Frequently asked questions about our services and car batteries

We do not charge any call-out fees for battery fitment and delivery.
Depending on the usage and few other factors* a battery should last between 3* months to 4* years
There are many different types but mainly the followings are the types of battery: calcium battery, AGM battery, EFB Battery, DEEP CYCLE battery, lithium battery etc.

AGM batteries are built using a glass mat separator which enables all the electrolytes required by the battery to be stored within the glass mat, also allowing any gasses given off during charging to be recombined into water meaning that the batteries are totally maintenance-free. The design benefits of the glass mat over conventional flooded batteries enable the battery pack to operate under higher pressure without the fear of insufficient electrolyte between the plates, leading to the step change in durability offered by AGM batteries over flooded. The quality of the glass mat is a critical item in ensuring the optimum life of the battery versus its application. This experience has been gained by Metro from over 20 years of experience in the field using this technology. The automotive application battery designs are balanced with greater high-rate starting performance and cycle life for the increased service/technological requirements of modern vehicle designs.
Both are recombinant batteries (i.e. under normal operating conditions they recombine the gases given off during charging to form water) and both are classified as sealed valve regulated.

The major difference is that in the AGM, the electrolyte is fully soaked into a special absorbed glass mat separator which immobilizes the acid, whereas in the GEL batteries, the acid is mixed with Silica to form a GEL also immobilizing the acid. The benefits of AGM over GEL are that with the use of an absorbed glass mat, the battery pack can be operated under greater operating pressure so improving cyclic durability. With GEL, similar pack pressure cannot be used so durability is usually provided by increased paste density which is good for life but not as good for high-rate start-ability performance as required for automotive applications.

The charge voltage is critical with these types of batteries as both are recombinant batteries. This means that the oxygen that is normally produced on the positive plate in all lead acid batteries recombines with hydrogen given off by the negative plate. The recombination of hydrogen and oxygen produces water, which recycles back to the battery acid, therefore the battery is maintenance-free and does not need topping up.

The sealing vent used in the design ensures that positive internal pressure is maintained to ensure the recombination of the gasses occurs and does not allow the cell to dry out and fail. A game-changing technology indeed.

In addition, the valve must safely release any excess pressure that may be produced during overcharging (such as an alternator rectifier fault), otherwise, the cell would be irreversibly damaged. The excessive pressure that the valve is releasing is both hydrogen and oxygen which cannot recombined within the battery so breaks the cycle, net result is that battery would eventually dry out.

It must be noted that an AGM battery must never be opened once it leaves the factory, as sulphation could occur on the plates leading to an irreversible loss in performance.

Gel batteries are more critical to correct charging as overcharge can lead to the gel being irreversibly damaged, AGM are not subject to this failure mode and hence are more suitable for automotive use.

As with flooded batteries, providing the batteries are kept in a charged state and monitored continuously so it does not drop below acceptable charging level, batteries can be stored without any fears of freezing.
Many people have the impression that when batteries sit on concrete the energy “leaks out”, the truth is that you can let any modern battery sit on concrete without fear of harm or accelerated self-discharge however as stated before it must have to be continuously monitored so the charge rate is not dropped below an acceptable level.

Modern batteries are in hard plastic cases, concrete is generally an excellent surface on which to store a battery.
