The Long 210H52 in practice
When not to choose it
If your car shuts the engine off at the lights, rule it out: Start-Stop demands EFB or AGM and a conventional battery lasts months in that duty. And never choose fewer Ah or A than the original.

Car battery Long 210H52 Starting Series 210Ah 12V
The Long 210H52 car battery is rated at 12 V, 210 Ah from the Starting Series range, and is designed for passenger cars with conventional starting, without a Start-Stop system. Measuring 518 × 276 × 242 mm, it is the direct replacement for cars fitted from the factory with a 210 Ah battery of this format.
- Designed to last several years under normal daily use.
- Stable voltage for the vehicle electronics (ECU, sensors, climate control).
- Low self-discharge: copes with long stops without losing charge.
- Original-equipment build quality without the dealership price.
What the Long 210H52 is for
The Long 210H52 covers the needs of passenger cars with conventional starting, without a Start-Stop system: reliable starting, stable voltage for the electronics and a service life of several years in daily use. Check that it matches your current battery in size and terminal position. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 39.90 kg.
Size, terminals and hold-down of the Long 210H52
It has external dimensions of 518 × 276 × 242 mm and weighs 39.90 kg. Before replacing it, measure your current battery tray: if all three dimensions and the terminal positions match, the swap is direct and needs no adapters.
What Long does differently
Long batteries combine large-scale production with ISO quality standards and a batch-to-batch consistency that has made them the de-facto standard in backup systems and electric mobility. We guarantee that every Long arrives new, charged and with the manufacturer's full warranty.
The Long 210H52 within the Starting Series range
Within the Long catalogue, the Starting Series series groups the references designed for this use. The 210H52 is the 210 Ah model of that family, with the same performance as its siblings in other sizes.
Care and maintenance
In normal daily use the alternator keeps the battery charged; if the car stands for weeks, a maintenance charge once a month prevents deep discharge. Keep the terminals clean and tight, and check that the resting voltage does not drop below 12.4 V: below that it is time to recharge.
Warranty and coverage
The Long 210H52 comes with the manufacturer's official warranty against manufacturing defects; the exact period is stated in the brand's conditions. If it fails through a defect within the period, we replace it free of charge.
Shipping, delivery and returns
Order before 6:00 pm with stock available and it leaves today: mainland Spain and Portugal receive it in 24-48 working hours, the islands and the rest of the EU in 3 to 5 days. You have 14 days to return it if it has not been installed, with free collection on the mainland, and shipment tracking by email.

Frequently asked questions
How do I change this battery step by step?
Our blog guide covers it in detail; if the owner's handbook describes a different procedure, follow the manufacturer. On most cars it is a 15-30 minute job needing only a 10 mm spanner (up to twice as long when the battery is under a seat or in the boot). What matters most is the terminal order: removing, negative (−) before positive (+); refitting, positive (+) before negative (−). In between, with the engine off and the key out, release the clamp and fit the new battery the same way round as the original (polarity).
What is the service life of the 210H52 model?
As a guide, you can expect the Long 210H52 to last 4 to 7 years in regular use (depends on technology and climate), although the real figure may be higher or lower. Many factors play a part: how it is used (lots of short trips, for example), temperature (cold makes every start harder and intense heat evaporates the electrolyte), the condition of the alternator and charging system, power drawn with the engine off and maintenance, as well as the type of car and whether it has Start-Stop.
What are the dimensions of the Long 210H52 battery?
Before buying, measure the space in your car: one extra millimetre can stop the hold-down clamp from closing. The Long 210H52 takes up 518×276×242 mm (length, width and height, terminals included).
Will the Long 210H52 battery fit my car?
For your own vehicle: type your number plate into the finder (DGT/DVLA/KBA identify model and engine), check the "Compatible vehicles" tab below, listing vehicles verified by our technical team, or message us on WhatsApp with make, model, engine and year; we reply during business hours (Mon–Fri 10:00–13:30 and 16:30–18:00 (Spanish time, CET)). The car manufacturer's specifications always take priority over our tables.
What are the equivalents of the 210H52 model?
A direct equivalent needs what this 210H52 offers: 518×276×242 mm, the same Ah and CCA. See the "Equivalents" section of this page for the recommended options at the same performance level. Mind the technology: in Start-Stop cars an EFB is not swapped for a conventional battery.
