Battery & Charger Maintenance

Lithium-ion batteries, like the pack used in your STACYC, naturally self-discharge at a rate of approximately 1% of their capacity per day when not in use. This self-discharge occurs due to internal chemical reactions within the battery, even when it’s disconnected from a device. Over time, such as during extended storage, this can lead to a significant reduction in charge. For example, after a month of inactivity, the battery could lose around 30% of its capacity. To minimize this effect, it’s recommended to cycle the batteries on the charger every couple of weeks when they're not in regular use.

Since STACYC lithium-ion battery pack undergoes heavy load cycles, its life expectancy and care are influenced by the demands placed on it. With gear reduction, the motor draws significant power under load (e.g., climbing hills or carrying close to the max weight), which can stress the battery. Typically, a lithium-ion battery like this lasts 1-2 years of regular use depending on how often it’s cycled and how it’s maintained.

STORAGE AND CARE TIPS

• Charge Smartly: Avoid letting it fully drain during rides, as deep discharges under heavy loads can wear it out faster.
• Watch the Heat: Heavy loads (like maxing out the 75-115lb. limit or tough terrain) can heat up the battery, especially with gear reduction pulling more current. Try to avoid prolonged high-load use without breaks.
• Short Breaks: If the STACYC is being used intensely (e.g., long rides or frequent starts/stops), give the battery occasional rest periods to cool down.
• Storage: For off-season or long breaks, store the battery in a climate-controlled environment and cycle on the charger every couple of weeks.  

Given the heavy load cycles, you might notice reduced runtime after a year or so of frequent use, but proper care can stretch its lifespan.
