Thread: 14V-13.8V-13.6V- - - -

Must be the Continuum Transfunctioner Pedro


Cheers Ean

Maybe Graham hit it with a big hammer,,,
I know I'd like too-

When you say you had low voltage, how low we talking?

I would think above 14V constantly is a bit high if you battery is in good nick.

I hope you have a calcium battery or you'll cook a normal lead acid above 14V.

Bollocks , ideal between 13.7 - 14.2v . you won't start to cook a battery until around mid to high 14 .
Pedro , same battery ?.

hmm, my charging voltage is about 14.3-14.5 volts

yep calcium battery,, as all D2 batteries should be,,
just back from a 30min drive in the rain, so wipers and headlights, lowest V seen was 13.9 which happened as soon as the lights were switched on
still happy.

Well it's all in the temperature and where you live. You want to stay below the gassing voltage of the battery for any length of time. It's the quickest way to shorten the life of a sealed battery. Which I would think we all have, bar a few.

Maintenance Free Batteries? Or "you can't do Maintenance Batteries! Take note of the vent in your maintenance free battery! It's not there for looks. If the charging voltage exceeds the gassing voltage the battery will vent the electrolyte in vapour and with no way for you to replenish it the battery will have a reduced service life. A normal wet cell battery that you can maintain will more often than not last longer.

Where I live up in Cairns with the temp it the 30s most of the time my gassing voltage is 14v. I haven't checked but the battery temp on a drive would be around 50deg I would think, so now the gassing voltage drops to 13.8. Down south your right your gassing voltage at 20deg is 14.5 so you would be fine charging in the low 14s as long as the battery stays cool. BUT keep an eye on your voltage in the summer time.

So my Disco immediately after starting will hit 14.1 then drops to a steady 13.7 within a few min. PERFECT!

Good one Pedro yes EVERY Disco (and Euro cars) should have a calcium battery But I know some pretty cheap bastards that will stick in anything that fits and complain why there cheap arse battery only lasted a year.

So Bollocks? it's all in your perspective

Pedro question, where's the golden triangle?

i dont agree.
batteries arnt that smart.
