[SOLVED] I need replacement batteries for my CP1300EPFCLCD-UK UPS.

[captaincandellight]

I need to know exactly what type of replacement batteries to buy for my CP1300EPFCLCD-UK UPS. I live in India. So I imported this UPS from the UK. The original batteries are two small ones connected with a jumper and one red wire from the UPS connects to one battery with a red sticker while the second black wire from the UPS connects the second battery with the black sticker. Both the batteries have something writen on the top right end that says ( CPS7-12 ) and (12V,27WPC/15min./1.30VPC/25C).

Can you please make me understand what this means. My batteries have almoust run out of power and are getting very hot very quickly every time I use them. I have also uploaded images of the batteries below please click the links and have a look. Waiting for a responce soon.

Try and find batteries similar to these;

The wires are used to have the batteries in series. You might want to avoid tinkering with the battery, since tampering with them can and will cause you physical harm.

What is the UPS powering up?

 

[captaincandellight]

I just want to know the exact battery specifications like Voltage and AH so that I can buy them in India. The UPS is powering up a low end notebook PC and a router.

From Cyber Power Systems' website:

BATTERY

Runtime at Half Load ( min ) 9
Runtime at Full Load ( min ) 2.5
Typical Recharge Time ( Hours ) 8
Start On Battery Yes
User-replaceable Yes
Battery Type Sealed Lead-acid
Replacement Battery Pack RBP0124
RBP Quantity ( pcs ) 1

The RBP0124 is made up of two 12 Volt, 7Ah SLA (Sealed Lead Acid) batteries. Make sure to get the batteries that have the F2 size terminals on them. Reuse the connector cable that is currently connecting together the two batteries.

 

[captaincandellight]

The RBP0124 is made up of two 12V, 7Ah sealed lead acid batteries

Can you please tell me how do you know it is a 12V,7Ah battery as I checked this RBP0124 replacement battery specifications at CyberPower website and I could not find it mentned any where.

 

[ko888]

My buddy owns that model of UPS and I replaced the batteries for him.

Can you please tell me how do you know it is a 12V,7Ah

It is written on the battery itseld - "7-12". And even if you get battery with different (larger) capacity, but same physical size, it will work.

 

[captaincandellight]

There are 2 12V, 7Ah batteries so is the UPS using 24V and 17AH altogether ?

How did you arrive at 17Ah?

The two batteries are wired in series so it's 24V @ 7Ah.

 

[captaincandellight]

Can I use a single brick battery of 24V and 7Ah having the same dimensiones ?

 

[ko888]

If you can get one with F2 terminals it should work.

 

[captaincandellight]

Can I use a single brick battery with a higher capacity like 40V and 17Ah having the same dimensiones ?

 

[ko888]

Can I use a single brick battery with a higher capacity like 40V and 17Ah having the same dimensiones ?

No. The 40V battery won't charge because the UPS' charging circuit isn't designed for 40V batteries.

 

[captaincandellight]

Will a instalation of two batteries consisting of 12V, 4.5Ah/20HR also work ?

You'll probably blow up your batteries/ups electronics (may be also your laptop and router).
You seem to be utterly clueless.

 

[ko888]

Will a instalation of two batteries consisting of 12V, 4.5Ah/20HR also work ?

4.5Ah batteries will result in a much shorter runtime when the UPS switches to battery backup mode. The UPS also won't meet its 1350VA load capacity.

 

[BFG-9000]

It only runs 2-1/2 minutes on the stock battery and now you want to reduce the capacity by 1/3?

Handy tip: used automobile batteries that will no longer reliably start a car are perfect for repurposing into UPS duty. At some ~100Ah they will also drop much less voltage while running such a light load so runtime can extend into hours even with not-very-healthy batteries, much longer than the stated capacity would suggest. You just have to monitor that the UPS does not overheat during prolonged operation--after all it was only designed to run for 2-1/2 minutes.

You don't want automobiile lead-acid batteries charged in closed (office) environment.

 

[BFG-9000]

A VRLA battery is essentially the same as a maintenance-free AGM car battery, only smaller. Both are unspillable so can be shipped from Amazon.

I do prefer a regular flooded cell for this application though because the high float charge of a UPS cannot help but make regular addition of water necessary for longest life, so the more sealed types simply don't last as long.

While Dan says

Charging a lead acid battery also produces hydrogen, which can be an explosion hazard in some situations but is exceedingly unlikely to be one in a home or office, because it'll just rise to the ceiling and find its way out of the building via whatever tiny cracks exist. UPS chargers shouldn't ever push car batteries hard enough that they bubble much, anyway.

, I do prefer to install car batteries remotely outdoors, especially as I am running way more than 1300VA so there are a lot of them.

 

[captaincandellight]

Can any one please tell me what is the maximum battery Ah capacity I can install with my UPS ?

 

[captaincandellight]

No. The 40V battery won't charge because the UPS' charging circuit isn't designed for 40V batteries.

So what is the maximum voltage my UPS charging circuit can handel ?

 

[Alabalcho]

Your UPS is designed to charge 2x12V batteries. That's it, nothing more, nothing less. If you want longer runtime (as it seems), you need another solution.

Thank You fot the reply.

 

[captaincandellight]

Can you please conform if the battery described in the link shall work as it says it is a VRLA batery, has AGM separator and uses absorbent glass matt technology. Link below please have a look and conform.

What do you mean by "even if you get battery with different larger capacity but same physical size it will work". Please explain in detail.
