Live Maintenance Without Downtime
System availability is critical, and downtime is not an option. Chhabi’s Online Cell Booster enables precision charging and live maintenance of weak cells without disconnecting or shutting down the battery bank
Online Cell Boosters are used where battery maintenance must be carried out without taking the complete DC backup system out of service, making them suitable for UPS, telecom, healthcare, manufacturing, utility, and railway applications that require continuous power availability.

Data centres cannot afford to take critical UPS battery banks offline for cell maintenance. Online Cell Booster enables weak cells to be treated while the UPS remains operational, helping maintain backup availability for critical IT infrastructure.
Telecom exchanges rely on continuous DC backup for network equipment. Online Cell Booster allows individual weak cells to be treated without taking the complete battery system offline or interrupting essential communication services.
Hospital UPS systems support critical areas where power interruptions are unacceptable. Online Cell Booster enables cell-level maintenance while backup protection remains active for essential medical and clinical infrastructure.
Continuous manufacturing operations cannot always accommodate dedicated UPS maintenance windows. Online Cell Booster allows weak cells to be treated during ongoing operations, helping maintain battery reliability without disrupting production schedules.
Substation protection and control systems depend on continuously available DC backup. Online Cell Booster allows weak cells to be treated while the DC system remains energised, keeping critical protection and control functions available.
Railway signalling systems depend on reliable battery backup for continuous operation. Online Cell Booster supports individual cell maintenance without taking the complete backup system out of service, reducing maintenance-related interruptions.
Corrects weak cells without load disruption or system shutdown.
Sophisticated IU/IUIU and CC/CV algorithms tailored for Lead-Acid, VRLA, and Ni-Cd.
Withstands harsh plant and utility environments.
Achieves >80% efficiency, reducing energy costs and thermal stress
It's a system that charges and recovers weak battery cells while the entire battery bank stays live and connected to the load. No shutdown, no downtime — maintenance happens in the background without anyone even noticing.
A regular cell booster works offline — you disconnect the battery bank, service it, then reconnect. The online version does the same job while the system stays live. Both are effective; the choice simply depends on whether your application can afford a brief shutdown or not.
It supports Lead-Acid, VRLA, and Ni-Cd batteries — the most common types in industrial and utility setups. The charging algorithm (IU/IUIU or CC/CV) adjusts automatically based on the battery chemistry, so there's no manual tuning needed.
One session typically handles 1 to 6 cells, with output voltage adjustable from 0–12V DC and current up to 400A. For sites with larger requirements, Chhabi Electricals offers customized configurations based on your exact voltage, current, and environment specs.
Yes, that's the core engineering behind it. The weak cell is isolated electrically while the rest of the bank keeps supporting the load normally. Built-in AC input and DC output protections keep both the equipment and the operator safe throughout the process.
Power plants, oil & gas facilities, data centers, railways, substations, cement and steel plants, essentially any sector running on a critical DC backbone where an unplanned shutdown would cause serious operational or financial damage.
Chhabi Electricals is a trusted manufacturer of online cell boosters for power and industrial applications worldwide, with 60+ years of experience behind every build. Standard IP20 enclosures available, with full customization on ratings and configurations.
It depends on battery age, load cycles, and ambient temperature. Most facilities pair their battery maintenance system with a monitoring solution like Chhabi Electricals' BHMS to get data-driven alerts instead of guessing intervals.
Yes, with current ratings going up to 400A, it's built for heavy-duty industrial environments. For sites with even higher demands, Chhabi Electricals can configure the system based on specific load and battery bank requirements.
In a large battery bank, cells age at slightly different rates. A battery maintenance system and booster keeps all cells performing at a similar level by correcting voltage dips as they appear, so the bank delivers reliable, uniform output for much longer.
