Choosing the correct battery for the job

A lots been written about start-stop batteries, and now that nearly two thirds (60 per cent) of the cars sold in Europe now have either start-stop or energy recuperation technology or both, these cars are now finding themselves with the second user and it’s important we understand the only choice is either AGM or EFB and that a Standard Flooded is not an option.

Enhanced Flooded Batteries (EFB) is an enhanced version of standard wet-flooded technology, the primary benefits of EFB technology are improved charge acceptance and greater cyclic durability when operating in a reduced state of charge (typical of Stop Start applications). As an approximation, EFB batteries will provide 85,000 engine starts, compared to 30,000 starts from standard flooded battery.

Absorbent Glass Mat (AGM) benefit from the inclusion of unique design features not found in wet-flooded batteries. These include glass mat separators, recombinant lid technology and higher pack pressures to facilitate improved cyclic lifespan, they are better suited to meeting the demands of higher specification vehicles that include one or more of the following technologies: Start Stop, Regenerative Braking and Passive Boost.

The absorbent glass mat gives a number of key benefits to the design of the lead acid battery:

Within normal operating conditions, the use of the individual cell valve design and glass mat plate separation ensures gas recombination occurs and ensures that no water is lost therefore negating the need for electrolyte reservoirs and freeing the user from maintenance.

One way venting system providing partial pressure in each cell ensuring 100% leak proof and safe handling.

The acid absorption of the glass mat means that the battery packs can be operated under higher pressures than conventional flooded batteries this has benefits including significantly prolonging battery cycle durability by minimising paste shedding.

The increased pack pressures of the AGM battery increase the batteries resistance to vibration.

More reaction surface area ensuring higher starting capacity within the same footprint as conventional Flooded batteries.
Understandably, drivers are tempted to choose batteries by the variance in price, the price differentials of the regular flooded battery, EFB and start-stop batteries is considerable.

It is ESSENTIAL to replace batteries with like-for-like technology that’s AGM or EFB, the reality is starting an engine is the most demanding thing that the battery will do, to do this repeatedly during a succession of short, low-speed drives requires a heavier duty AGM or EFB type and they are more expensive.

Fact If a standard flooded battery is fitted to a Start-Stop vehicle, it will definitely fail and failure could be within 2-4 months of installation.
This type of battery failure will lead to loss of vehicle functions (including Start-Stop).

Noticed this depot/branch by chance while going to get a secondhand battery from a breaker. Man who served us had a scientific air about him and sold us a Yuasa battery for 48pounds. This would have cost 97pounds at Halfords or 120?pounds at Kwikfit.
Thankyou, very pleased not to have had to take a gamble off the internet and will tell people about you.

We purchased a battery for our car on Saturday morning from your Exeter Branch.
We thought the person that served us was extremely
professional and very pleasant. We would have no hesitation in recommending your company to others.
Thank you for a very nice experience

Great service, Bristol Branch, they replaced my battery on my Skoda superb estate which was just over 3 years old (2011) and just out of manufacturer warrenty. A better battery than fitted and about £60 cheaper than Skoda. The gentleman that did, I think his name was Seb, it knew everything aboout batteries and re-programmed the battery to my car which I did not know that was even needed as the ECU needs to compensate for the charging rate the older the battery is. No radio codes were lost dispite one dealer and the AA saying it would. Also went through all checks to make sure all windows were working, even headlamp cornering facility worked as replacing batttery needed a number of things re-setting. So thanks for the great service and I will we back if I need anything battery related

I bought a new YUASA battery for my bike. One assistant tested the existing one to ensure it was fatally sulphated and not recoverable (punishment for not keeping it on trickle all winter). The battery stands upright so the other very helpful assistant sold me one he himself prepared - adding battery acid to the mat - which saved spills, my nerves,  and money on the full-fat factory prepared one. Always helpful, astonishing variety of sizes, cells, chargers, and even solar.

Excellent customer service.  Saved £90 refurbing a Powabike battery.  Highly recommend.

Bought a new battery for my FZR600 and they pre charged it for me and even helped me install it. I highly recommend anyone to go there for there battery needs, the service is excellent and the staff are extremely helpful.

Bought a battery for my motorbike and it was a good £20 cheaper for the exact same battery from Halfords. Also they filled up the battery and charged it for me wile i popped into town for a hour. To top all this off was the great customer service,very happy and will definitely returning again,highly recommended.

I had a problem with starting my 1935 Austin 7. Visited the Truro branch and the staff easily identified a defective battery. Supplied a more efficient Exide product and today checked out my C-Tec Charger. Good old fashioned service with customer care and advice being uppermost in their in their minds. Thank you and highly recommend this Branch.
