V), 14Ah, and 20Ah variants.
