Fitting a new leisure battery, vent tube or not?

[ChrisD]

Hello Everyone.

 

I have a roller team 746 just over a year old and wish to change the existing AGM battery for a new Varta LFD 90. I can't find any info as regards whether this needs a vent tube although my instincts with lead/acid batteries says to fit one.

Are these truly maintenance free?

 

All suggestions greatly appreciated

 

Regards

Chris

The Varta/Bosch Powerframe battery uses unique technology that means they gas LESS than Gel or AGM.

 

All the evidence to support that here : http://www.aandncaravanservices.co.uk/battery-technology.php

 

The web page contains lots of information from both the Varta and Bosch websites.

 

We have charged one at artificially high volts to simulate a charger malfunction, and it still didn't gas.

The exact same issue was discussed here in February 2018

Thank you Allan and Derek.

 

Very informative page Allan, interesting reading. You indeed have a wealth of knowledge.

 

Oh dear Derek what short memories we have.

 

Vented it is in case those unlikely circumstances conspire like they did with the Titanic

 

Thanks again

Chris, I know a little bit, but I can't take all the credit. I am lucky I get quite a lot of info emailed to me and that goes on the web pages.

When I get it wrong they correct me.

 

I have recently been contacted by a techie from Yuasa, a real techno head who is in research, so hoping I will learn all sorts of 'insider stuff' and new technology.

 

We will see.
