Product Description

12V 9Ah Starter Battery: Lasting Power

lifepo4 12v 9ah battery | starter batteryOur 12V 9Ah battery is perfect for starting zero-turn mowers (above 21hp) and Side-by-Sides/UTVs. They’re lightweight, energy efficient, and offer Bluetooth monitoring at all times.

Without the use of a trickle charger, most lead acid starter batteries go bad after the mowing season is over. Why? Because they simply drain too low. What’s the use of a battery if it has to be replaced year after year? With a dependable LiFePO4 starter battery you’ll no longer face these issues. One of the most celebrated benefits of our starter batteries is that they’ll turn off with 25% capacity remaining, instead of no longer being usable.

So whether you’re using our 12V 9Ah battery in a mower or a UTV, you don’t have to worry if you accidentally run it too low. With our built-in Emergency Start function, you can simply press a button and get things fired up again in an instant. All thanks to the emergency start and your battery reserve. Easy peasy.

Impressive Safety Features

First off all, Ionic batteries are rigorously tested in-house, and only contain Grade A battery cells.

Second, each and every battery from LithiumHub comes with a built-in Battery Management System (BMS). This advanced system monitors the battery’s voltage, currents, and temperature at all times. If the temperature is too hot or cold, these “smart batteries” won’t accept the charge. This means your battery will last longer and you won’t face damage from voltage issues or the circuit shorting out.

And with the use of the Ionic App you’ll have immediate access to your battery’s juicy details at all times. Who wants their lawn mower to die and fail to start, mid-job? Or their UTV to stop blazing trails and fail to start, miles and miles away from home? As much of an inconvenience either scenario may be, it can also be a safety issue. So before you set out, check the status of your 12V 9Ah battery via the Ionic App. There you can check the status of your charge, voltage, current, discharge, temperature, and more. You’ll be in the know at all times! So whether you’re a homeowner or a business owner, there are plenty of benefits of powering up your lawn mower or UTV/Side-by-Side with a trusted LiFePO4 12V 9Ah battery from LithiumHub.

They Simply Last Longer..

lifepo4 12v 9ah battery | starter battery
When it comes to longer battery life, there’s no comparison between lithium and lead acid batteries. Our 12V 9Ah battery is rated to last 3,000 cycles at 80% DOD. Depending upon how often you mow your property or take your Side-by-Side out, this could easily translate to 10+ years of use. Imagine all the hunting, zipping around, and yard work you can smash out!

With zero maintenance, there’s no reason your 12V 9Ah lithium battery shouldn’t be functioning to the max. No worries with checking water levels or running to the store for distilled water. Again, lithium LiFePO4 batteries require no maintenance whatsoever.

And coming in at an impressively light 4.4 pounds, your back may last longer too. So drop your new 12V 9Ah battery in as soon as it arrives and enjoy a smoother, easier experience.

I bought my last mower battery!

I previously bought a 12v 4ah Red a few months ago for our JD X320. With leaf sweeping season upon us the 20 year old JD G100 was getting really sluggish in the starting department so I sprung for the 12v 9ah for that mower. Ive had it in a week now and I am very satisfied with the battery. After the holidays I have the RV upgrade on the drawing board, I plan on installing (3) of the Blue 125ah heated batteries.
