12V 40Ah 1,400 Cranking Amp Lithium Battery: Your Reliable Lithium Starting Battery

The 12V 40Ah is one of the most powerful lithium cranking batteries on the market, capable of taking on some of the bigger boats. Engines up to 450hp are no sweat. It’s solid, safe, and simple to monitor your battery via Bluetooth.

But surely there’s a “catch,” right? No battery could be this good. There must be some downside, like bulky sizing or back-breaking weight. Not the case with this battery. Forget finding a catch – this is the catch.

Only the Best Battery for Your Boat: 12V 40Ah Lithium Battery Uses

Your cranking battery is what brings your boat to life. Without a battery, it’s just a dust-collecting dock decoration.

But not just any battery will do. You need one that won’t weigh down your boat, doesn’t require maintenance, and effortlessly fires up your engine. Good news: you’ve found it.

For offshore and center console boats, our 12V 40Ah battery is the ideal starting battery. Like all of our marine batteries, it charges five times faster than lead acid and maintains that charge for much longer than other battery types.

Bigger Isn’t Always Better: Battery Features

Think a hefty battery equals a better battery? Think again. Weighing in at just 14.6 lbs, this lithium cranking battery is remarkably lightweight for the amount of power it delivers.

That’s incredible, especially considering that lead acid 12V 40Ah batteries weigh at least double. Switching to lithium is an easy way to cut down on weight (which saves money on gas!) and minimize the space you’re using in your center console boat. It also saves your back from lugging around a 26-pound traditional lead acid battery.

But back-saving isn’t the only superpower of this power pusher. Our lithium cranking battery also cranks out anxiety-busting safety features such as:

• An integrated, microprocessor-controlled battery management system (BMS).
• The microprocessor monitors main operating parameters while safely charging and discharging (voltage, currents, internal temperatures, etc.)
• Smart capabilities prevent overcharging or charging when temperatures are too low. This helps prevent damage to your battery.
• Bluetooth function: connect your battery to your smartphone wirelessly and view data like battery status and charge left.
• Emergency start mechanism (see details below)

State-of-the-Art Safety: Emergency Start Feature

Ever been stranded at sea with a cranking battery that won’t start? Here’s to hoping you never experience such bad luck. You don’t have to leave it to luck. With a smart lithium cranking battery, you can make sure your engine starts every time.

The unique emergency start function saves 25% of the battery reserve for emergency start purposes. To start your engine up in an emergency, just reactivate the battery with the Ionic App on your phone or long-press the battery’s emergency start button.

12V 40Ah Lithium Battery: How Does it Compare to Other Battery Types?

When you invest in a new battery, you want one that lasts. Not one that has to be replaced just a few years later. All those replacements add up, even if they aren’t costly upfront. You’ll end up spending more money in the long run.

Maybe it’s time to choose quality over “cheap”. Our 12V 40Ah lithium battery is built to outlast the competition but comes at a competitive price. With a cycle life of 3,000 to 5,000 cycles, it’ll last roughly 10 years depending upon usage. Think about it – that could mean 10 whole years without having to replace your battery.

But that’s not the only reason why our 12V 40Ah lithium cranking battery comes out on top. Other battery types just can’t provide the same amount of efficiency. For example, lithium batteries have a 99% usable capacity. You can spend all day out on the water and not even come close to draining your battery. How much usable capacity does lead acid offer? A measly 50-60%. See all lithium marine batteries here.
