Battery Confusion - help needed please

Hi,

 

My car (J-Spec) has been at work for the last 10 days or so as I've been working away. The last time I drove it, it was a bit sluggish starting. Well now the battery is totally dead :(

 

I've bought a 'HCB005' from Halfrauds and just tried to fit it, but the battery terminals on the car are too narrow for the lugs on the battery. Anyone else with J-Spec found this?????

 

Have I bought the wrong one? How do I get this to fit?

 

Please advise as I need (and want) to get it moved

 

cheers

I had this too,

 

Japanese Domestic cars have what is referred to as skinny post batteries, Halfords only sell batteries for the UK domestic market, which have the fat terminals.

 

You have two options, replace the battery with one that has skinny posts (from a specialist Car electronics motor factors) or replace the clamps with ones that accept the larger UK terminals.

 

I went with replacing the clamps, but I had difficulties trying to use halfords screw type clamps, and in the end went for some others, but had difficulty finding them too.

 

Good luck

 

Mike

Surely you should be able to get a converter clamp so you put the narrow J-Spec terminal over a post on the clamp then put the larger UK-Spec terminal on the converter clamp onto the new battery?? :shrug:

 

Would be easier and safer than cutting and recrimping the original cables...

Just did mine this weekend. Since you have a TT, you will have problems moving the cables far enough to fit, because of the PAS reservoir location.

 

Keep the battery you just bought and get a negative terminal from Halfords. You will need to take your dremmel to your Toyota negative clamp - cut off the loop, and all edges, making it into a flat bladed spade connector with a hole through it. Enlarge the hole enough to fit the screw for the new clamp through.

 

The positive clamp is more trouble. Because of the PAS reservoir, you can't twist the cables far enough to do the same as for the negative, so you need to buy the UK spec terminal clamp (about £14). I can get you the part number this evening, unless someone can jump in here. Don't bother trying to bodge it, because it'll only come back and bite you.

 

Oh yeah, the HCB005 battery is also about 16 cms across, but the JSpec batteries are about 12 cms across, so you'll need to either cut your clamp, or buy the proper one.

Cheers Ark,

 

A work colleague knows someone who runs an automotive electrical outfit, so is ringing him to see what he suggests. I was thinking the same as your suggestion for the negative, hadn't considered that the cables may not be long enough, or that the clamp may no longer fit!!!

 

Am going to charge battery tonight to see if that allows me to get the car home tomorrow. Probably have problems with the immobiliser and alarm too !!
