When should you change the car battery?

The clearest signs are that the engine turns slowly when starting, especially in the cold, that the battery warning light comes on, that the Start-Stop stops working or that the resting voltage drops below 12.4 V. If the battery is more than four or five years old, it is worth checking it before winter.

Before changing it, check that it is not a charging problem: if after a full charge it discharges again within a few days, the battery has lost capacity.

How long does a battery last?

A car battery lasts four to six years in normal use. Very short trips, extreme heat and leaving the car parked for weeks without starting it shorten its life. A motorcycle battery usually lasts two to four years, and a well looked-after deep-cycle battery withstands hundreds or thousands of cycles depending on the technology.

LiFePO4 lithium batteries last the longest: they exceed 2,000 cycles and hardly discharge at rest.

How much does a car battery cost?

At bateriasonline.es car batteries start at €34.69 with VAT. A conventional 60 to 77 Ah battery for an average car costs between 60 and 85 euros: the 60 Ah Varta D24 is €63.37, the 77 Ah Exide EA770 €63.72 and the 74 Ah Varta E11 €73.17.

Start-Stop batteries cost more because they are reinforced: an EFB such as the Exide EL700 is €82.63 and an AGM such as the 70 Ah Varta A7 €122.95. Shipping is added to that price, and you see it in the cart before you pay.

Can I change the battery myself?

In most cars, yes. Disconnect the negative terminal first and then the positive, remove the hold-down clamp, place the new one in the same position and connect the positive first and then the negative. Tighten the terminals without forcing them.

In cars with energy management, common since 2010, the new battery has to be registered in the control unit so it adjusts charging. If you prefer not to do it yourself, in 7 provinces we install it at your home for €96.80.

Which battery does a motorcycle take?

Motorcycles use 12 V batteries from 3 to 30 Ah, with standard formats such as YTX, YTZ, YB or YT, which indicate dimensions and polarity. The reference is usually printed on the battery you have: a YTX14-BS is replaced by another YTX14-BS of any brand.

Sealed AGM batteries come ready to fit; lithium ones weigh much less and need a charger with a lithium mode.

Which battery do I need for a motorhome or a solar system?

For the living area of a motorhome and for off-grid photovoltaics you need a deep-cycle battery, not a starter battery. AGM and gel batteries from Trojan, Fullriver, Exide or Varta Professional withstand slow discharges night after night.

To calculate the capacity, add up the daily consumption in Ah and size the bank so it is not discharged below 50%. LiFePO4 lithium batteries let you use almost all their capacity.
