What Battery?

I've had some random starting issues the last couple of days where either the immobiliser hasn't disengaged or the truck fails to turn over. I noticed low voltage on the in-car meter the last time this happened and thought it might be time to replace the battery so that I could eliminate that from the equation.

Before I purchased a new one I'd like to explain that I started a new job 3 months ago which involves a 1 mile journey to and from work. I wondered if there is a battery more suitable to dealing with lots of short journeys?

Any thoughts?

Maybe have a chat with Barden's on Segensworth? Even if you don't buy it from them (they can be a bit dear on some things - even to the trade) you may get a better idea of what's available.

Hi Andy, You can buy a tester quite cheep or take your car to a battery dealer and they can do a test for you, you need to check the alternator and battery. That's assuming that there's not a fault elsewhere on the truck.

Took my old vw t5 battery to a place called Bristol Batteries and they said that the cold cranking test was very poor even though I had just fully charged the battery.

I've already checked the voltage at rest and under load by measuring the voltage across the terminals and it looks okay. But this only tells one side of the story so I'm going to replace the battery anyway. I've had the 4x4 for over 5 years and the battery hasn't been touched apart from the occasional trickle charge during the winter months (I've always done this).

It's a fair comment you make about the alternator Alex, but I'm pretty confident that it's outputting the correct voltage for charging as I can see whats happening as I switch all my electrical loads on and it's still reading healthy voltage.

As for any other problems, who knows? But I'll do the easy and relatively cheap things first.

Just gave them a ring, they weren't that helpful and suggested a battery that's suitable for start/stop technology. When he looked my truck up on their database there wasn't one suitable so suggested a 70amp Varta Blue with 630cca as a replacement. 80+ VAT

If I can't find anything more suitable I think I'm going to buy as big a capacity leisure battery as I can physically fit in the battery tray.

These have really good CCA's and the price is pretty good too.

Numax CXV27MF Sealed Leisure Battery 12V 100Ah 900MCA 500 Cycles XV27MF - Leisure Batteries - Numax Leisure Batteries
Numax CXV-X 1000 Amp - Leisure Batteries - Numax Leisure Batteries

What do you think?

When pricing up batteries in the past the price differs depending on the warrantee, once they sell you the battery they stick the correct sticker on for the type of warrantee/model you have purchased but its the same battery!

I always go for the cheapest 1 year option from a trade battery dealer

I didn't know that! That's a bit naughty!

I have never really looked at a warranty as a deciding factor in any purchase unless I'm buying blind.

I have a trade account due to the amount of batteries I had to buy for all the rusty toys my dad left behind, when I get a battery I go into the warehouse and choose it, they then take it to a bench to do some tests and then label it up.

When they tested my t5 battery they knew I had just charged it by testing it but under load it failed the test, a multi meter cannot do this test as I think it needs to be under load, you could try switching everything on (lights, stereo, heaters, heated windows) without the engine running and see how much the voltage drops.

I think with the engine running it should be about 14.5v but you can search for your car details on the net.

I don't think there is any point in getting a start stop battery as your alternator is made for the correct battery for your car.

When I was on the tools my van used to do about 1-2 miles between jobs about 10 per day and I had loads of equipment running off it, it always started after every day for three years before the van was replaced

Andy, personal experience last year when I stopped commuting 100 miles every day and dropped to 20, the battery low volt warning would come on almost every week. Had it tested for free at the local tyre and battery place and they told me it was simply the charging time on the drive to work not being long enough. Nothing wrong with the battery and I'd be wasting money by getting a new one. I'd really suggest getting it checked before buying a new one.

What do you think?

Sorry to hear that. I just gave them a call and prices to me:

the Varta 068 70ah (same as they quoted you) is 61.97 + vat
and Varta 069 74ah (slightly higher specification) is 66.09 + vat

Those batteries you listed look good. Only trouble with leisure batteries is that usually they're good for holding a charge, but not so great with cranking. However, those Numax batteries are good bits of kit and the crank on them looks good. I'll have a look and see how much they are to me, if you'd like? I could always drop it off, as we're both in Fareham.
