BATTERIES FOR TELECOM
Batteries for Telecommunications towers, Telecom applications, Telecom equipment and Telecom backup systems.
Lead crystal® batteries – for hybrid applications
Many operators who have Generator Base Station sites have either considered or implemented ‘Hybris’ sites to reduce fuel consumption and increase Generator life. Giving the Generator a break is good practice and allows periods of quiet, as well as time for Generator maintenance.
Advanced operators are now looking at how much run time they can squeeze from their batteries, vs fuel consumption and battery wear/ replacement. Finding the optimal Battery/ Generator run time is different for every site and dependent on Equipment Load, Temperature, AC, Rectifiers, Cabling a lot of other factors.
Lead Crystal® batteries 12V Front Terminal and 2V Single Cell batteries have been designed to deliver the maximum power for the longest period of time, with the highest depth of discharge and greatest heat resilience, to allow Operators to concentrate on running the site. Run your batteries, don’t let your batteries run you!
- Consider multiple cycles per day
- High DOD, up to 80%
- Cycle between 10% DOD and 70% DOD
- No equalisation Cycles every 20 cycles
- No Gassing – Can be installed in existing shelter
- High performance 12V – outperforms most 2V’s
LEAD CRYSTAL® BATTERIES - For Float & Bad Grid
Most Grid connected sites will have some form of Battery Back Up to keep the Base Station running even in the event of a power cut. In some countries, the power can be a little, unstable! In other’s, it’s difficult to remember the last time the power went off!
Lead Crystal® Batteries cope well with all scenarios. With an 18yr float application design life and a high temperature resilience, Operator’s can make the decision between optimal Base Station temperature and fuel saving, without having to worry about damaging batteries.
In bad grid applications, Lead Crystal® Battery Technology will be there when you need it. In one application in Pakistan, we learned of 6-10 outages per day – something that will trouble even the best GEL battery, but with partial state of charge use, Zero volt 100% DOD protection AND high temperature resilience, there’s now a viable and OPEX reducing solution.
- Long Float Life – 18yr design
- Only 23% life reduction at 40°C
- No cooling required – AC saving
- Partial State of Charge use
- 100% DOD cycling
- Zero Volt recovery
- More Cycles
- Heat Resilience
- Fast Charge
LEAD CRYSTAL® BATTERIES - For Solar Applications
Pure Solar or ‘Offgrid’ Base Station sites are becoming more common as Operators look for ways to power sites without Grid connection or without Diesel Generators. Surprisingly, even in a region where there is an abundance of sun, Solar sites are still quite difficult to correctly size, manage and maintain. How many days autonomy? What is the optimum DOD? Should the batteries be cooled? What about the increased load of the cooling?
Lead Crystal® Batteries includes a range of Deep Cycle 2V batteries that do not require cooling and last significantly longer than the best of class OPZV/ GEL batteries we have compared against.
- True Deep Cycle – with 600+ Cycles at 100% DOD
- Deep Cycle – with 1250+ Cycles at 40°C, 80% DOD
- High Temperature Resilience
- Zero Volt recovery
- Slow start charging – in tune with solar cycle
- Fast charging – Over rate PV for faster charge. up to 0.3C for up to 90%
UNDERSTANDING REDUCED OPEX AND TCO
In our region, the heat of summer has a significant drain on traditional Pure Lead Batteries. For Lead Acid/ GEL/ AGM, heat can cause battery life loss of 50% for every 8°C above 25°C – compared to just 12.25% for Lead Crystal Batteries. When calculating the damage heat does to the batteries, you have to take into account the average temperatures for the region if you don’t have AC in your base stations, or the cost of cooling if you do. Our TCO modeller will show the effects of turning your AC down or having no AC on different types of battery.
Depth of Discharge
How many cycles will the battery deliver at what depth of discharge? When you’re comparing batteries, a good starting point is how many cycles each make of battery will do at say, 50% DOD. This number is usually stated at 20°C or 25°C. Remember, that’s OK if your Base Station is cooled, but you must reduce the number of cycles dependent on temperature – or perhaps you can calculate the effects of no A.C. and saving money?
The number of cycles supported will also allow you to decide if you want to cycle the batteries once, twice or perhaps three times a day, with smaller cycles prolonging the battery life or deeper cycles providing the optimum generator load and fuel efficiency.
Lead Crystal® batteries typically perform at about 2X the cycles of Lead Acid/ GEL/ AGM at 25°C. In fact, Lead Crystal® will usually deliver more cycles at 40°C than competitors do at 25°C – allowing you to choose between longer life between swap outs and turning off your AC – or both!
From calculations we have made while supporting Operators in the region, switching a Base Station AC to a higher setting, cycling to 60% DOD twice a day and adding the benefit of 93% charge efficiency can save a massive 30% or 16lt of generator fuel per day per site. That’s $8 per day – or $3,000 per year!
BATTERY SECURITY & THEFT PREVENTION
With Battery theft an increasing problem in the region, we have developed a range of solutions for Battery Theft prevention and Theft Management. When categorising battery theft, you must understand what is driving the theft. Is it opportunistic? Is it for personal power requirements? Perhaps it’s more to do with the value of Lead? When Battery thieves target a Base Station site, intent on getting the batteries out, the damage they can do is far in excess of the value of the batteries, often damaging shelters and equipment.
There are a number of steps that can be used to help in the fight against battery theft including:
- Utilising heavy, 2V batteries – these require lifting equipment to move and will deter almost all but organised crime.
- Installing Battery Safes / Tethering Equipment
- Branding or producing batteries with markings unique to the Operator
- Invisible markings (UV/ RFID)
Lead Crystal® Batteries has a number of theft reduction/ security options. Contact us for further details.
