Pop round the Chemist's and pick up a sleeve of 9V square batteries and then wire them in series......small enough to fit them in doors, behind the facia, up Nic's lunch bucket......or in various and sundry corners of the interior...might not need any CAD either. JUS SAYIN'

To achieve the 100+ Amps of current from 9v batteries would probably results in a bigger / heavier setup than the normal battery.
GrayRaceCat said
May 24, 2017
My math may be suspect but...
It would have to be 9v or 18v as 12v/9v= 1.3 The standard 9v battery is nominal 9v @ 400mAh (per Wikipedia), that said it would take 250 in parallel to achieve 100Ah @ 9v and 500, (two 250 packs in series) for 100Ah @ 18v As to the weight, data varies from 45g to 100g, at 45g the 9v pack would be 11.2k or 24.64lb, the 18v pack would be 22.4k or 49.28lb Per www.chem.hawaii.edu/uham/bat.html , most small car batteries are 45Ah, I don't know what that would be in CCA.
So, 500 9v batteries for 18v @ 100Ah and 22.4k / 49.28lb, $1.25ea = $625 US, 482.35 British Pounds. Expensive, heavy, odd voltage, and unknown cranking capacity.
It might be more readily achievable with 18650 Lithium Cobalt Oxide (LiCoO2) cells (Samsung 26F).
18650 cell is nominal 3.7v @ 2600mAh (max discharge 5.2A) 47g, 18.4mm Dia x 65mm L. ($3.10 each for 100+ qty)
40 x 2600mAh = 104Ah @ 3.7v, 4 x 3.7v = 14.8v, gives us 4 packs of 40 or 160 cells total,
each pack would be roughly W=73.6mm(2.9in) x L=183.6mm(7.62in) x H=65mm(2.55in) + wiring, might fit all four under the seats!
160 cells gives us 14.8v @ 104Ah (max discharge 208A), 7.52k/16.54lb, $496 US, 382.54 British Pounds.
Expensive, light, standard voltage, better idea of cranking capacity.
I'm done now! That was fun!

Great calculations, I think for car batteries, the amount of energy (normally measured in Ampere Hour) is normally not the major concern. The big current draw for the very short period of time used by the starter motor is normally the major design concern. That is also why most of the car batteries in none-electric cars are not deep cycle batteries, and battery life can be affected if drained too much.
Assuming a 9v battery can discharge at 500mA, this would still require around 200 9v batteries, it is still going to be quite heavy.
andsetinn said
Jun 5, 2017
Nice calculations but 9 cell batteries only give about 1/2 amp forcing you to use a lot of them for starting the car and they are not rechargeable. A better bet in my opinion would be the 18650 cell, 3 volts under 35 amp load. You put them in series of 4 and parallel connect 5-10 series or so and you have light powerful and compact battery. You can also buy readymade Lithium batteries for cars that would work fine.
As noted the 9v alkaline batteries are not rechargeable. Rechargeable 9v batteries would add considerable cost.
Plus the 18650's would require some sort of Battery Management System (BMS) to maintain balance between and avoid damage to the cells.
It looks like the best option might be an automotive AGM type battery.

Jun 5, 2017
Of course this is all in theory. :)
I am certain you could get away with 20 x high capacity 18650 cells, and do not need 160. 4 in series and 5 series in parallel. The official discharge numbers for 18650 are usually continuous discharge to empty and are shown in C or Capacity. Higher capacity equals higher discharge in amperes. Momentary discharge can be very high, 10 second discharge can usually be 10 C or more, especially if cooling is used.
For balancing. The cells will never get empty under normal use, maximum current draw is when starting which only takes few seconds. So they don't need complicated balancing system. In the cells connected in series one cell cannot get more charging current than the others so they should stay balanced, if one gets slightly overcharged it will release energy in form of heat. The parallel connection is trickier but they all get the same charging voltage so they should also stay balanced. Since the maximum voltage of each 4 cells in series is much higher than the 14.4 coming from most alternators, and minimum voltage is much lower, you are very unlikely to overcharge the battery or a single cell within it.
In case someone is not sure of the terminology. A cell is a single unit that converts chemical energy to electrical energy. A battery is made of cells connected together. The 12 volt battery in most cars is made from 6 x 2 volt cells. A 1.5 volt alkaline AA battery is misnamed, it is actually a cell. The 9 volt battery is made from 6 x 1.5 volt cells.
If the 18650 cells are deemed unsuitable, how many AA rechargeable cells do you need to start Binky. :)

11 x 1.2v = 13.2v, 44 x 2300 mAh = 101.2 Ah, 484 AA cells = 13.2vdc @ 101.2Ah, 484 x $3.25 = $1573.00 !!

You don't actually need a starter motor, just jack up and spin the wheels or point it downhill. The battery then becomes very small, just holding a teeny bit of charge to last while stationary. What could possibly go wrong?

I think space is the major concern here rather than weight or capacity. Thus super capacitors might even be a worse choice than a reduced capacity conventional battery.
Lithium batteries requires complicated protection and charging circuits which takes up space, but that can be installed in 2 locations, which makes them still a possibility.
My bet is still a conventional lead acid battery designed for a modern small vehicle, it offers not only a simpler installation, but also caters to the huge current needed by the starter motor.

Up under the front wheel arch... between Wheel and Door Hinges.. TOP...
and make a inner protective guard.. from road bullets..(rocks)
There is a lot of space up there which cannot be accessed with a fix front mini.. but a removable front .. you have a TARDIS.
Drivers Side..so its easy to fit battery cut off switch, in reach of driver, which is also very close to the actual battery terminal. Very important for race cars.. or cars with a lot of custom wiring.
Also MINI-mal voltage drop as it's closer to the starter motor...
LiPo Small Light Tuff.. Only hassle .. the cold weather.. Lithium batteries drop performance in cold weather.. like heaps.. UK = :(
But then again.. A hot cup of Tea ( or you have already drunk the tea - full bladder ) poured over it would sort it... and once the engine started.. the heat from the engine would improve things.
Seriously the GRUNT these small batteries is amazing.. We use them a lot in Karting.. then again Richard would know that ;)
P.S. LiPo.. 2 types.. ( chemistry wise ) .. one that goes BANG-FIRE-BURN..(cheap - RC Model stuff and Chinese Segway copies ) = NO / and ones that don't... = YES
P.S.S The reason I suggest this.. is I too am look to install a Battery .. and Just want something to COPY .. :)
Win / Win MY IDEA ( or NICKs - he just hasn't realised yet ) ../ and The boys amazing Fabrication skills
P.S.S.S Trouble is ... If I asked for the CAD drawings.. it would have to be FAXED.. and would need to cut it out.

Seriously the GRUNT these small batteries is amazing.. We use them a lot in Karting.. then again Richard would know that ;)
P.S. LiPo.. 2 types.. ( chemistry wise ) .. one that goes BANG-FIRE-BURN..(cheap - RC Model stuff and Chinese Segway copies ) = NO / and ones that don't... = YES
P.S.S The reason I suggest this.. is I too am look to install a Battery .. and Just want something to COPY .. :)
Win / Win MY IDEA ( or NICKs - he just hasn't realised yet ) ../ and The boys amazing Fabrication skills
P.S.S.S Trouble is ... If I asked for the CAD drawings.. it would have to be FAXED.. and would need to cut it out.
