Evening all,

My car battery is on its last legs but am a little puzzled on what battery to get. Halfords website and euro car parts website list many but I need help.

The battery that's in there at the mo says 700 amps. But both websites say anything from a 600 to 780amp one will do. So my question is... Is it better to go for a battery with more amps?

The car is a 2006 Saab 93 1.9 tid

Thanks
 
The CA (cranking Amps) is what counts, If you can afford it get the most CA you can in the battery size that fits your car battery well.
Make sense ?
 
Thats what the 700Amps on the battery is (cranking amps or start up amps)

Replace it with 700Amps or more for a easy start. Diesels require more cranking amps so the more, the better in a sense. Once the engine is running, any battery will do the job as long as it holds charge and isn't being used extremely (like a stupid amount of car audio)
 
Cheapest....

Most Cranking amps..

Which is also a different design (AGM)
Comparison with flooded lead–acid cells
VRLA batteries offer several advantages compared with flooded lead–acid cells. The battery can be mounted in any position, since the valves only operate on overpressure faults. Since the battery system is designed to be recombinant and eliminate the emission of gases on overcharge, room ventilation requirements are reduced and no acid fume is emitted during normal operation. The volume of free electrolyte that could be released on damage to the case or venting is very small. There is no need (nor possibility) to check the level of electrolyte or to top up water lost due to electrolysis, reducing inspection and maintenance.[4]

Because of calcium added to its plates to reduce water loss, a sealed battery recharges much more slowly than a flooded lead acid battery.[5][6] Compared to flooded batteries, VRLA batteries are more sensitive to high temperature, and are more vulnerable to thermal run-away during abusive charging.[1] The electrolyte cannot be tested by hydrometer to diagnose improper charging, which can reduce battery life. [7][6]

AGM automobile batteries are typically about twice the price of flooded-cell batteries in a given BCI size group; gel batteries as much as five times greater. Less reliable than flooded lead acid [2]

Longer recharge time than flooded lead-acid

  • "Sealed" batteries cannot tolerate overcharging: overcharging leads to premature failure.
    Shorter useful life.

If I was you.... get the cheaper one. :D

You can get a Bosch battery from ECP for £63, they also have a £5 voucher if you hand over your old battery
 
battery mega store are good guys, fitted my last battery for free (saved me time) if you can see them in person they also take cash ;)
 
Pro tip order from euro car parts order delivered go through registration etc wait till you get to visa entry then close the browser within hours they send you an email with 30% off as a second chance did you forget something etc

Make sure you had registered
 
Indeed ;) Bosch S5 from ECP is £99.54 but they have 15% off batteries at the mo, and you can use macca's trick for even more ;)
 
I had noticed Varta batteries looked identical, the integrated carry handle on the top. So they are actually exactly the same then? Wonder who actually make them? Likely neither Bosch or Varta, lol!
 
Varta make them, pretty sure they also sell a range named Numax but these are budget batteries. Its not coincidence there exactly the same size, and specs for each equivelent battery.
