Acid Accumulator Manufacturer,Supplier and Exporter in India
Product Code : EL-SLE-4822
Jlab Export is a leading Acid Accumulator Manufacturer,and suppliers in India
Acid Accumulator (code EL-SLE-4822) is a lead-acid storage cell used for demonstrations in physics laboratories, showing how electrical energy is stored as chemical energy and given back on discharge. It is built from lead with dilute sulphuric acid as the electrolyte, housed in a plastic container, and listed in a 2 V, 20 Ah version. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

How Does It Compare with Other JLab Accumulators?
| Model | Voltage and capacity (as listed) | Container | Other listed details |
|---|---|---|---|
| This accumulator (EL-SLE-4822) | 2 V, 20 Ah; also a “6C 15AH” version | Plastic | Lead with dilute sulphuric acid; for physics lab demonstrations |
| Accumulators | 2 V in 45, 60 and 75 Ah | Plastic | Multi-plate type with positive and negative plates, for heavy current loads |
| Lead Accumulator | 2 volts, 120 amps | Hard rubber with plastic lid | Multiple type, screw terminals, supplied with charging instructions |
This accumulator is the smaller-capacity choice for bench demonstrations and routine circuit work. The multi-plate accumulators suit buyers who need more ampere-hours for heavy current loads, and the hard-rubber lead accumulator is listed with screw terminals and charging instructions.
What Is the Acid Accumulator Used For?
A lead-acid accumulator is a secondary cell: it can be charged from a DC supply, store the energy chemically, and then be discharged through a circuit many times over. On discharge both sets of plates change towards lead sulphate and the acid becomes weaker, so its specific gravity falls; charging reverses the reaction. Teachers use it to contrast rechargeable cells with primary cells such as the Daniell and Leclanché cells, and the lead storage battery is part of electrochemistry in class 12 chemistry. Because it holds a steady voltage, a lead-acid cell is also a common driver cell for potentiometer experiments on emf and internal resistance in class 12 physics.
Handle the electrolyte with care: dilute sulphuric acid is corrosive, so wear goggles and gloves and keep a bench cloth and water nearby. Charge in a ventilated room away from flames or sparks, because hydrogen and oxygen are given off near the end of charging; connect positive to positive, never short-circuit the terminals, and top up with distilled water only. A battery hydrometer shows the state of charge from the acid’s specific gravity.
What to Specify When Ordering
- Version — the 2 V, 20 Ah accumulator or the version listed as “6C 15AH”; state the voltage you need so JLab can confirm.
- Electrolyte — ask how the accumulator will be supplied (with or without acid), as this affects packing and export shipping.
- Quantity — the minimum order is 10 units.
- Accessories — add a battery hydrometer or connecting leads to the same enquiry if needed.
Frequently Asked Questions
What voltage and capacity does the accumulator have?
The main version is rated 2 V and 20 Ah. A second version appears in the listing as “6C 15AH”, which gives a 15 Ah capacity; please confirm its voltage with JLab before ordering.
What does a 20 Ah rating mean?
The ampere-hour rating is the charge the cell can deliver: in principle one ampere for about 20 hours, or a larger current for a shorter time. In practice the usable capacity falls at high discharge currents.
Is the sulphuric acid supplied with the accumulator?
The listing names dilute sulphuric acid as the electrolyte but does not say whether units are shipped filled. Filled lead-acid batteries are regulated as dangerous goods in transport, so ask JLab how your order will be supplied, especially for export.
How can students check whether it is charged?
Measure the specific gravity of the electrolyte with a battery hydrometer: it is highest when the cell is fully charged and falls as the cell discharges. A voltmeter reading across the terminals gives a second check.
Is a charger included?
A charger is not part of this listing. Use a DC charger suited to lead-acid cells and follow the polarity markings.
What details does JLab need for an export quotation?
The quantity, destination country and port or city, delivery terms such as FOB or CIF, any packing or labelling requirements, and the tender reference where there is one.
Who manufactures this accumulator?
Jain Laboratory Instruments Pvt Ltd (JLab) makes it at its works in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a physics and science laboratory equipment manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. JLab makes this accumulator in its own works rather than buying it in from a trader, so schools, colleges, dealers and importers get factory-direct supply, every unit is inspected by eye before it is packed, and repeat orders are handled by the manufacturer itself. JLab exports worldwide and ships to buyers in every region, for example Samoa in Oceania, Bangladesh in South Asia, Costa Rica in Central America and the Caribbean, the USA in North America and Chile in South America. Tender buyers can refer to the JLab lab tenders page.
