Product Features

VEHICLE & STANDBY GENERATOR COMPATIBILITY: Designed for Nissan Sentra, Versa, and Juke; Mazda 2, Mazda 3, and MX-5 Miata; Honda Prelude; and Kohler or Generac home standby generators. Directly replaces Group 51, 22NF, Deka 651MF, Duralast 51-DL, and Kohler GM106374-S batteries. Not compatible with Group 51R right-positive configurations.
BLUETOOTH APP MONITORING & ONE-TAP EMERGENCY RESTART: The built-in Bluetooth 5.0 module connects to your smartphone for real-time monitoring of battery voltage, capacity percentage, and charging status through the app. During parasitic power drain or extended generator standby, the Smart BMS helps preserve a 20% energy reserve, allowing you to reactivate the battery and start the engine with a single tap without opening the hood.
ENHANCED CRANKING POWER & LIGHTWEIGHT DESIGN: Delivers up to 750 CCA of peak cranking power and 28Ah capacity, equivalent to 35Ah PbEq. It provides over 50% greater starting power than standard 425–500 CCA Group 51 lead-acid batteries. Weighing just 8.8 lbs (4 kg), it reduces weight by more than 20 lbs compared with 30 lb AGM batteries, making installation easier while helping improve vehicle handling.
GROUP 51 DIMENSIONS & LEFT-POSITIVE FITMENT: Measures 9.33 x 5.08 x 7.87 in (237 x 129 x 200 mm), with an overall height of 8.70 in (221 mm). Features top-post SAE terminals and left-positive [+ -] polarity. Designed as a direct drop-in replacement for compatible left-positive vehicle battery trays and standby generator installations without modifications. Always verify terminal orientation before purchasing.
SMART BMS & INTEGRATED LCD DISPLAY: Built with Grade-A CATL LiFePO4 cells and an intelligent Battery Management System, this battery helps protect against overcharging, over-discharging, overcurrent, thermal overload, and cell imbalance. The integrated LCD screen displays real-time voltage and capacity percentage at the press of a button, making it easier to check battery condition during everyday use and extended generator standby.
IP66 WATERPROOF PROTECTION & ACID-FREE CONSTRUCTION: The fully sealed, heavy-duty ABS housing provides IP66-rated protection against water, dust, rain, and harsh operating conditions. Its dry, acid-free design eliminates acid leaks and corrosive fumes while helping prevent terminal corrosion and protecting engine wiring harnesses and generator battery trays.
CHARGING VOLTAGE REQUIREMENTS & REGULATOR WARNING: Use only with vehicle or generator charging systems equipped with a suitable regulator that maintains a stable output below 15.0V. Unregulated systems or those exceeding 15.0V must be upgraded before use to help prevent BMS shutdown or battery damage. Verify the maximum charging voltage before installation; 14.4V ±0.2V is optimal. For standalone charging below 0°C (32°F), use a dedicated 14.6V LiFePO4 charger. Alternator charging while driving or generator charging while running in subzero temperatures is supported. With a monthly self-discharge rate below 1%, the battery helps maintain readiness during extended standby periods.

FAQS

How do I charge a lithium battery?

TYKOOL Lithium LiFePO4 batteries perform best when charged by a LiFePO4-compatible battery charger. LiFePO4 batteries require a different charging profile and voltage requirements compared to traditional battery chargers. Chargers designed for different chemistries may work, but they may not charge a TYKOOL Lithium battery to full capacity. It’s important to select a charger that has a LiFePO4-compatible constant-current constant-voltage (CC/CV) charging profile, provides the correct charging voltage for your battery, does not exceed the charge current (amp) for the battery, and has a charge indicator LED to let you know when the battery is fully charged. If you need help finding a compatible charger for your TYKOOL Lithium battery, or if you want to check your current charger compatibility, please reach out to our support team.
What vehicles/devices are these batteries compatible with?

Our 12V lithium phosphate (LiFePO4) batteries are designed to start a wide range of 12-volt systems, including:

- Motorcycles (Scooters,cruisers, sport bikes, dirt bikes)

- ATVs/UTVs (all-terrain vehicles)

- Boats/PWC (personal watercraft, jet skis)

- Snowmobiles

- Lawn mowers, tractors, and riding lawn equipment

Check your owner’s manual or contact us to confirm sizing and terminal type for your specific model.
Will this battery fit my vehicle?

We provide detailed sizing charts (length x width x height) and terminal type (top-post, side-post, etc.) in the product description. If unsure, message us with your vehicle’s make/model/year, and we’ll confirm compatibility.
Can I use my existing lead-acid battery charger?

Yes, but we recommend a LiFePO4-specific charger for optimal performance. Standard lead-acid chargers may work if they have a float mode (<14.6V). Avoid chargers with “equalization” modes, as they can damage LiFePO4 batteries.
Is Tykool battery available to use in my e-bike?

We are sorry, No. Currently we do not supply lithium type motive battery for electric vehicles like electric bikes,tricycles and cars.
Is a higher charging current safe for lithium batteries?

Yes, as long as it stays within safe limits. A charging current below 50% of the battery capacity is optimal, and any current not exceeding the battery’s rated capacity is safe. Lower current increases safety but takes longer, while higher current (within limits) reduces charging time.
What should I check before installing a lithium car battery?

Check the battery size, terminal polarity, voltage, capacity, and compatibility with your vehicle. Most importantly, verify that your vehicle’s charging system is suitable for lithium batteries and stays within the manufacturer’s recommended voltage range.

Are Lithium Batteries Safe?

TYKOOL Lithium batteries are 100% safe & reliable. Our signature chemistry, Lithium Iron Phosphate (LiFePO4), does not contain rare earth elements (like Cobalt) or heavy metals, is non-toxic, including no lead or acid, is non-corrosive, does not off gas, requires no watering or maintenance, can be placed in any orientation, and unlike other lithium batteries will not explode or catch fire. In addition, each TYKOOL Lithium battery is protected from over heating, over charging, and short circuiting, by a battery management system (BMS) microchip that also extends the lifespan and is contained in a rugged, waterproof case (although enough water can conduct electricity between the terminals, so don’t submerse the battery). For best performance & reliability we recommend using a LiFePO4 charger.
Why choose LiFePO4 over traditional lead-acid batteries?

- Lightweight: Up to 70% lighter than lead-acid batteries, reducing vehicle weight.

- Longer lifespan: 5-10x more cycles (2,000+ cycles at 80% depth of discharge).

- Faster charging: Charges 3x faster than lead-acid.

- Zero maintenance: No water refilling or acid leaks.

- Reliable starts: Stable power output even in low temperatures.
Does this battery include a built-in BMS (Battery Management System)?

Yes! All our batteries feature an advanced BMS for:

- Overcharge/discharge protection

- Short-circuit prevention

- Over current protection

- Cell balancing for maximum safety and longevity.
Can this battery handle cold weather?

Yes! Our batteries operate in temperatures from -4°F to 140°F (-20°C to 60°C). Unlike lead-acid, LiFePO4 delivers consistent cranking power in freezing conditions (ideal for snowmobiles).
How do I choose the right charger current for my 12V lithium battery?

Charger selection depends on battery capacity. A 12V 1A charger works with all capacities and offers the highest safety. A 12V 2A charger is suitable for batteries up to 4Ah, while a 12V 3A charger is recommended for batteries 5Ah and above for faster charging within a safe range.
What are the advantages of lithium car batteries over traditional lead-acid batteries?

Lithium car batteries are typically lighter, offer strong cranking power, and provide a longer cycle life than conventional lead-acid batteries. They also require less maintenance and have a lower self-discharge rate, making them a practical choice for reliable vehicle starting.
