Your questions answered
How much capacity and starting power does the Exide EF1251 offer?
The cranking figure is 850A, measured to the EN standard, and the capacity is 125Ah. If your engine is large or you live somewhere cold, choose the higher end of what your vehicle allows.
Can I connect several of these in series or parallel?
Yes, if they are identical. Two 12V units of 125Ah in series give double the voltage; in parallel they give double the capacity at 12V.
Which corner holds the positive post on the Exide EF1251?
Polarity: positive on the left-hand side. Face the long side with the posts nearest you to compare.
What kind of technology does the Exide EF1251 use?
Most smart chargers offer a lead-acid mode. Select it before charging to protect the battery.
Care tips for lead-acid batteries
Six cells of about two volts each make up a typical 12-volt battery. Tractors and trucks use robust flooded batteries. Avoid deep discharges, which encourage sulphation.
Same size and layout
If you prefer another make, these fit the same space with the same terminal side.

Fitting and everyday care
A tipper truck on a quarry run starts and stops all day in dust and heat. Check the battery box drain holes are clear on lorries. Renewing just half of a series pair rarely ends well.
