Overview
Product Overview
TM12-RT040 is the current priority model in Tuomo Tech's RT Series 12.8V LiFePO4 motorcycle starting battery range.
It provides 4Ah capacity, 320A CA, 120A CCA, and a 150 × 87 × 93mm case for applications whose capacity and installation space match this specification.
Compared with RT060, RT040 uses the same basic case dimensions while offering lower capacity and CCA. RT080 offers higher capacity and CCA but requires a taller case. Confirm terminal layout, polarity, charging-system compatibility, and fitment for each target application.

Why Choose This Model
LiFePO4 Starting Battery Platform
Built for buyers evaluating a compact lithium starting-battery specification for motorcycle and powersports applications.
Smart Restart Functions
In Smart Mode, the battery can enter a low-power sleep state near the approximately 30% reserve threshold. The Restart button, a compatible charger, or a deliberate gentle shake can wake the battery; normal road vibration is not an automatic wake-up method.
OEM Program Ready
OEM/ODM discussions can cover logo, packaging, top-cover color, display panel, terminal configuration, spacers, and selected capacity options subject to validation.

What is the difference between RT040 and RT060?
RT040 provides 4Ah, 320A CA, and 120A CCA in a 150 × 87 × 93mm case. RT060 uses the same basic case dimensions but provides 6Ah, 480A CA, and 180A CCA. Confirm the required specification and fitment before selecting either model.
How should buyers validate TM12-RT040 fitment?
Confirm battery dimensions, available installation height, terminal layout, polarity, required capacity and CCA, charging-system compatibility, and the original battery specification.
How does the RT040 Restart function work?
In Smart Mode, the battery may enter a low-power sleep state near the approximately 30% reserve threshold. It can be awakened with the Restart button, a compatible charger, or a deliberate gentle shake. Normal road vibration is not an automatic wake-up method.
Can the label and packaging be customized?
Yes. Logo, packaging, top-cover color, display panel, terminal configuration, spacers, manuals, and selected capacity options can be discussed subject to model and project validation.
