SUPER EMPOWER 12100-70L 12V 100Ah LiFePO4 Lithium Battery – the Ultimate Lightweight Power Upgrade
I swapped out my old heavy lead unit for this lithium option last summer, and I noticed the weight difference right away. It feels almost empty when you pick it up, but do not let that fool you. This thing packs a massive punch, and it holds a charge through cold weather like nobody’s business. You get steady power for days, which makes camping trips or tailgating so much easier.

Plus, the built-in management system keeps things safe, and you do not have to worry about acid leaks or corrosion ruining your engine bay.
Installation took about twenty minutes since the terminals lined up nicely with my factory cables. You just need to make sure you bolt it down tight because it weighs so little compared to stock parts. Honestly, once you make the switch to lithium, you will never want to go back to the heavy old style.

What to Look for Before You Buy Best Battery for Ssangyong Rexton
Group Size
You need to match the physical dimensions of your stock housing so the new unit sits securely. If you buy the wrong group size, the hold-down clamp will not fit right, and the unit could slide around. Take five minutes to measure your tray before you spend any money.
A loose power source will rattle against your engine components and crack the plastic case over time. Always double-check your owner manual or measure the old unit twice to avoid annoying returns later.
Cold Cranking Amps
Cold cranking amps tell you how much power the unit delivers when temperatures drop below freezing. If you live in a snowy climate, you need a high rating so your engine starts on bitter mornings. Weak ratings will leave you stranded when winter hits hard.
Do not skimp on this number if your local winters bring heavy frost and freezing wind chills. Pay a little extra for high cranking power, and you will thank yourself on the coldest day of the year.
Reserve Capacity
Reserve capacity measures how long your electronics run if your alternator stops working on the highway. A higher rating gives you extra time to pull over safely without losing your headlights or power steering. This metric matters a lot if you run extra gear like winches or fridges.
Think about your daily driving habits and accessories before deciding how much reserve power you actually require. More reserve time always beats running out of juice in the middle of nowhere.
Battery Chemistry
You have to choose between traditional flooded options, AGM mats, and modern lithium setups for your SUV. AGM units resist vibration and handle accessory loads much better than old flooded styles. Lithium weighs next to nothing, but your wallet will take a bigger hit upfront.
Pick the chemistry that matches your budget and how hard you plan to push your electrical system. Each type has distinct pros and cons depending on your specific driving style.
Terminal Location
Your factory cables have fixed lengths, meaning the positive and negative posts must line up perfectly. If you buy a unit with reversed terminals, your cables might not reach or could stretch dangerously. Always look at your old setup and compare the post layout before ordering.
A simple mix-up here turns a quick ten-minute swap into a frustrating afternoon of splicing wires. Save yourself the headache and verify the terminal orientation twice.
Warranty Coverage
A strong warranty tells you the manufacturer actually trusts the build quality of their power units. Look for at least a three-year replacement window so you are covered if a bad cell pops up early. Cheap units with short warranties usually fail right after the coverage expires.
Keep your receipt in the glove box so you can claim a free replacement if things go sideways. Good warranty support protects your hard-earned cash from factory defects.
- ✔︎Match the exact BCI group size to your factory tray
- ✔︎Prioritize high cold cranking amps if you live in cold regions
- ✔︎Look for high reserve capacity if you run aftermarket accessories
- ✔︎Choose AGM or lithium for better vibration resistance
- ✔︎Verify terminal post locations before buying your unit
- ✔︎Demand at least a three-year replacement warranty
Frequently Asked Questions
Is It Hard to Install a New Power Unit in My Driveway?
You can swap your power unit in about twenty minutes with basic hand tools like a ten-millimeter wrench. I changed mine right in the garage last month, and you just need to disconnect the negative terminal first. Make sure you lift the heavy box carefully so you do not hurt your back on the metal tray.
Can I Use a Marine Option for My Daily Commuter SUV?
Marine boxes work fine for daily driving as long as the physical dimensions fit inside your engine bay. I ran a marine setup in my truck for three years without any issues at all. Just verify that the cold cranking amps meet your engine requirements before dropping it in place.
Do I Need to Clean My Terminal Clamps Before Installation?
Dirty terminals cause a bad electrical connection, which stops your starter from getting the power it needs. I scrub mine with a wire brush and a bit of baking soda until the metal shines like new. That quick step prevents annoying corrosion from ruining your brand-new hardware.
How Long Does a Quality AGM Unit Usually Last?
A good AGM setup typically lasts between four and six years depending on your local climate and driving habits. My last one pushed past five years before it finally started cranking a bit slow in winter. Extreme summer heat usually kills them faster than freezing cold weather ever does.
Is It Safe to Transport a Lithium Upgrade in the Trunk?
Lithium units are very safe because they feature internal management systems that stop short circuits automatically. I tossed mine in the backseat last summer and drove down a bumpy dirt road with zero problems. You still want to strap it down securely so it does not slide around while driving.
Will a Mismatched Size Damage My Alternator Over Time?
Using an undersized unit forces your alternator to work overtime trying to keep everything charged up properly. I learned that lesson the hard way when my old alternator burned out early. Always match the factory specifications so your entire electrical system stays happy and balanced.
Do I Get Better Performance with an Upgraded Power Unit?
You will notice faster engine starts and brighter headlights immediately after dropping in a fresh, high-output unit. My dashboard lights stopped flickering at idle the second I installed my new AGM setup. It makes the whole electrical system feel crisp and responsive again.
Can I Maintain an AGM Unit with a Standard Charger?
Standard chargers work fine for AGM units as long as they feature an automatic shut-off feature to prevent overcharging. I use a smart trickle charger in my garage whenever my truck sits for more than a week. Avoid old manual chargers because they can easily boil the internal mats dry.
What Causes a Brand New Power Unit to Die Overnight?
An interior light left on or a failing alternator diode will drain a fresh unit flat by morning. I left my glove box cracked open once, and my brand new setup was completely dead at sunrise. Always check your accessory fuses if you suspect a parasitic drain is hiding somewhere.
Does the Warranty Cover Damage From Deep Winter Freezing?
Most standard manufacturer warranties cover internal factory defects, but they usually exclude damage from total neglect or freezing. I read the fine print on mine, and it protected me when a bad cell developed after six months. Keep your purchase receipt handy just in case you need to file a claim.
