Dongjin UPS Battery refers to UPS (Uninterruptible Power Supply) batteries manufactured by Dongjin Group, a company known for producing lead-acid and lithium batteries used in UPS systems, solar energy storage, telecom, and backup power applications. Dongjin has global operations including a presence in Pakistan, and its batteries are commonly used as both original and replacement UPS batteries.
🔋 What Dongjin UPS Batteries Are
-
Battery Type: Mostly Valve Regulated Lead Acid (VRLA) sealed maintenance-free batteries (SMF), and also LiFePO₄ lithium batteries in some product lines.
-
Use Cases: Designed for UPS systems, emergency lights, IPS, fire alarm systems, solar energy storage and other backup power applications.
-
Technology: Many lead-acid variants use AGM (Absorbent Glass Mat) technology for reliable discharge and low maintenance.
-
Maintenance: Sealed and maintenance-free, no need for topping-up fluid.
-
Lifespan: Designed for multiple years of service depending on use and environment.
🔋 Common Dongjin UPS Battery Types
Here are typical lead-acid UPS battery models you’ll find in the Dongjin lineup (mostly 12 V):
| Model | Voltage | Capacity | Notes |
|---|---|---|---|
| DJ12-9 | 12 V | ~9 Ah | Small UPS or emergency lighting |
| DJ12-26 | 12 V | ~26 Ah | Mid-small UPS and power backup |
| DJ12-70 | 12 V | ~70 Ah | UPS / IPS / telecom backup |
| DJ12-100 | 12 V | ~100 Ah | Common UPS / solar backup |
| DJ12-120 | 12 V | ~120 Ah | UPS and higher capacity setups |
| DJ12-150 | 12 V | ~150 Ah | Larger UPS / energy storage |
| DJ12-200 | 12 V | ~200 Ah | Heavy duty backup / solar systems |
⚡ These are sealed lead-acid (VRLA-AGM) maintenance-free batteries suitable for UPS or similar backup applications.
🔋 Lithium Battery Options (Advanced)
Dongjin also offers LiFePO₄ lithium batteries, often branded as DJDC series, for longer lifespan and deeper cycles:
-
DJDC 12V 100Ah LiFePO₄ – smart display, Bluetooth/BMS protection, high cycle count.
-
DJDC 24V / 48V LiFePO₄ – used for solar + UPS energy storage systems with long life and safety features.

🧠 Tips When Choosing a Dongjin UPS Battery
🔹 Match the Voltage: For most UPS systems, 12 V is standard.
🔹 Choose Ah Based on Runtime: Higher Ah means longer backup time.
🔹 Consider Lithium vs Lead-Acid: Lithium (LiFePO₄) lasts longer and supports deeper discharge, but is more expensive.
🔹 Check Terminal Type & Size: Make sure it fits your UPS battery tray.
