Router Battery Backup

[Frequent visitor]

Has anyone actually noticed whether their fiber line stays connected during load shedding?

Mine remains unconnected as before!

Yup, most ISP's run UPS's to not only keep things going but to also clean up the dirty eskom feed. And spikes are massive after load shedding.
Surge protectors are so cheap and they work well - i have never lost anything ever. Close friend of mine has lost computers, tvs, monitors, routers,fridges all due to load shedding and bad winter rainfalls and still he refuses to buy surge protectors.

Yup, just make sure it is a Deep Cycle battery

Those batteries, last time I had one, were deep cycle..

Excellent.
Normal lead acids are designed to cold crank an engine and then immediately start recharging the battery.
It's amazing how many people will use a car battery for external power and drain it to 10.5 volts. That just destroys a battery.
After load shedding last night with my entire lounge up and running I saw my batteries on my UPS were still at 25.4 volts (12.7 volts ea). They are normal truck batteries (not deep cycle)

I never used a car battery, besides they're even more expensive than good quality deep cycle batteries.
Most people don't know the charging curve of these batteries or the cut-off point, or what it means to float-charge.

Very true !
Luckily for me i scored these 2x105aH batteries for free. 2nd hand.

I got a 700VA UPS. Thinking this should be good to run my internet and networking gear through a load shedding shift

can u post a pic of the battery and how do u charge the battery.

 

[joker08]

Get the following:
1 x 12V "leisure battery" intended for caravans
1 x 10A charger from Centurion Systems (this beast is the boss)
Problem solved indefinitely

is there a link for the above ?

Connected straight into my UPS

No because these items are generally to the trade so you will have to go to someone like STAFIX, ACDC Dynamics, or use someone on Centurion's accredited installer list.

Also try Communica. They now around the corner from me in Paarden Eiland

Damn, so you work around the corner from me also..
Power cut incoming here soon I believe.. supposed to be 12:30 to 2:30

Cool
none today i think, only at 8pm if i remember.
We were off yesterday 12pm but luckily we have generators

Yeah yesterday was bad...
Totally messed up a server, we're still rebuilding DB tables on that box.

 

[joker08]

will visit communica, I have a battery that was pulled out of a garage door motor, will give that a go first.
and I have to ask them for a 10A charger ??
plan is to put everything in an enclosure and use it as a UPS for my modem and router. will it be able to charge and discharge automatically ?

Damn. Yeah there is some big ass stuff here in Paarden Eiland.
When power comes back on the surges and spikes are massive.

yup the bigger the battery the better as it will be depleted less than a smaller one thus you will get more life cycles from it.
Also check up the road at Deltec, i buy all my batteries there.
Go lead crystal, you wont regret it

A bit of a kludge but it gets the job done.

To explain how this works:
The lead acid battery in the alarm system is charged while its being used, and when the power goes bye bye then the battery is supplying the load- there is no switch-over.
The charger is usually strong enough to power the system and charge the battery.

This is why it can work for routers and such devices.

When it comes to an inverter, totally different animal. Inverter draws 100 times more current from the batteries than the actual charging current, so therefore you cannot build a charger big enough to run the inverter and simultaneously charge the batteries. This is why solar power can never really replace the utility for heavy loads such as dishwashers, kettles, etc..
