Battery conditioner for XC90
Hi,
I'm not using my XC90 currently so looking for a battery conditioner to keep the battery in good health rather than having to run the car every few weeks etc. Is there a specific CTEK model to go for? or even an Aldi / Lidl equivalent that I can either leave connected to the car full time, or if that's not a good idea I can connect once a week overnight etc. Thanks |

Any intelligent battery charger / maintainer will be fine.
I use a CTEK MXS 5.0 model rated at 5A, which is fine for long term or overnight charging. Don't go for anything smaller than 5A though, otherwise you'll be waiting forever for the big battery to charge up. All the intelligent chargers drop down their charge rate once they estimate that the battery has reached full charged. PS: I just went to the garage to disconnect my CTEK MXS5.0 charger. My battery was at 60% charge before I connected the charger yesterday. It started charging at a rate of 14.5V, 5.0A, and today it had dropped the voltage to 13.9V to prevent overcharging. Looking at the graphed data my battery took from 1pm to midnight to reach 100%, that's 11 hours. 11 x 5 = 55 AH (approximately) put back into the 90AH battery. Very approximate as the charge rate varies during the charging cycle. I use a CTEK battery sense to monitor and record the battery voltage, allowing me to know when the battery is getting low so I can recharge accordingly.

If you have an existing "traditional" battery charger (i.e. a non intelligent 12v transformer and ammeter job) then invest a fiver in a plug in timer from screwfix and set it up so that it charges for 15 mins every day. Whilst an intelligent charger is preferable, this will do that job perfectly well.

In Germany ALDI always has a battery charger in it's end of October car week. I don't know about ALDI GB...
Would be this one: https://www.aldi-sued.de/de/p.auto-x...ladeger%C3%A4t I'm happy with it, beside the fact that these devices seem to attract every neighbour. Already bought four of it over the last years, still only have one in my garage. But all are working fine, despite not on my drives...

Thanks - have bought the CTEK 5.0.
I think I can then wire this into the battery points under the bonnet and leave the quick connector there. Can I then simply connect the CTEK device and leave it in auto to quietly manage the battery for me whilst I am not using the car ? |

Yes you can. Leave it on for a couple of days and then disconnect.
Volvo recommended charging it every two weeks when not using the car

Yes, exactly what I do with my Smart car that sits quietly in my garage in UK while I overwinter (6 months) with the Volvo in Spain.
I also do the same with the Harley. Both fire up immediately on my return. Cheers Dave |

These are battery eating monsters, if you leave them unconnected over the winter... The first years I thought it is the usual way, to buy a new battery every spring.
Turns out, batteries in Harleys can hold up to eight years, if you charge them properly over the winter (and summer). And I'm quite sure, this works for Volvos even better. What Harley do you have Dave?

Hi Paddy
It's a 2005 FLHTCSE2 Screamin' Eagle Electra Glide CVO 1680cc and "tweaked" to 100hp and 100 ftlbs torque. I've had it since late 2005 (bought as an insurance write-off, due to the price of the replacement painted parts) but amazingly still under warranty from the dealer, and built it back to my spec. I'm on 78,000 miles now and put all but 2,500 of those on myself. It's a keeper for sure. What's your preference? Cheers Dave |
