Has anyone fitted and used one of these units, BCS BATTERY SAVERS. They make a lot of claims but?.

Do you have a specific brand in mind?
Who are "they"?

Someone will correct me if I'm wrong, but a battery current saver is just another name for a low voltage cutout device and yes, they do work.

A battery should not be taken below 30% of remaining capacity, or about 11.6 volts) otherwise it's life will be shortened dramatically.

A BCS therefore is almost mandatory unless you are continually monitoring current draw.

Some devices such as the Waeco compressor driven refrigerator have a built-in protection device. Other fridges such as the Engel will require the addition of an after market device.

Not a low voltage cut out device it alters the running times and frequency of the compressor supposed to be more efficient use of energy resulting in overall longer running time for the fridge.didnt notice any improvement with mine.Can send you my unit if you want it.

Thanks pepper2 however if it did not work for you?, a friend of mine suggested it, seems to indicate that it is used in boating circles. http://www.noelex.com/Sponsor/listings.htm#vgr
Wpould be good to learn more about the unit.

Ah yes. I did another search and found reference on the Nolex Web site.

Interesting indeed. I won't comment for or against the concept as I haven't seen any prior reference to the device, or tried ne myself.

One quote of interest from the advertising though was that almost all 12 volt refrigerators use a Danfloss commpressor and the BCS device was tested on these.

Well, my fridge doesn't use a Danfloss compressor, Duh!:-))

My fridge is also rated at 2.7 amps and does not cycle on and off any more than once every 15-20 minutes and so would have less impact methinks.

It reduces current consumption by letting the fridge contents warm up overnight. I use a fridge to keep my food at a safe temperature - ALL day.

I rate it similar to HiClone and Electronic Rust Protection.

Projecta do one with 10amp capacity.
I bought mine at K mart many years ago 5+. It is still going strong.

Philip,

I'm afraid I may have clouded the issue.

Like you I have a Projecta Low Voltage Cutout and they are very good, although I replaced the crappy plug & socket with Merit ones.

But reading up on this Battery Current Saver, it would appear it works on a separate principal by reducing the amount of on/off cycles per hour and therefore purportedly to save current draw as there is less load current being applied.

I'm open minded about the device claims, but as I alluded to above, my Engel doesn't cycle all that often and therefore there would be significantly less "savings" IMHO. I generally only need to run it on setting 1. I do not use mine as a freezer.

BB

I have ran one now for around six years, can't say it meets what is claimed but it gives me greater control over the fridge we run..

so it works a treat to me

Cheers

Richard
