Industrial Battery Charger Repair Services
Component-level repair for forklift chargers, float cum boost chargers (FCBC), SMPS and thyristor battery chargers. Load-tested before dispatch, with warranty on every repair.
When a battery charger fails, your forklifts stop moving and your backup batteries stop charging. GRD Solutions repairs industrial battery chargers for warehouses, factories, power plants and utilities across India, and gets them back in service fast.
Our engineers repair chargers down to component level. We fix control cards and PCBs, rectifiers, thyristors and transformers, and recalibrate float and boost settings so your batteries charge correctly. Battery charger repair usually costs far less than a new charger, and it is often the only option for older or discontinued models.
We repair DC battery chargers from 24V to 72V, including traction chargers for forklifts and stackers, FCBCs for substations and UPS systems, and DG set battery chargers.
Battery Chargers We Repair
We handle output voltages from 12V and 24V up to 48V, 72V DC.

Common Battery Charger Problems We Fix
Call us if your charger shows any of these faults:
Battery charger not charging, or the forklift charger not charging the battery fully
Battery charger not working at all, or no output voltage
Charger stuck in boost mode, or not switching to float
Low output voltage or unstable charging current
Overcharging, which shortens battery life and causes gassing
Overheating, tripping or the input fuse blowing repeatedly
Error codes or a display that is not working
Most of these faults can be repaired without replacing the charger.

Battery Charger Repair — Frequently Asked Questions
How much does battery charger repair cost?+
It depends on the charger type, its rating and the fault. We evaluate your charger free of charge and send a written quote within 24 hours. Repair usually costs a fraction of a new industrial charger.
Should I repair or replace my industrial battery charger?+
Repair is usually faster and cheaper, especially for high-rated FCBC and thyristor chargers. It is often the only option for discontinued models. If a unit is not worth repairing, our fault report will say so.
What is a float cum boost charger?+
A float cum boost charger (FCBC) keeps a battery bank fully charged on a low “float” voltage and switches to a higher “boost” voltage to recharge it quickly after a discharge. FCBCs are common in substations, control rooms and UPS systems.
Why is my battery charger not charging?+
Common causes are a failed rectifier or thyristor, a faulty control card, a blown fuse or a wrong voltage setting. Our evaluation finds the exact cause.
My charger is stuck in boost mode. Can it be fixed?+
Yes. This is usually a control card or sensing fault. We repair the board and recalibrate the float and boost voltages.
Do you repair forklift battery chargers?+
Yes. We repair forklift, stacker and reach truck chargers, including Toyota 48V charger boards, and chargers for JLG and Dingli aerial work platforms.
How long does an industrial battery charger last?+
A well-maintained industrial charger often runs for many years. Regular servicing and timely component repair extend its life and protect your batteries.
Do you offer an AMC for battery chargers?+
We can maintain your charger fleet under an annual maintenance contract, with scheduled checks and priority repair.
Do you repair chargers from other states?+
Yes. We serve customers across India. Courier the charger to our workshop and we ship it back after repair and load testing.
