We find the SFL 110AHC100 a practical 12V leisure battery, with 110Ah capacity measured at the C20 rate under EN50342-1 conditions. Its sealed, maintenance-free lead-acid construction suits caravans, motorhomes, boats, and off-grid systems, while the separate 130Ah figure reflects a 100-hour discharge test. The built-in flame arrestor and charge indicator add useful features. Before buying, we’d check the 18kg weight, left-positive terminal layout, case clearance, and two-year warranty against your installation needs; our review covers these trade-offs in detail.
Key Takeaways
- The SFL 110AHC100 is a 12V deep-cycle battery rated at 110Ah under C20 testing.
- Its manufacturer also lists 130Ah at a 100-hour discharge rate; the figures use different test durations.
- Sealed, maintenance-free construction includes a flame arrestor and state-of-charge indicator.
- It suits leisure, solar, and backup systems, but actual runtime depends on load and operating conditions.
- Check the 315 × 175 × 175 mm case, left-positive T1 terminals, and installation clearance; it weighs 18kg and has a two-year warranty.
110Ah Deep-Cycle Capacity
The SFL 110AHC100 provides 110Ah of deep-cycle capacity, measured at the C20 rate under EN50342-1 testing conditions. This C20 capacity rating gives us a standard basis for comparing usable charge with other leisure batteries.
The manufacturer also states a 130Ah 100 hour capacity, reflecting the greater measured output when discharge occurs over a longer period. These figures describe capacity under different test durations, not a contradiction.
For your 12V caravan, campervan, motorhome, boat, solar setup, or backup system, they help us assess how the battery may support sustained loads. Actual runtime depends on appliance demand and operating conditions.
Detailed features
Beyond its capacity ratings, the SFL 110AHC100 includes practical safety and handling features: a sealed, maintenance-free lead-acid design, a dual lid with a built-in flame arrestor, a carrying handle, and a state-of-charge indicator. This Sealed construction prevents spills during normal use and eliminates water refills.
We can check the charge indicator to assess the battery’s state of charge without adding a separate monitoring device. The flame arrestor helps contain ignition risks, while the handle supports lifting and positioning its 18 kg body.
Remove the red transport bungs immediately upon receipt to help prevent damage. Its 315 × 175 × 175 mm case includes terminals.
Pros and Cons
We’ll weigh the SFL 110AHC100’s 110Ah C20 capacity, maintenance-free sealed construction, and safety features against its 18kg weight and lead-acid chemistry.
We’ll also consider its 130Ah rating at a 100-hour discharge rate and 2-year warranty. This comparison will help you assess its suitability for your setup.
Pros
For off-grid use, the SFL 110AHC100 combines a 110Ah C20-rated capacity with a maintenance-free, sealed design suited to regular deep-discharge and recharge cycles. Its 12V output supports common leisure systems, while the stated 130Ah capacity at a 100-hour discharge rate can suit low, steady loads.
For Off Grid Reliability, we value the sealed, spill-proof construction, state-of-charge indicator, and two-year warranty. Caravan Compatibility benefits from its standard T1 terminals, universal fit, and compact 315 × 175 × 175 mm dimensions. The carrying handle aids installation, and the dual lid with flame arrestor adds practical safety features for mobile power applications.
Cons
Although the SFL 110AHC100 offers useful off-grid capacity, its 18 kg weight and 315 × 175 × 175 mm dimensions may limit installation options in tight spaces. This Heavy weight can also make lifting and securing the battery harder, especially in cramped caravan or boat compartments.
We should check tray dimensions, terminal clearance, and mounting access before purchase. Its lead-acid chemistry is heavier than many lithium alternatives and may provide less usable energy at comparable nominal capacity.
The Limited warranty lasts two years, which may feel brief for a battery expected to handle regular deep-discharge cycles. No accessories are included, so installation hardware may require separate purchase.
Concluding thoughts
Overall, the SFL 110AHC100 is a practical choice for leisure and off-grid systems that need a sealed 12V deep-cycle battery. Its 110Ah C20 rating, maintenance-free construction, and spill-proof case suit caravans, boats, and backup use. For Everyday reliability, remove the red transport bungs on receipt and confirm the 315 × 175 × 175 mm footprint and left-positive terminals fit your installation.
| Factor | Specification | Consideration |
|---|---|---|
| Capacity | 110Ah C20 | Deep-cycle use |
| Safety | Sealed, spill-proof | No water refills |
| Support | Two-year warranty | Check fit first |
We’d weigh its 18kg mass and lead-acid chemistry against long term value, choosing it when compatible charging and straightforward 12V power matter most.
Frequently Asked Questions
Which Charger Is Suitable for the SFL 110AHC100?
Choose a smart charger designed for sealed 12V lead-acid batteries. Match Charger voltage to 12V, and select Charging current around 11A, roughly one-tenth of the battery’s 110Ah capacity; follow charger manufacturer guidance.
Can This Battery Be Installed Inside a Caravan?
Yes, we can install it inside a caravan, provided we follow battery ventilation requirements. Better safe than sorry: secure the sealed, spill-proof battery upright in a ventilated compartment, away from ignition sources, and follow manufacturer guidance.
How Should the Battery Be Stored When Not in Use?
Store the battery disconnected in Cool dry storage, upright and away from heat or sparks. We recommend periodic voltage checks; recharge it if voltage falls, and remove the red transport bungs before use.
What Should I Do With the Red Transport Bungs?
Remove the red transport bungs immediately upon receipt; don’t let them linger. For bung removal, we should pull both bungs out before using the battery, helping prevent damage and supporting safe, reliable operation.
Is This Battery Compatible With Solar Charge Controllers?
Yes, we can use this 12V lead-acid battery with a compatible solar charge controller. Set Controller settings for sealed lead-acid chemistry, 12V, and manufacturer-recommended charging voltages; verify compatibility before Solar charging to prevent overcharging.
Conclusion
We see the SFL 110AHC100 as a practical 12V leisure battery for regular caravan, campervan, boat, and backup use. Its 110Ah C20 rating, sealed construction, charge indicator, and 800A EN starting capability offer useful versatility, while its 18kg weight and 315 × 175 × 175mm case make fit checks essential. Remove the red transport bungs after delivery, and confirm the left-hand positive T1 terminal suits your setup. Think of it as a dependable workhorse, not a magic lantern.
