The best Zero Gravity motorcycle battery depends on your bike’s required case size, terminal layout, and cranking needs. The Antigravity ATZ-7 is best for riders who want lithium power with built-in restart and app-based battery monitoring; the Antigravity ATZ5 suits compatible dirt bikes and enduro models. For riders seeking sealed AGM alternatives, the WEIZE YTZ14S and Mighty Max YTZ14S offer 230 CCA, while the Mighty Max YTX7L-BS is a smaller, lower-output option.

Antigravity ATZ-7 With RE-START
The Antigravity ATZ-7 is a lithium motorcycle battery with 150 cranking amps and 42Wh capacity. It weighs 1.32 pounds, making it a lightweight choice for riders looking to reduce battery weight. Its LiFePO4 chemistry includes protection against overcharge, over-discharge, and excessive heat.
Best for: Riders whose motorcycle calls for a compatible ATZ-7, YTZ7S, YTZ5S, or YTZ8V battery and who want added restart and monitoring features. Built-in RE-START reserves enough power for another engine start, and a button restores power. The included BTR-3 tracker connects to an app to show voltage, cranking performance, charging system, temperature, and up to 72 days of history.
Limitation: Its 150 cranking amps may not suit a motorcycle that requires a higher-rated battery. Verify the vehicle’s specifications before choosing it.
Antigravity ATZ5 For Dirt Bikes
The Antigravity ATZ5 provides 170 cranking amps and 5Ah PbEq capacity. The listing describes it as a replacement for several battery sizes, including YTZ5S, YTZ7S, YTX4L-BS, YTX5L-BS, BTZ5S, and BTX4L-BS, as well as similar case sizes. It is presented as a lightweight lithium option for 250cc and 450cc dirt bikes and enduro models.
Best for: Dirt-bike and enduro owners whose original battery matches one of the listed replacement types. Its stated 170 cranking amps make it a stronger-output choice than the ATZ-7 in this selection, while its listed chemistry is described as having more than twice the lifecycle of traditional lead-acid batteries.
Limitation: Confirm the exact case size and terminal arrangement for the motorcycle. The listed replacement sizes do not establish fitment for every bike in those engine classes.
WEIZE YTZ14S AGM Battery
The WEIZE YTZ14S is a 12V sealed AGM motorcycle battery with 11.2Ah capacity and 230 CCA. Its listed dimensions are 5.91 by 3.40 by 4.33 inches, and its positive terminal is on the left. The product listing identifies it as a replacement for YTZ14S, GTZ12S, and PTZ12S models.
Best for: Riders who need a YTZ14S-style AGM battery with 230 CCA and want a maintenance-free, sealed design. The listing describes its VRLA construction as leak-preventing and ready to use without water topping. Compare its measurements and terminal polarity with the battery being replaced before purchase.
Limitation: This is an AGM battery, not a lightweight lithium battery. Choose it for the required AGM form and specifications rather than if your priority is the lowest possible battery weight.
Mighty Max YTZ14S AGM Battery
The Mighty Max YTZ14S is a 12V, 11.2Ah sealed lead-acid AGM battery rated at 230 CCA. It measures 6.00 by 3.44 by 4.38 inches, with positive polarity on the left and negative polarity on the right. Its listed features include spill-resistant construction, a high discharge rate, and recovery from deep discharge.
Best for: Riders whose motorcycle requires a YTZ14S-size AGM battery and whose original battery has the same terminal orientation. It offers the same stated voltage, capacity, and CCA as the WEIZE YTZ14S, with slightly different listed dimensions, so measuring the battery compartment is important.
Limitation: The listing includes the battery and screws only; it does not include a wire harness or mounting accessories.
Mighty Max YTX7L-BS AGM Battery
The Mighty Max YTX7L-BS is a compact 12V AGM battery rated at 6Ah and 100 CCA. Its dimensions are 4.40 by 2.75 by 5.19 inches, and its positive terminal is on the right. The sealed lead-acid design is described as spill-proof and capable of recovering from deep discharge.
Best for: Riders whose vehicle specifies a YTX7L-BS battery and requires this case size and terminal orientation. Its lower capacity and CCA make it a distinct option from the 230-CCA YTZ14S models; match the rating to the motorcycle rather than assuming a smaller battery will work.
Limitation: The listing includes only the battery and screws, not a wire harness or mounting accessories.
Buying Guide: How To Choose A Motorcycle Battery
Should you choose lithium or AGM?
Choose lithium when low weight is a priority and the battery’s fitment and electrical requirements match your motorcycle. The two Antigravity options list weights or cranking specifications alongside lithium features. AGM batteries are sealed lead-acid alternatives with stated capacities and CCA ratings. Do not substitute one battery chemistry for another without checking the motorcycle manufacturer’s requirements and charging-system guidance.
How much cranking power do you need?
Use the original battery’s CCA rating and your motorcycle’s manual as comparison points. In this selection, the Antigravity ATZ5 lists 170 cranking amps, the ATZ-7 lists 150, the YTZ14S models list 230 CCA, and the YTX7L-BS lists 100 CCA. These figures do not establish universal compatibility; the correct rating depends on the specific motorcycle.
Why do size and terminal polarity matter?
Measure the existing battery and compare its dimensions with the replacement. Check whether the positive and negative terminals are on the correct sides, and confirm that the terminals connect as required without forcing cables. Even batteries with similar names can have different measurements or polarity.
What accessories or extra features are useful?
The ATZ-7 includes RE-START and a Bluetooth tracker for battery and charging-system information. The Mighty Max listings state that screws are included but wire harnesses and mounting accessories are not. Check what your installation requires before buying.
Frequently Asked Questions
What does RE-START do on the Antigravity ATZ-7?
It reserves enough power for one more engine start after the battery would otherwise be completely discharged. The rider presses the built-in button to restore power, according to the product listing.
Is the Antigravity ATZ5 only for dirt bikes?
The listing highlights 250cc and 450cc dirt bikes and enduro models, and names several replacement battery sizes. Confirm your vehicle’s required battery type and dimensions before selecting it.
Are the YTZ14S batteries interchangeable?
Both selected YTZ14S models list 11.2Ah and 230 CCA, but their dimensions differ slightly. Check the original battery’s measurements, terminal polarity, and vehicle requirements before choosing between them.
Do these AGM batteries require water maintenance?
The WEIZE listing describes its AGM battery as maintenance-free and requiring no water topping. Follow the product instructions and the motorcycle manufacturer’s battery-care guidance.
Can a battery with higher CCA always replace a lower-rated one?
Not necessarily. Fit, terminal orientation, voltage, battery type, and the motorcycle’s specifications also matter. Choose a replacement that meets the vehicle’s requirements rather than comparing CCA alone.
