Hi all, Just passing on a tip passed on. Did you know that at standard "063" 12v battery will fit in a MGB battery bin? Well it does, and if a heavy duty (mid range) battery is used it has plenty of cranking power to flip a B. I have just replaced my first 063 (after 5years of service), which I think is reasonable. The clock, and a lack of running over the last winter finally did for the original, and I don't think a pair of 6v would have done any better. The extra advantage is will the purchase of a single battery bin from MGOC, you have a nice spares box!. 12v Batt, and electronic 123 Ignition.. If the batt can turn it over once, it will fire!!

Where did you get it, as you said Halfords dont stock it?

Umm, Halfrods does do them but at £80...
I got my nice Varta from Motor Parts Direct (Bicester Trading Estate).
If you want one I can happily pick one up.

taken from the B register web site www.mgb-register.org MGB 6 Volt Batteries A frequently asked question is "can I fit a modern 12Volt Battery in place of the two 6 volt Batteries fitted to many MGB's". The answer is Yes a 12 volt Type 063 Battery will fit nicely into one of the two 6 Volt positions leaving the other position available for fitting a useful tool/spares box , the only mod required is to replace the existing battery strap with a couple of large cable ties or similar. Incidentally the Type 063 Battery actually has a better cranking performance than the original two 6 Volt Batteries.

Took the plunge and have finally done it. The cost for the Varta was £43.74 from Motor Parts Direct in Bicester as you said, but it is a tight squeeze to get it in the bin, and that's without a plastic liner! Started easily too, so we'll see how it goes over the summer.

You have to cut the lugs off the bottom to get it in. How do you secure it then as there is no longer room for the hook bolts.

Guys - Use a type 202 battery instead of the 063. The 202 does not need lug-shaving and the original J Bolts and hold down bar can be re-used. The existing Positive cable from the engine bay will reach the 'new' + terminal post provided the 12v battery is placed in the (UK) driver's-side battery bin with the terminal posts toward the front of the car. Drill a 1/4 inch hole at the top of the bin-bracket on the wheel side of the bin and fit a new earth strap/cable, making sure the connection is to bare metal and tight. Remove the clamps from either end of the redundant link cable and tie it off out of the way. Smear the terminals and the earth connection to the body work with Vaseline. Remove the original earth strap from the other side of the car and replace the bolt into its hole and smear it with grease. Retain the spare J-Bolts and hold down bar and the rubbers from the bottom of the other (now spare) bin, just in case (unlikely) anyone wants to re-instate the original 2x6 volt system.

Ooops - in my post a few minutes back I should have clarified, the mention of 'The existing Positive cable from the engine bay' is, of course, in respect of a Negative Earth Car. Also the earth connection to the bodywork should be with a fine threaded nut, bolt and washer of suitable size. Finally, while the existing J-Bolts can definitely be re-used, the nuts will almost certainly bottom-out on their threads as the 202 is seemingly not as tall as the OEM 6 volt battery. Simple fix for that is to slip an over-sized nut over the threads to effectively pack-out each j-bolt thread a bit, enabling the original nuts to tighten-up.

I have plastic battery boxes fitted to my 1964 roadster, will I still be able to use a 063 and 202 batteries better still will I be able to lift the battery out at any time in the future?
regards
Shaun

Hi Shaun,
Battery boxes should not present a problem, although some modification may be needed to the height of the box in order to accommodate the shorter type 202 battery on the original j-bolts and clamps. Both & 063 and 202 (and I believe most new) batteries have pop up handles so that lifting one out is easy. The 'spare' bin makes a useful storage space as rustynuts pointed out above. I think you will struggle with a type 063 if you use a battery box, it fits but it's tight, and you may need a different hold-down.

Just looking at the Halfords site there are a few variations of the 063 acid, calcium and there is also a Silver (HSB012) that look like it could fit in the space . The Silver (being new tech) appears to have a higher startup power. If we're to ignore the price I would assume the best option would be the Silver due to the start up power. However, I read this in wikipedia: "Silver calcium batteries generally require more charging voltage (14.4 to 14.8 V) and may not be functional in older vehicles because their power generating systems (alternators) give lower voltages than those of modern vehicles. This also may occur with static chargers, some of which fail to charge these batteries."So, for the sake of compatibility would it be best to go with the acid HB063 with the lower start up power and the 14.1 charging voltage (the calcium also has a 14.4 charging voltage)? if that's the case other than size there doesn't appear to be any difference on startup power between the acid acid HB063 and the HB202, both will fit. Advice most welcome. I'm not clued up on batteries at all.
