The MGF Register Forums

You got to love the TR5! Well, I do anyway - but then I love the MGC too - but it may be how you want to define what exactly makes a "Sports car" - a C-type Jaguar perhaps?

As for the Optima Red Top, if I am reading their Website correctly then it has a capacity of 50AH. The VARTA 075 has a Capacity of 61AH. I will test it again in Switzerland soon.

I also have to disagree. The TR2/3 was a truck. The TR4/5/6 were all much better cars to drive and the 7/8 were much better cars than the press gave them credit for.

As for batteries. If you exhaust a 50AH battery trying to start an MGF you have bigger problems than the battery!

I saw a TR8 blasting up the M1 this morning, I was at 70 as he went past!

Useful Battery info, thanks folks, until it veered off topic a tad

TR4a or a TR5 for me

Funny how threads do that...

BTW I am now trying to figure out what the smallest/lightest battery I can get away with...

This message thread turned up when I was looking to replace my battery which was playing up recently.
After some research, I found the battery I had in the car when I bought it was the wrong type - an 075 model.
I was unsure what to replace with but found Rimmer Bros had a useful listing for batteries. They were advertising the 027 model for cars with PAS, which mine is being a 2005 TF and the 075 for non PAS cars.
For anyone else wondering which battery to use, I went for the 027 AGM (Absorbed Glass Mat) batteries as these are apparently better (though admittedly a little more expensive) that wet cell if the car is not used regularly as a daily driver.
Tanya (www.tanya.co.uk) were by far the cheapest when I compared with the likes of Euro Car Parts. (2/3 to 1/2 the price of most of the common ones on offer.)
Hope someone finds this message useful

BTW, back to batteries. My 1.8MPi was fitted from new with the 075 battery (it had EPAS). I wonder whether during the "Project Drive" era (where as much cost as was humanly possible was removed from the TF) the decision was made to fit the smaller battery to all cars?

I had a Nissan Pulsar Turbo like that many years ago.
The factory design boffins bolted on the blower and a set of nice wheels and a boot lid spolier
and that was about it. Trouble was the battery kept going flat even though the still standard charging system
was working as designed.

I fixed their oversight with a battery of 50% more capacity and never had a problem again.
