📏 BUILT FOR NARROW INSTALLATION SPACES

One of the major advantages of the Predator FTG12-150 is its narrow 110mm case width.

With overall dimensions of approximately 551mm long × 110mm wide × 288mm high, the FTG12-150 is designed to provide substantial deep cycle capacity while occupying considerably less installation width than many conventional-format high-capacity batteries.

This narrow configuration can make the FTG12-150 particularly useful where a battery needs to be positioned beside equipment, within a custom battery compartment or in another restricted-width installation.

⚠️ IMPORTANT: The FTG12-150 is narrow but is also approximately 551mm long, 288mm high and 46.4kg. Always physically measure the installation location and confirm mounting strength before purchase.

---

🔋 TRUE DEEP CYCLE GEL CONSTRUCTION

The Predator FTG series is specifically designed for deep cycle applications.

Unlike a starting battery that is primarily designed to provide short bursts of high cranking current, the FTG12-150 is designed to provide stored energy over longer periods before being recharged.

This makes it suitable for compatible auxiliary electrical systems where appliances and equipment regularly draw power from the battery.

⚠️ IMPORTANT: Deep cycle construction does not mean the battery should routinely be discharged completely. Battery service life is strongly influenced by depth of discharge, charging quality, operating temperature and how promptly the battery is recharged after use.

---

🧪 GEL BATTERY TECHNOLOGY

The Predator FTG12-150 uses Gel battery technology rather than AGM construction.

The electrolyte is immobilised within the Gel battery design, helping provide spill-resistant operation and eliminating electrolyte stratification.

Gel technology also provides excellent deep cycle characteristics and high thermal stability for compatible auxiliary and stored-energy applications.

⚠️ IMPORTANT: GEL and AGM are both sealed lead-acid battery technologies, but their recommended charging voltages can differ. Use charging equipment suitable for GEL batteries and follow the FTG12-150 charging specifications.

---

🧱 LEAD-CALCIUM ALLOY GRIDS

The Predator FTG series uses lead-calcium alloy grids designed to reduce corrosion and support extended battery cycle life.

This construction contributes to the FTG12-150’s suitability for repeated deep cycle operation and long-term auxiliary-power applications.

---

💨 ONE-WAY VENT VALVE

The FTG-series battery design incorporates a unique one-way vent valve.

This valve is designed to control internal gassing and minimise water loss, helping provide true maintenance-free operation.

There is no routine requirement to check or top up electrolyte as with a conventional serviceable flooded lead-acid battery.

---

---

☀️ SOLAR CHARGING APPLICATIONS

The FTG12-150 can be used with a compatible solar charging system where the regulator supports GEL battery charging.

The charging system should be configured within the supplied bulk-charge range of 14.1V–14.4V at 25°C and remain within the supplied maximum charge-current limit of 37.5A.

⚠️ IMPORTANT: Check the solar regulator’s actual GEL charging profile rather than relying only on a generic “lead acid” setting.

---

⚡ UPS & STANDBY POWER

UPS and standby-power systems are specifically listed among the intended applications for the FTG12-150.

Its 13.5V–13.8V standby / float voltage specification allows it to be maintained by compatible regulated standby charging equipment.

Always confirm the voltage, capacity, physical dimensions, terminal configuration and charging requirements specified by the UPS or standby-power equipment manufacturer.

---

⚡ INVERTER APPLICATIONS

The FTG12-150 may be used with a compatible inverter where the battery capacity, inverter power, cabling and circuit protection are appropriately designed.

High-power 240V appliances can result in substantial current draw from a 12V battery, so battery capacity alone should not be used to determine inverter suitability.

⚠️ IMPORTANT: Consider inverter continuous power, surge requirements, DC current, cable length, voltage drop, fuse or circuit-breaker rating and allowable battery depth of discharge when designing an inverter system.

---

📉 LOW SELF-DISCHARGE

Supplied self-discharge:

≤3% per month

The low self-discharge characteristic helps the FTG12-150 retain charge during periods when the battery is not actively being used.
