If you are riding a ULife e-bike and the range has started to feel shorter than the day you unboxed it, you are not imagining it. Batteries are the single biggest factor in how far and how fast your bike can go, and when the original cell starts to sag, the whole ride changes. The Battery - T5 is the replacement power source designed to slot back into your specific ULife frame, restoring the voltage and capacity your controller expects.
You do not need to guess if this is the right fit. The model designation "T5" is specific to the ULife ecosystem, meaning it is built to match the physical dimensions and electrical requirements of the bikes that shipped with that battery type. If your bike came with a T5 cell, this is the direct upgrade path to get your daily commute back to full power.

What the official page actually lists
The official ULife product page for the Battery - T5 confirms that this is a dedicated replacement unit for their e-bike lineup. While the specific amp-hour (Ah) and voltage (V) figures for the T5 variant are not explicitly detailed in the public product description text provided, the page confirms the following key service details:
- Warranty: A 1-year warranty/guarantee is included with the purchase.
- Shipping: Free shipping is applied to all orders, though specific regional restrictions should be confirmed at checkout.
- Returns: Free returns and exchanges are offered, giving you a safety net if the fit is incorrect.
- Price: The catalog price is listed at $359.00 USD. It is always wise to verify the current price on the merchant page, as e-bike component pricing can fluctuate based on lithium market rates. See options
To ensure this is the correct cell for your specific bike frame, you should verify the battery label on your current unit. If your existing battery is marked as a "T5" model, this is the correct replacement. If your bike uses a different battery shape or connector, you will need to look at other ULife battery options like the E20 Pro compatible cells, though the T5 is strictly for T5-compatible frames.
Who it's for
This battery is for the practical commuter who has been riding the same ULife bike for a year or more and has noticed the "full charge" no longer lasts as long as it did. It is also for the rider who wants to keep their current bike rather than buying a new one, as swapping the battery is often the most cost-effective way to extend the life of an e-bike. If you are looking for a straightforward way to restore your ride's reliability without the complexity of a full bike overhaul, the Battery - T5 is the component that makes that possible.
Who should skip
You should skip this specific SKU if you own a different brand of e-bike, as the physical form factor and connector are proprietary to ULife. It is also not the right choice if your bike originally shipped with a different battery model, such as the E20 series, because the T5 will not physically fit or connect to those frames. If you are unsure which battery your bike uses, check the model number on the frame or the original battery label before purchasing. You can find more details on identifying your specific e-bike components in our guide to e-bike battery maintenance.

- Check your current battery label: Look for the model number "T5" on the side or bottom of your existing battery.
- Verify the voltage: Ensure the voltage matches your bike's controller requirements (typically 36V or 48V for ULife models, though you should confirm this on your specific bike's manual). See options

- Check the warranty: Note that the Battery - T5 comes with a 1-year warranty, which covers manufacturing defects.

FAQ
Is the Battery - T5 compatible with all ULife e-bikes? No, it is only compatible with ULife models that were originally designed with the T5 battery form factor. Other models, such as those using the E20 Pro battery, require different replacement units. Always check your bike's manual or the label on your current battery to confirm the model designation.
What is the warranty coverage for this battery? The Battery - T5 includes a 1-year warranty from the date of purchase. This covers defects in materials and workmanship. For specific terms and conditions, you should review the warranty policy on the ULife website, as coverage can vary by region.
How long does it take to charge a new T5 battery? Charging times can vary depending on the charger used and the state of charge. Typically, e-bike batteries of this class take 4–6 hours for a full charge from empty. It is recommended to use the original charger or a compatible one specified by ULife to ensure safe and efficient charging.
Can I install the Battery - T5 myself? Yes, if you are comfortable with basic e-bike maintenance. The installation usually involves removing the old battery from the frame, disconnecting the plug, and inserting the new T5 battery. However, if you are not confident in handling high-voltage components, it is best to have a professional e-bike technician perform the swap.
If the FAQ answered your main objections and you want current models or trial terms, see brand options.
Bottom line
The Battery - T5 is a no-nonsense replacement part for ULife e-bike owners who need to restore their bike's range and performance. At $359.00, it is a significant investment, but it is often cheaper than buying a new bike and comes with the peace of mind of a 1-year warranty and free shipping. If your current battery is failing and your bike is T5-compatible, this is the logical next step to keep your daily commute running smoothly.
