Today I made a battery backup for my Tunze 6095 and I have taken some pictures to help you make your own :D

You will need:

- A controllable Tunze pump
- Tunze safety connector 6105.5000
- Small spanner
- Crimping tool
- 12V 18ah sealed lead acid battery
- 12V 1A trickle charger
- Little yellow fittings with metal ring on the end (yes thats their technical name :confused: )

You can buy the battery, charger and the additional items all from Jaycar.

1. Unscrew the weird attachment that comes with the Tunze safety adaptor, it should look like this

2. Now that connection is gone, you have two exposed wires. Slide the exposed wire into the little yellow fittings and crush it with the crimping tool so it is nice and tight.

3. Now attach the little ring to the battery. The red wire goes to the positive terminal and the black wire to the negative terminal. Tighten the bolt with a small spanner.

4. Now attach the charger. The red clip goes to the positive terminal and the black clip to the negative terminal.

Now we are good to go!! That was easy, took about 10 minutes. Total cost was $112.60 and another $60 for the safety connector. A small price to pay for some additional peace of mind :)

Nice! How long do you think it will last?

 

[Craig]

I think the pump runs on 800mA, so technically it should last for 22.5 hours. I will let it run on the battery to get an exact number :)

Should be plenty of time if anything happens hopefully. I took the easy way and got a vortech backup with the tunze safety connector second hand for around the same price yours cost.

When the tunze connector detects it is running on battery I think it halves the voltage so runs longer.

I KNOW ITS BEEN A LONG TIME HOW DID THIS GO?
