FAQ
What ASUS notebook models is the BTI AS-UL80 battery compatible with?
The BTI AS-UL80 is compatible with numerous ASUS ultraportable and mainstream notebook series, including UL30, UL50, UL80, PL30, PL80, U30, U33, U35, U45, and U53 models. Specific variants within these series are listed in the product documentation. This battery is engineered as a direct replacement for the original battery in these models, matching both physical dimensions and electrical specifications.
What is the capacity of this notebook battery?
This battery has a capacity of 5600 milliampere-hours (mAh). This measurement indicates the amount of electrical charge the battery can store, which directly influences how long your notebook can operate on battery power before requiring a recharge. Higher mAh values generally translate to longer runtime, though actual usage time depends on your notebook's power consumption during specific tasks.
What voltage does the BTI AS-UL80 battery output?
The battery outputs 14.4 volts direct current (V DC). This voltage is critical because it must match the notebook's designed input voltage to ensure stable operation and prevent potential damage. Using a battery with incorrect voltage can cause system instability, component stress, or failure to power on. The 14.4V DC specification ensures compatibility with the motherboard and power regulation circuits in supported ASUS notebooks.
What type of battery chemistry does this product use?
The BTI AS-UL80 uses lithium-ion (Li-Ion) chemistry. Lithium-ion batteries offer several advantages for notebook applications, including high energy density (more capacity in a smaller size), relatively low self-discharge when not in use, and no memory effect that can reduce effective capacity over time. This chemistry supports hundreds of charge cycles while maintaining safety through built-in protection circuits.
How many cells are in this battery pack?
This battery pack contains eight individual lithium-ion cells. The cells are arranged in a series and/or parallel configuration to achieve the specified 14.4V DC output and 5600 mAh capacity. Multiple cells allow for balanced energy storage and discharge characteristics while maintaining a compact form factor that fits within the notebook's battery compartment. The cell count is a key factor in both the battery's physical dimensions and its electrical performance.
What warranty coverage does this battery include?
The BTI AS-UL80 notebook battery is backed by an 18-month limited warranty. This warranty period provides coverage against manufacturing defects and premature failure under normal use conditions. For warranty service or claims, retain your proof of purchase and contact the retailer or manufacturer according to their specified procedures. The warranty demonstrates confidence in the product's reliability and quality.
What power capacity is listed for this UPS?
Power specifications help show where the unit fits best, including the type of load level, electrical environment, and backup role it is intended to support. These are usually the most decision-critical facts in a UPS or power-protection comparison.
What voltage details are listed?
The listed power specification is 14.4 V DC, which helps position the unit for the right load level and installation role.
