We find the SureStart Lithium DPX PR12-1400-GP31 a lightweight dual-purpose battery offering 1,400A rated cranking output and 80Ah of LiFePO₄ capacity. Its 12.8V system delivers 1,024Wh for starting and auxiliary loads, while the 7.6kg Group 31 case eases handling. Before buying, we’d verify engine starting demands, dimensions, terminal polarity, and lithium charging compatibility. It’s maintenance-free and suited to seasonal storage, but costs more than lead-acid. We’ll examine its features, trade-offs, and practical fit below.
Key Takeaways
- The SureStart Lithium DPX PR12-1400-GP31 is a 12.8V, 80Ah LiFePO₄ dual-purpose battery rated for 1,400A cranking output.
- Its 1,024Wh capacity supports starting and auxiliary power, but check engine requirements and household loads before buying.
- At 7.6kg, it is substantially lighter than comparable lead-acid batteries; confirm its Group 31 dimensions and Type A terminal layout fit.
- Sealed, maintenance-free construction, low self-discharge and UN38.3 testing suit seasonal storage, provided it is charged and disconnected appropriately.
- It costs more upfront than lead-acid, requires lithium-compatible charging, and includes a three-year warranty with UK technical support.
1,400A Cranking Output
When the engine needs to turn over, the SureStart delivers a manufacturer-rated 1,400A cranking output. That rating supports petrol and diesel engines, including outboards, inboards and commercial plant. For you, the practical question is whether the battery suits your engine’s starting requirements; check its specification before installation.
The 12.8V LiFePO₄ design combines engine starting with domestic and auxiliary power, so we can use one battery for multiple onboard needs. Strong cranking output contributes to Starting reliability, while actual Cranking performance depends on engine condition, temperature and installation. We shouldn’t treat the rated figure as a guarantee of starting in every operating condition.
Detailed features
Beyond its 1,400A cranking output, the SureStart combines an 80Ah capacity with a compact, lightweight design. Its LiFePO₄ Battery chemistry delivers 12.8V nominal voltage and 1,024Wh of energy for starting and auxiliary loads.
At 7.6kg, it weighs substantially less than a comparable lead-acid battery. The Group 31 case measures 330 × 180 × 224mm and includes a webbing carry handle.
Before fitting, check installation requirements: confirm the dimensions, terminal type A, and left-side positive polarity match your existing setup. The sealed, maintenance-free construction needs no topping up, contains no free acid, and has passed UN38.3 testing for transport safety.
Pros and Cons
We’ll weigh the PR12-1400-GP31’s key advantages, including its 1,400A starting output, 80Ah capacity and low 7.6kg weight.
We’ll also consider trade-offs, such as its Group 31 fit requirements and the need to verify terminal layout and polarity before installation. This comparison will help you judge whether it suits your application.
Pros
The SureStart Lithium DPX PR12-1400-GP31 combines 1,400A manufacturer-rated cranking output with 80Ah (1,024Wh) of auxiliary capacity, so one battery can support both engine starting and onboard loads. Its LiFePO₄ chemistry delivers usable energy deeper into discharge than comparable lead-acid or AGM batteries, helping us power equipment efficiently.
At 7.6kg, it offers substantial Reduced battery weight versus an 80Ah lead-acid equivalent, simplifying handling and installation. Very low self-discharge also makes seasonal storage practical: we can charge the battery fully, disconnect it, then reconnect it when needed. The sealed, maintenance-free design requires no topping-up and prevents acid spills.
Cons
Those advantages come with fit and cost considerations: at 330 × 180 × 224mm, the Group 31 case may not suit every battery compartment, and its Type A terminals place the positive post on the left. We should check dimensions, terminal type and polarity before buying, since limited compatibility can require installation changes or rule out a direct replacement.
High upfront cost is another drawback: lithium batteries typically demand a larger initial investment than lead-acid alternatives, even when their lower weight and deeper usable capacity offer practical benefits. At 7.6kg, this model is easy to handle, but its 80Ah capacity may not meet every high-demand setup.
Concluding thoughts
For a build that needs both reliable starting power and usable auxiliary capacity, the SureStart Lithium DPX PR12-1400-GP31 offers a compact, lightweight option. Its 80Ah LiFePO₄ capacity, 1,400A rated cranking output and 7.6kg weight suit vehicles, boats and off-grid systems where space and payload matter.
Before buying, we’d verify Group 31 dimensions, terminal type and left-side positive polarity against the installation. The three-year warranty and UK technical support add reassurance, but don’t guarantee long term reliability.
We’d consider the ideal ownership profile a user who values reduced weight, low self-discharge and dual-purpose power, and can meet lithium charging requirements.
Frequently Asked Questions
Is the Surestart Lithium DPX Compatible With My Existing Charger?
We can’t confirm compatibility without your charger’s specifications. Check Charger voltage compatibility: it must suit a 12.8V LiFePO₄ battery. Verify Charging profile requirements; use a lithium-compatible profile, not lead-acid equalisation, and consult your charger manufacturer.
Can I Connect It in Parallel With Another Battery?
Yes—we can parallel it, building a battery bank sizing plan that won’t launch your setup into orbit. For parallel wiring safety, use matching 12.8V LiFePO₄ batteries, equal cable lengths, and manufacturer-approved connections.
What Should I Check Before Replacing My Current Battery?
Before replacing your battery, we should verify the battery compartment accommodates the 330 × 180 × 224mm Group 31 case, then confirm terminal type, left-side positive polarity, voltage, and power requirements match your installation.
How Should I Store the Battery During the Off-Season?
Lo, store it charged: we should disconnect loads, protect terminals, choose a cool location, avoid freezing temperatures, prevent moisture exposure, inspect periodically, maintain charge level, follow manufacturer guidance, and prepare for reinstallation.
What Support and Warranty Are Included With the Battery?
Warranty coverage includes three years from Predator Batteries Ltd. We can direct you to the manufacturer’s UK-based technical support for product assistance. Your battery also includes a user manual for installation and operation guidance.
Conclusion
We see the Predator SureStart Lithium DPX PR12-1400-GP31 as a compelling dual-purpose battery for builds that need strong starting power and usable auxiliary capacity. Its 1,400A cranking rating, 1,024Wh storage and 7.6kg weight make a persuasive combination, provided its Group 31 dimensions and left-hand positive terminal suit your installation. The three-year warranty adds reassurance, though we’d confirm compatibility and charging requirements before purchase. For the right setup, it can be a lighter heart for your power system.
