🔋 90-day warranty is the industry standard for replacement batteries. Batteries naturally lose capacity over time — this normal wear is not covered. Warranty applies to manufacturing defects only.

Compatible battery models (interchangeable): BL-A7CT / BL-A1CT
Capacity: 4020mAh / 15.28Wh
Rated voltage: 3.8V
Charge limit voltage: 4.4V
Battery type: Li-ion Polymer (Grade A cells)
Compatible with: Global3 b01, global3 bo1
Package include: 1 x battery
This BL-A7CT / BL-A1CT 4020mAh Li-ion Polymer replacement battery restores full power to your Global3 b01 or global3 bo1 device. Both battery models are fully interchangeable — meaning BL-A7CT can replace BL-A1CT, and BL-A1CT can replace BL-A7CT without any modification or compatibility issues. This flexibility makes finding the correct replacement easier since either model will work identically. Built with grade A cells and multi-layer safety protection against overcharge, over-discharge, and short circuits. CE, RoHS, and UN38.3 certified.
Key Feature — Interchangeable Battery Models: The Global3 b01 and global3 bo1 devices were designed to accept either BL-A7CT or BL-A1CT battery models. Both batteries share identical physical dimensions (length, width, thickness), the same 4020mAh capacity, the same 3.8V nominal voltage with 4.4V charge limit, and the same small 2-pin connector orientation. Whether your original battery is labeled BL-A7CT or BL-A1CT, this replacement battery will work perfectly. This interchangeability is uncommon in portable electronics — most devices require exact model matching. For users who cannot find their specific model in stock, the alternative model provides a direct solution. If your device now requires frequent charging, powers off before reaching zero percent, or runs significantly shorter than when new, this replacement battery restores the original 4020mAh capacity. The 4020mAh rating provides sufficient runtime for extended use between charges.
Compatibility Note: Fits Global3 b01 and global3 bo1 devices only. Please check your original battery label — if it shows BL-A7CT or BL-A1CT, this replacement battery is compatible. Both models work identically, so there is no need to match the exact number. This battery is NOT compatible with Global3 other variants or different Global device models. The small 2-pin connector is keyed and only fits one way — do not force connection. Professional installation is recommended for devices with sealed casings requiring adhesive softening and careful prying to access the battery compartment.

Frequently Asked Questions

Yes, BL-A7CT and BL-A1CT batteries are fully interchangeable for Global3 b01 and global3 bo1 devices. If you need a Global3 b01 battery replacement or a global3 bo1 battery replacement, either BL-A7CT or BL-A1CT will work identically. Both battery models share the same physical dimensions, same 4020mAh capacity (15.28Wh), same 3.8V rated voltage with 4.4V charge limit, and identical small 2-pin connector orientation. For BL-A7CT BL-A1CT interchangeable battery compatibility, there is no performance difference between the two models — they were manufactured as alternative part numbers for the same device family. If your original battery is BL-A7CT, BL-A1CT works perfectly. If your original is BL-A1CT, BL-A7CT works perfectly. This replacement battery covers both scenarios, eliminating the confusion of finding the exact model number. Please verify that your device is Global3 b01 or global3 bo1 before ordering.

This BL-A7CT / BL-A1CT 4020mAh replacement battery has a typical capacity of 4020mAh (15.28Wh) and a rated voltage of 3.8V, with a charge limit voltage of 4.4V. The battery supports standard 5V/2A charging (10W) — for Global3 b01 battery specifications and global3 bo1 battery charging, the device does not support fast charging protocols like QC or PD. Using a standard charger is recommended for optimal battery longevity. This 3.8V 4020mAh Li-ion Polymer battery is built with grade A cells and is CE, RoHS, and UN38.3 certified. For Global3 b01 battery life expectations, a fresh 4020mAh battery typically provides extended runtime suitable for daily use. Standby time with the device idle is substantial. When replacing an aging battery that no longer holds charge, users typically notice significant improvement in both runtime and device stability — old batteries often cause unexpected shutdowns that a fresh battery eliminates.

Professional installation is recommended for Global3 b01 battery replacement and global3 bo1 battery replacement. Both devices have sealed casings that require heating to soften adhesive before opening. To replace battery in Global3 b01, carefully pry the casing open with a plastic spudger to avoid damaging internal components. The battery sits connected to the mainboard via a small 2-pin connector — disconnect by pulling the plug (not the wires). For BL-A7CT BL-A1CT battery installation, connect the new battery (connector is keyed, only fits one way), place it in the compartment, then reseal the casing. Third-party repair shops typically charge $15-30 for labor. For battery health maintenance: 1) Use only a standard 5V/2A charger — avoid fast chargers. 2) Keep charge level between 20% and 80% for daily use to maximize lifespan. 3) Avoid exposing the device to high temperatures (above 40°C / 104°F). 4) For long-term storage (over 2 months), keep the battery at approximately 60% charge. 5) Perform a full calibration cycle after installation: drain until auto-shutoff, then charge uninterrupted to 100%. For Global3 b01 battery care, stop using immediately if the battery shows any swelling.
