Mercer ME 2000 WTU - Batteries

[elf_lord_ZC5]

Hi, what batteries does this unit Mercer ME 2000 WTU use.

Are they worth replacing, or should we just buy a new unit.

Thanks

That looks like it's a standard 12v 8 or 9ah battery? Okay clicked the link that is frak expensive for that.

You know if these are spill proof, as they stand on edge in the UPS box?

Was gonna post your links then I saw original = AGM

So probably has a higher cycle count than normal LA's hence the price.

LA's = Sealed

I cant find original's cycle count cause normally LA = 200-300 and AGM = 600-1200 based on DoD

What does ATM branded mean - if anything?

Noo Idea?
Could be anything including a company name.

If I had that Unit, I would rather see if I can DIY a (R5000) Hubble S-120 instead of (R7000) 6 x Yuasa's
That way I would not have to worry about Depth of discharge and also score an extra 50AH on top of it.

But then again I am a DIY type of person

Would these be a worthwhile replacement

Lithium Iron - Drop In Replacement

My thoughts as well - thanks

BIG TIME

Instead of your 50% cut off you can go down to 10% without worry about losing cycle's.

Must have 72 volts ...

Must have 72 volts ...

Oh it's in series not in parallel. Which means this is in general just a standard UPS and shouldn't be used for anything past allowing you to safely shutdown or start a bigger power source.

That sucks

 

[elf_lord_ZC5]

Unfortunately

Unfortunately

This is a UPS not an inverter then? I'd suggest getting an inverter with a hubble battery if you could get one.

 

[elf_lord_ZC5]

That sucks

The Sticker inside says 72 volts AGM
