Antigravity ATZ-10 Re-Start Lithium Starting Battery

Antigravity ATZ-10 Re-Start battery is an ultralight and very compact Lithium Iron Phosphate (LiFePO4) battery designed as starting battery for motorcycles, smaller boats, and various Powersport vehicles.

Antigravity ATZ-10 Re-Start battery features an intelligent Battery Management System (BMS) that protects the battery from various unwanted events, combined with so-called Re-Start technology, preventing the deep discharges from leaving the users stranded due to the deeply discharged battery.

Antigravity ATZ-10 Re-Start Lithium Battery Features and Specifications

The physical dimensions of the Antigravity ATZ-10 Re-Start battery are (L x W x H) 5.9 x 3.46 x 3.62 inches (~150 x 88 x 92 mm) and thanks to a four-terminal design, the battery can be used to replace several groups of larger batteries.

As such, the battery can be used to replace YTZ10S, YTZ12, YTZ14, YTX9, YTX9-BS, YTX7A-BS, YT12A-BS, and similar batteries.

Note: If the battery is used for motorcycles and similar applications, the motorcycle must NOT be older than 20-25 years and it must NOT have an old-style battery charger that actually uses a battery to smooth voltage spikes. If the battery is used for such a vehicle, replace the voltage charge controller with a newer one.

The battery weighs only 2.6 pounds (~1.2 kg) which is almost nothing for a battery that features 360 Cranking Amps.

The Antigravity ATZ-10 Re-Start battery features a nominal capacity of 6.1 Ah, but in terms of Cranking Amps, it is equivalent to Lead-Acid batteries in the 10-12 Ah range.

But, unlike lead-acid batteries, the Antigravity ATZ-10 Re-Start battery can be mounted in any position, supports at least twice as many cycles as a good lead-acid battery, and have a much lower self-discharge rate.

One of the very specific features of the Antigravity ATZ-10 Re-Start battery is its intelligent Battery Management System (BMS) which is used to equalize the cells but also protects the battery from unwanted events, including over-discharge protection, over-charge protection, and thermal protection.

Also, the BMS features a low-voltage cut-off combined with the Re-Start technology - if the battery s deeply discharged, the BMS disconnects the battery from the rest of the electric system, allowing the user to restart (hence the name) the battery while still holding enough charge for a successful cranking attempt.

Such a system can come in handy in many situations.

How To Charge Antigravity ATZ-10 Re-Start Lithium Battery

When the Antigravity ATZ-10 Re-Start battery is placed in the motorcycle or similar vehicle with a modern charge controller (less than 20 years old), let the vehicle keep the battery charged.

If the vehicle is going to be stored for a longer period of time, especially during winter cold or summer heat, take the battery out, recharge it every 3-4 months using a dedicated lithium battery charger and keep it in the area at room temperature or a little bit lower.

Considering the battery's capacity, suitable lithium battery chargers are ones with a charging current in the 1-3 Amps range.

For example, if the battery is discharged down to 50% DoD, a 2 Amps battery charger will recharge it completely in less than two hours.

Antigravity ATZ-10 Re-Start Battery As Deep Cycle Battery

Antigravity ATZ-10 Re-Start battery tolerates deep discharges relatively well, much better than the equivalent AGM or other lead-acid battery.

However, the battery is not intended for deep-cycle applications, and it should not be used as such.

Just be sure to find the battery that fits your size, capacity, battery terminal type, and discharge requirements.

Long Story Short: If You are looking for a compact and lightweight cranking battery for your motorcycle, ATV, or similar vehicle, consider Antigravity ATZ-10 Re-Start battery.

Despite its ultralight design and compact design, it is able to provide 360 Cranking Amps, it features intelligent BMS combined with Re-Start Technology, and thanks to the four-terminal design, it can be easily fitted in many battery compartments.
