Q 1. How do I choose the right battery for my vehicle or machine?
A. We are here to provide expert help with any product-related enquiry. WhatsApp 07754288583 or call 01926754100 to choose a battery matches your vehicle's specifications, including capacity, dimensions, and terminal type.

Confirm it is compatible with your model, offers the required power output and comes from a trusted brand with a reliable warranty.

Q 2. What's the difference between AGM, EFB and standard lead-acid batteries?
A. AGM, EFB and standard lead-acid batteries differ in construction, performance and suitability. Choosing correctly depends on vehicle technology, electrical demand, driving patterns and budget.

AGM (Absorbent Glass Mat)
- AGM batteries are sealed, spill-proof, with high cranking and fast recharge-ideal for start-stop, high-load systems. Maintenance-free; use AGM-compatible charging.
EFB (Enhanced Flooded Battery)
- EFB batteries upgrade flooded designs for better charge acceptance and cycling. Suited to mid-range start-stop cars and short trips; maintenance-free.
Standard Lead-Acid
- Standard lead-acid batteries are affordable and reliable for older or non-start-stop vehicles. Slower recharge, reduced vibration resistance and shorter lifespan.

Q 3. What does CCA (Cold Cranking Amps) mean?
A. CCA measures how well a battery can start an engine in cold conditions. The higher the CCA, the better the cold-start performance.

Q 4. How can I test the health of my battery?
A. Use a conductance or load tester to measure voltage, internal resistance, and starting performance. Inspect terminals, check for swelling or leaks, and confirm alternator charging voltage during operation.

Q 5. How can I prevent my battery from failing?
A. Keep terminals clean and tight, avoid deep discharges, fix parasitic drains, and ensure correct charging. Use a smart maintainer during storage and inspect mounting for excessive vibration or heat exposure.

Q 6. How often should I charge my battery if not in regular use?
A. Top up at least monthly, or maintain continuously with a smart charger. Storage, temperature, and standby loads affect intervals; verify state of charge with a voltmeter before use.

Q 7. Can I replace my old battery with a higher capacity one?
A. Yes-often you can. Upgrading to a higher-capacity battery can deliver longer reserve power and improved reliability. For a hassle-free upgrade and the right fit first time, shop with us at MachineRefurb.com - we'll help you choose the exact unit for your vehicle.

We keep trusted brands with fresh inventory and real warranties, make selection simple (share your vehicle reg, old battery code, or use-case), and provide fast, reliable fulfilment with friendly support from a team that truly knows batteries.

Q 8. How long should a battery last?
A.

Battery life depends on climate, usage, and how well it's charged. Batteries last longer when used regularly and kept properly charged. Extreme heat or cold, long periods of inactivity, and poor charging systems can shorten battery life. Leaving a battery discharged or fully draining it repeatedly will also reduce its lifespan.

AGM batteries typically last 3-5 years and are sealed, low-maintenance, and more reliable. They usually give warning signs, such as slower starting, before failing.
Conventional batteries usually last 2-3 years and require more maintenance, as water loss and poor charging can cause earlier failure.
Q 9. How should I maintain my Yuasa battery?
A.

Always keep the acid level between lower and upper lines on front side of the container (conventional type batteries).
Do not let the battery stand in a discharged condition.
Charge battery once a month.
Keep battery top clean, dry and free of dirt.
Clean battery terminals to prevent corrosion. Inspect vent tube, ensuring that it is not bent, twisted or clogged.
Protect the battery from strong impacts or shocks.

Q 10. What can cause a new battery to fail after installation?
A.

If a new battery becomes unserviceable within a few days or weeks after its installation, it may be due to one or more of the following reasons:

A faulty charging system
A short circuit in the electrical system
Battery terminals are dirty or not properly connected
Excessive ignition off drains or high parasitic drains
Electrical capacity of the battery is insufficient for size of the vehicle
The battery has been inadequately activated, dissipating its strength from the outset
The battery, after being filled with acid has been left too long without initial charging, and has been allowed to become sulfated

Q 11. How to determine whether or not my Yuasa battery has been fully charged?
A.

The following characteristics will tell you if a battery has been properly charged:

The specific gravity of the acid is over 1.275 (conventional type batteries only)
Maximum voltage output across battery terminals can be maintained at constant level for two hours
Open circuit voltage is stabilized at 12.7 volt or higher at 6.3 volt or higher for 6 volt batteries

Q 12. What is the normal charge rate for my Yuasa battery?
A. Naturally, batteries of different capacities require different charge rates. Generally, a battery should be charged at a slow charge rate of 1/10 its given 10 hr. capacity.

Q 13. What does "VRLA", "MF", "AGM", and "SLA" stand for?
A.

All 4 of these terms basically refer to the same type of battery. An example of this would be the Yuasa YTX series. These batteries are typically all black in color:

VRLA: Valve Regulated Lead Acid
MF: Maintenance-Free
AGM: Absorbed Glass Mat
SLA: Sealed Lead Acid.
