I picked up the Elecstor Mercury Edition 100W 75WH LiFePO4 Mini UPS today.

It's on sale for R429 @ Takealot.

This should be below cost, surely? It's a steal. The black version goes for R999 @ Takealot. The same one goes for R1 436 @ Geewiz. These were prices above R1600 in when loadshedding was still a daily occurrence.

This is still on sale at the same discounted price. The seller is clearly trying to offload stock. I suspect simply because batteries can't be sitting idle till the end of time. I'm happy I got one unit at this price, and only wish I didn't have to spend R1.6k for a similar unit at the height of loadshedding a couple of years ago.

Price is back up to R1789. That was a bargain!

Same paid a grand cost for mine now they selling for like R380 or something.

prob written off stock like the others.

Many options though which is great.

How is yours holding up since that long ago assuming you talking about 2023.
 
For those who want a refresher on volts, amps and ohms:

That said anyone know where you can buy the replacement battery packs for these things? They all use the same battery pack.

Try them they have a lot of different battery packs available.

Considering how heavily marked down they are new isn't cheaper to replace it outright?

Just replace the cells with LG HG2 3000mah/Samsumg 30Q 3000mah @ R89 each. I would not buy no name/Andowl/ZYF from electroman or like @airborne has stated replace unit.

Well I guess you can just buy new units each time but the battery packs in them are still pretty bad. Buying these replacement LG or Samsung might be worth it.

Cell's from "dead" laptop battery packs are always high quality, before opening them just make sure they use 18650 cells and not lipo pouches.

Yeah all these units have the cheapie cells in it. I buy from Potensa if I need lots of batteries but for the odd ones I just buy from Bossvape.

I just did that and they measured about 250-300 mA each (from 1800-2000 new). Even with 6 of them I can't think of a use for 6 Wh of capacity in 18650 form...

Wow, they must have been cycled a hell of a lot

They were junk no-name cells and degraded super fast early on, maybe down to 80% over the first 20 cycles. Then they were held at 100% for a couple of years. This was a replacement for the original battery.

The original didn't do much better and allegedly its cells are Panasonic. But, it's been a more graceful decline, so still usable after 10 years.
 
Coming back to this thread, I got a Elecstor 24000mAh DC-DC UPS earlier this year and decided to do a benchmark on it yesterday.

I unplugged it at ~10:15 and it died at 15:30.

The output watts was 20W non continuous, 11W only for the router and ONT and peaked at 20W while charging a phone as well.

Battery life calculator suggests that the runtime for 20W is ~14 hours.

Which one is more likely, 5.5 hours or 14? 5.5 seems too short and 14 seems to long.

It's rated 75 Wh isn't it?

75/20 = 3.75 hours

So it sounds about right. Your average load was probably more like (75/5.5 = ) 13 W.

(The mAh rating of these things is worse than useless. Capacity depends on a second factor, namely cell voltage, which in this case is apparently 3.125 V. Only use Wh when comparing UPSes.)
