tunze 6101 battery backup options

[The Saltman]

Roger,

I'm looking into purchasing a battery backup for my 210 that has 4 tunze 6101's. I understand I will need to purchase the connector for these also. I'm looking for a battery that will supply 1 of the tunze 6101's for at least 24 hours. What type of battery will I need for this. What is your recommendation. If I could pick up this battery type locally it would be a plus.

Get one of those bad boys. You wont find a 40amp/hr + inverter for any cheaper then that.

well maybe youll find it at a different store for cheaper, but the link is just to show yah what model it is.

You just need a 6105.50 and a battery and a charger, the 6101 is DC so no inverter is needed. The pump will use about 10W at 12V so roughly 1Amp, a 25 Amp hr Gel Cell, like the type that are used in an alarm for back up or a Power Wheels toy should do the job. You can buy these at a Batteries Plus as well as a small trickle charger for it. FWIW, in an emergency you can use a 12V lantern battery or 2 6V lantern batteries wired in series and this will run the pump for about 2-3hrs.

Would this be a good one with a charger? This one has terminals. Do I need one without terminals?

Something more like this, http://www.batteriesplus.com/pc-326...ttery w- Nut Bolt Terminal - WKA12-26NB.aspx

Ideally you would use solderless terminals, just the basic male slide on terminals, preferably the covered type. The wiring is largely DIY so your options are open

Would this charger work for the battery you recommended?

 

[rvitko]

Yes.

That costs the same as my suggection, but its only a 26AHR battery. The item I listed has a 12v DC out as well and is 40amphr.

sorry if I seemed a little confused here. With a dc current source and using the safety connector, can I just plug into the power source you are suggesting? Also, is it rechargable? The other recommended one(charger) I would have to wire the terminals?

 

[jezzeaepi]

I am not familiar with the use of the DC safety conectors sorry =\

I just leave my 6101 plugged into the back of it 24/7(the unit plugs in tot he wall to keep charged and run your items when the power is on). If the power ever shuts off, this autmatically kicks on and the pump runs uninterupted.

With the inverter you lose efficiency you are kicking 12V DC to 120V AC and back down to 24V DC it is less efficient it works but my guestimate is the 40AH battery would last less time than the 26AH but this would also be because the pump is using the full 24V instead of the 12V limit of a single 12V battery, basically instead of 1A you are using 1.5A and you are taking the losses of the inverter and transformer. The main advantage of the safety connector is versatility, if you were so inclined the pump could also be solar powered using this connector and if your battery goes dead, assuming any hardware store or drugstore is open which is likely in any non apocolypse scenario, you can walk in and buy a couple lantern batteries and keep going a bit longer. It really is the way to go unless you are dead set against having to do some basic wiring.
