When the power cuts, communication can't. Leolus Energy is an Indian telecom battery supplier and manufacturer building custom lithium batteries and backup packs for telecom and networking equipment — keeping routers, access points and communication devices online through outages, a growing need as homes and businesses depend on always-on connectivity.

From router UPS to wireless access points and telecom backup power, we build packs for long backup runtime, clean cut-over and the long cycle life that always-on infrastructure needs. As a factory-direct telecom battery supplier, we serve operators, ISPs and network-equipment OEMs across India without importer mark-ups or long lead times.

Telecom & Networking We Power

Router UPS

Mini-UPS lithium packs that keep Wi-Fi routers and ONTs online through power cuts.

Communication Devices

Reliable batteries for portable and fixed communication equipment.

Wireless Access Points

Backup packs for wireless access points needing uninterrupted uptime.

Network Equipment

Lithium backup for switches, gateways and edge network devices.

Fiber Communication Systems

Dependable packs for fiber and last-mile communication hardware.

Telecom Backup Power

Scalable lithium backup for telecom nodes and field equipment.

What a Telecom Backup Battery Specification Has to Pin Down

Most enquiries we receive specify capacity and voltage and stop there. For telecom & networking the parameters below decide whether the pack survives its intended service life, and they are the ones worth agreeing before a purchase order.

ParameterTypical requirementWhy it decides the outcome
Autonomy at site load Hours of backup at the site's actual measured draw Design load and measured load differ, often substantially, once every card and radio in the cabinet is counted.
Float life at cabinet temperature Calendar life quoted at real, not nominal, temperature Telecom cabinets in Indian summers run well above 40°C. Every 10°C above 25°C roughly halves calendar life; sizing at 25°C is a fiction.
Cabinet footprint and weight Fits existing rack and floor loading Lithium retrofits into cabinets built for lead-acid are usually constrained by mounting geometry, not by capacity.
Remote monitoring SNMP or protocol-level integration with the NOC A backup battery whose health is invisible to the network operations centre gets discovered at the worst possible moment.
Charge current limit Matched to the rectifier Lithium accepts charge far faster than lead-acid. A retrofit that does not limit charge current can exceed what the existing rectifier can deliver.

Three Mistakes We See Repeatedly

These come up often enough in telecom & networking projects that they are worth stating plainly. None of them are exotic; all of them are expensive to discover after tooling is committed.

1

Direct lead-acid substitution

Voltage windows, charge profiles and low-voltage disconnect points all differ. A drop-in swap without reconfiguring the rectifier and the controller shortens pack life dramatically.

2

Sizing to nameplate load

Measure the actual site draw over a week. Nameplate figures are consistently conservative in one direction and optimistic in another.

3

No thermal plan

A lithium retrofit that solves the weight problem but ignores cabinet temperature simply moves the failure from year eight to year three.

If you are working through a specification and want a second opinion before committing, send it over — we would rather flag a problem at the drawing stage than build to a spec we know will disappoint. See how our custom pack process works.

Telecom & Networking Batteries — FAQs

We build custom lithium packs and backups for router UPS, wireless access points, communication devices, network equipment, fiber communication systems and telecom backup power — designed for long backup runtime and clean cut-over.

LiFePO4 offers long cycle life and stable performance for devices that float on charge and back up frequently, which is ideal for always-on routers and network gear. We advise the right chemistry per use case.

Yes — OEM and bulk supply, factory-direct from Bangalore. Share your equipment and volume for a quote.

Yes. Most fixed telecom plant in India runs on a nominal -48V DC bus, and a LiFePO4 string for that bus is typically 15S or 16S depending on the rectifier's float and low-voltage-disconnect settings. Those two numbers matter more than capacity, because a string sized without checking them will either never reach full charge or will disconnect early. Send us the rectifier make and its configured voltage window and we will size the string against it.

Higher purchase price, lower cost per year in most Indian deployments — but the gap depends almost entirely on cabinet temperature. VRLA loses roughly half its calendar life for every 10°C above 25°C, and a great many Indian cabinets sit well above that for months. Where a site is air-conditioned and cycles rarely, VRLA can still be the rational choice. We would rather tell you that than sell you a pack you do not need.

Scale and duty cycle, and they are not interchangeable. A router UPS is a small pack keeping a single ONT or access point alive through a household outage — usually a few hours at a few watts. Site backup carries an entire cabinet of radios and cards, is sized in hours at hundreds of watts, and has to integrate with the rectifier and report health to the NOC. We build both, but they are separate designs.
