Flat Battery

[Peter 62]

Car has been parked in the street for a few weeks and the battery has gone flat.

Issue is that there is a car parked in front of it that has been there for months. There is only room for 1 car to drive up or down the road at a time, so if I parked alongside to jump start it I would block the road.

Would I be ok to park behind the car and jump start from that car direct onto the Volvo's battery (that is in the back under the floor)?

Am thinking it should be ok, but don't want to interfere/damage with any other electrics or electronics.

Do it late at night when nobody's around or take the battery out and charge it in the house....driving around with a flat battery won't charge it up to any degree....it will keep a good battery charged. Your battery should last a lot longer than a few weeks if it's in good shape....Maybe your alternator is struggling? Get it charged and get it tested .....SiRobb on youtube has done many V70 related battery/ charging videos....It's worth getting it sorted as there is never a good time for your car to not start.

I would agree that it's safer to remove the battery and fully charge it.

Then refit and start.

i would charge the battery insitu disconnect both leads from the battery before attaching the charger. do it over night to minimise any chance of causing a trip accident.

If the battery has been drained it will most likely need to be replaced

use a battery optimiser for best results with a completely discharged battery if no luck charging. tanya do a well priced yuasa battery with quick delivery.

I've jumped straight to / from the battery a few times without any noticeable negative effect

and as above I replaced the battery shortly thereafter as it was clearly an issue

the worst bit about it though really is you have to dismantle stuff to get at it, I always figured the under-bonnet points were more just a matter of convenience than anything else

I second taking it out and charging it in your home. It's easy to get out but it helps to have a socket extension to reach down do undo the bolt with the retaining plate. The arm across the top is easy.

Also it's very heavy and be careful with your back when pulling it up and out.

If it's losing charge again sooner rather than later don't mess about - buy another. I bought the Exide 019 and it's been great although I see prices have gone up.

Another thing I've done when I had an old battery from another car is take that to the car and jump start it that way - obviously you can do that if you take the battery out of the other car!

And I've also borrowed a battery pack on wheels from a local garage as I know them well.

Instead of a slave battery, I use a jump starter pack. Mine cost circa £30 from Aldi and is up to starting the 3.0L V6 petrol engine in Linda's Saab, so should cope with most Volvos.

It also has a small compressor (handy for pumping up bike tyres, etc.), plus 2 X 12V socket outlets and a USB socket, as well as work lights and emergency flashers. A very handy piece of kit! Just surprised no one has mentioned one before.

Regards, John.

I've found Tayna to be pretty much unbeatable....My Halfords trade card can also get some good deals....They are pretty easy to get; you don't have to be a Mechanic or have a garage but in the electro/ mechanical fields....it's all on line.
