Battery Ranges

Below we provide a quick overview on the batteries makes and types in this section. We can source a wide range of batteries. Please contact us if you cannot find the battery you need for your standby power application.

  • CSB Batteries: use VRLA lead acid technology and are suitable for security and fire panels, emergency lighting and uninterruptible power supplies.
  • GNP Sprinter series from Exide Technologies: VRLA lead acid batteries 10 year design life AGM batteries for UPS systems and DC standby power supplies.
  • Fiamm FLB, FGH and FGHL Batteries: use VRLA lead acid technology and for uninterruptible power supplies and DC standby power and backup systems.
  • Yuasa NP, NPL and Yucel series: VRLA lead lead batteries use oxygen recombination technology and are suitable for security and fire panels, emergency lighting and uninterruptible power supplies.
  • Yuasa SWL series: are VRLA lead acid batteries and an enhanced NP/NPL battery giving up to 40% more discharge capacity. They are ideal for high rate discharge applications including UPS systems and have a 10 year design life.
  • Yuasa EN Endurance series: VRLA lead acid batteries suitable for standby applications telecommunications, UPS and Emergency Lightning with a long design life (EN series: 10 years, ENL: 15 years)

If you are replacing a battery string we may be able to offer an extended warranty at no extra charge if you also install one of our battery monitoring solutions.

Battery Sizing

Batteries are sized based on their Ah (Ampere-Hour) and Vdc (voltage direct current). For the batteries on this page a 7-12 battery would have an Ah rating of 7Ah and a DC voltage of 12Vdc.

Often batteries are connected in series in strings to make a total Vdc battery string:

12Vdc+12Vdc+12Vdc=36Vdc

This 36Vdc battery string could support an inverter with a 36Vdc input requirement. The Ah of the battery defines how long the inverter could run for at a given load.

Using 7Ah in a 36Vdc battery string, a 36Vdc inverter may run for 6 minutes at 100% load or 8 minutes at 80% load (example figures).

If a longer runtime were required then two 36Vdc strings could be connected in parallel. The Vdc would still be 36Vdc but the battery set size would be 2×7=14Ah.

Please let us know if you require any assistance in sizing your batteries.
