Small battery
What sort of amp hour battery do i need to turn over a bike carbed 2.1 pinto, currently 9.7 to 1 comp but will be 10.7 to one in the near future. I
want a small one but not so small to be useless.

A fiat cinquecento starts my 2.0L zetec on bike carbs without any problems. I bought a "calcium type" battery because they were supposed
to be better. Other option is a very small racing battery from the likes of odyssey or varley.

I have a Red Top 25 battery that turns over a 1.4 k series. It is rated at 680 amps cranking. The original rover battery has only 380 amps.

And I've one of the same starting my zetec. Does so first turn of the key, every time.

I forget where I bought it now (about a year ago) but the smaller ones in the range are plenty big enough for your application - I will find a link
....
Here you go -
Redtops
Odyssey
I was sceptical about these tiny batteries until I started using them - my PC680 is used in the Ultima and easily turns over the biggest V8. It
certainly has no trouble with my V6 
Completely sealed, you can mount them any way up you want to! Best battery I ever bought

Try MNR, they have them listed on their website but no prices. Think they have a direct (family) relationship with the distributor.

These must be similar to the batteries in the portable jump start boxes. My cheap one managed to start my rangie for several days last winter and was
recharged by the cigarette lighter as I had lost the mains charger. Maybe locost solution is to use one of these, you can then unplug and take away as
an additional security measure! These turn up for around £20 in Makro, lidl, Aldi etc.

So would a red top 20 be up to the job on a pinto then?
I am also after a battery for mine. And for the extra it will cost to fit a decent one i might as well....

You could probably start two Pintos at the same time with a Redtop 20

take a look at the odyssey batteries on here; seems like a good price to me but then
what do I know?
not sure if it includes VAT and not been able to find post/apcking.

No, those are gel batteries like the types used for backup in house burglar alarms and computer UPS systems. They are only rated at 17-18Ah, and to
be honest using them to jump start cars is totaly abusing them, though they seem to last reasonably well (my first died after a year but replacement
still ok). They have very specific charging requirements, an alternator would kill them very quickly.

MikeRJ - you are correct about the Gel batteries. Google, my trusty littel friend, tells me there is a new type of Gel Battery, so if your cheapo
jumpstarting box has one, you are laughing
quote:
AGM, or Absorbed Glass Mat Batteries
A newer type of sealed battery uses "Absorbed Glass Mats", or AGM between the plates. This is a very fine fiber Boron-Silicate glass mat.
These type of batteries have all the advantages of gelled, but can take much more abuse. We sell the Concorde (and Lifeline, made by Concorde) AGM
batteries. These are also called "starved electrolyte", as the mat is about 95% saturated rather than fully soaked. That also means that
they will not leak acid even if broken.
AGM batteries have several advantages over both gelled and flooded, at about the same cost as gelled:
Since all the electrolyte (acid) is contained in the glass mats, they cannot spill, even if broken. This also means that since they are non-hazardous,
the shipping costs are lower. In addition, since there is no liquid to freeze and expand, they are practically immune from freezing damage.
Nearly all AGM batteries are "recombinant" - what that means is that the Oxygen and Hydrogen recombine INSIDE the battery. These use gas
phase transfer of oxygen to the negative plates to recombine them back into water while charging and prevent the loss of water through electrolysis.
The recombining is typically 99+% efficient, so almost no water is lost.
The charging voltages are the same as for any standard battery - no need for any special adjustments or problems with incompatible chargers or charge
controls. And, since the internal resistance is extremely low, there is almost no heating of the battery even under heavy charge and discharge
currents. The Concorde (and most AGM) batteries have no charge or discharge current limits.

The AGM stuff has been around for years. They use them in the electrokarts in Europe. They withstand a lot of abuse. Recharge at some horrifically
high amperage in 20 mins. Swedish made, but the name has left my brain.
The plates are wound like a 'jam roll'. Very compact for their capacity.
Cheers,
Syd.

hi the redtop race ones need a trickel charger and are scrap after one full discharge they never fully recover.
The oddesey ones dont require a trickel charger and recover from full discharge really well both weigh simallar and are sealed type so can be mounted
lying down or stood up. Best price for the oddesey ones is the uk importers who are powervamp a quick google should find them i think last time i
heard a pc625 which is the one to have was £65 to the door.
cheers matt

Hi Matt,
I'm after an Odyssey for my locost - the only powervamp I can find are powervamp.com who seem to be manufacturers rather than importers... is
this the right company?
Cheers, Rob.

Hi well aint that strange as that is the same powervamp i have had a few of previously. However it seems that the hawker-oddesy.co.uk site says that
active-robot.com are the supliers in the uk now so i guess they have had a reshuffle of who supplies what.
Ps it lists the PC625 as fittment to a kwaka jet ski or sedoo and the price next day delivery is now ( crap cant remember exact ) but it was £85 ish
wich is a bit steep. Did some one say that MNR had some dealings whith them maybe try them for a price.
cheers matt

Remembered those batteries......
------------------------------------------------------
Optima Batteries
Demand more from your vehicle? Then get more from your battery. OPTIMA batteries are made for the extremes. If you have an extreme vehicle, you expect
high performance. Whether your vehicle is made to take the abuse of off-road driving or cranking out decibels, you need more from your battery. OPTIMA
batteries with patented SPIRALCELL® Technology deliver that performance. The extreme cranking power and deep cycle characteristic of this technology
coupled with its extreme resistance to vibration provides performance vehicles with the repetitive power they need in a spill-proof package.
------------------------------------------------------
These are excellent value, not particularly light or small, but extremely good.
Although, some of you will say they are not suitable for cars, as they are 'deep cycle'.
I know that they do some very small versions of these, but can't find them.
Cheers,
Syd.
