Battery Knowledge: Types of Car Batteries Available

Nov 23, 2021

It's safe to say that almost every Malaysian household owns a car. Even as car-sharing trends continue to define how private and public transport systems work, the majority of Malaysians still find value in possessing a car. If you are among the majority of motor vehicle owners, you do realize how important the car battery is for the optimum operation of your vehicle, right?

When was the last time you grappled with a dead or depleted car battery? The experience can easily drive you over the edge. If you are a greenhorn when it comes to the different types of car batteries, you may end up having many frustrating jump-starting attempts.

And let’s not forget: car batteries are an integral part of a car’s ignition system. They are responsible for supplying electrical energy to the car’s starter for cranking up the engine and powering up various car components like radio, lights, etc.

So, to help you streamline the selection process, here is a list of five common types of car battery that everyone should know about and where to find a great car battery retailer in Selangor.

What are the types of car batteries available out there?

a) Wet Cell Batteries

When buying your car battery, you may consider wet cells or flooded batteries. These types of batteries have a combination of lead, sulfuric acid, and water. The combination creates the battery’s electrolytes.

Compared to the other types of batteries, wet cell batteries are cheaper. However, these batteries have an inherent problem related to their limitations in terms of the convenience they present. Wet cell batteries are the original types of rechargeable batteries used in most cars in the past.

But, over time, these batteries have lost traction considering the high energy demands in most modern cars. You are less likely to find electric and hybrid vehicles using wet cell batteries. With the rise in energy efficiency demands in most modern autos, you may need to consider more convenience.

b) EFB Battery (Enhanced Flooded Battery)

Modern cars have high energy demands that most batteries are unable to meet. The EFB car battery presents a timely solution to this concern.

This type of battery is an improved version of the flooded or wet batteries previously in use. EFB batteries guarantee better performance and durability as compared to traditional cells.

Have you been wondering what type of batter is best for your car? Well, the EFB battery offers you the durability and energy efficiency you crave.

Compared to other types of batteries, the EFG battery is superior, with up to 85000 maximum engine starts. You no longer have to worry about a car battery that can even your car needs. With EFB batteries, jumpstarts are a thing of the past.

c) AGM Battery

AGM (Absorbed Glass Mat) batteries are becoming more popular with modern vehicles as the demand for higher CCA (cold cranking amps) & RC (reserve charge) increases. AGM batteries are just like flooded lead acid batteries, except their electrolyte is absorbed and held in glass mats, as opposed to freely flooding the plates. There is no excess electrolyte in an AGM, so they are able to operate in any orientation (even upside down!), without ever having to worry about spillage.

All AGM batteries are VRLA (Valve Regulated Lead Acid) in design, and tend to run a slightly higher than atmospheric internal pressure. This pressure is controlled by an inbuilt valve regulator. When installed internally (in the boot or inside the cabin), a vent tube must be connected. Vent tubes must not be kinked in any way, and must vent outside the vehicle. Be aware that AGM batteries are heavier than a wet battery for the same case size, so care must be taken when lifting and installing them.

d) Calcium Battery

Conventional low-maintenance batteries use grids of lead-antimony which is readily available, inexpensive, easy to cast, and used to produce rechargeable batteries that offer efficiency and low cost. In a calcium battery the antimony is totally substituted with calcium in all plates. This results in double the shelf life and virtually no gassing in the battery, resulting in less maintenance.

Calcium batteries do require a higher charge voltage (nominally 15 volts) to achieve the same level of charge as a normal antimony battery. They also require a periodic equalisation cycle to help maintain optimum operating condition. When installed in a vehicle designed for an antimony battery (i.e. a traditional 12 volt system which charges at 14 volts) the battery will only achieve 85% state of charge.

e) Deep cycle battery

A deep-cycle battery is a lead-acid battery designed to be regularly deeply discharged, using most of its capacity. In contrast, starter batteries (e.g. most automotive batteries) are designed to deliver short, high current bursts for cranking the engine, and to be frequently discharged of only a very small part of their capacity.

Deep cycle batteries have much thicker plates than a regular automotive battery and are designed to be discharged down as much as 80% time after time. The major difference between a true deep cycle battery and others is that the plates are solid lead plates - not sponge. This gives less surface area and therefore less "instant" power which starting batteries need.

f) Spiral coil battery

A spiral coil battery is an AGM battery, but with a different construction. Like conventional AGMs, it is a high output battery, and is often found in high performance or off road vehicles that require extra torque for starting. Positive and negative plates are rolled together with a thin layer of absorbed glass mat in between providing more surface area and therefore produce higher current carrying capacity. These batteries are more resistant to excessive vibration, heat and higher charge rates. The spiral battery can have a shelf life up to 18 months without affecting starting ability.

g) Gel battery

Gelled batteries, or "gel cells" contain acid that has been "gelled" by the addition of silica gel, turning the acid into a solid mass that looks like hard jelly. The advantage of these batteries is that it is impossible to spill acid even if they are broken. The disadvantage is that they must be charged at a slower charge rate to prevent overheating. Excess heat will turn the “gel” into a liquid, damaging the cells. Gel batteries are often found in golf buggies, back up for house alarms and electric toys. There is a caution - gel cell batteries cannot be fast charged on a conventional automotive charger or they may be permanently damaged.

Checklist To Check Before Long Journey

20 Dec, 2021

Malaysians love road trips; that's a fact! With COVID-19, road-tripping is going to be an even more popular way of travelling for many Malaysians! In fact, the roads are already loaded up with vehicles and people who are trying to escape the everyday grind and find an escape somewhere. However, nothing spoils your travel plans like a car breakdown when you're far from home and away from your usual mechanic or service centres! As road trips are supposed to be for fun and relaxation, but a car breakdown will turn that time for pleasure into absolute misery. But you can avoid that if you take some time beforehand to get your car ready for that long trip! Before you leave for your next road trip, here's a quick car battery checklist before long journeys to other states! We'll also cover where you can get your car battery checked for free and where's the best supplier of car battery replacements! A quick checklist before you go on a long journey: a) Check that all your car's fluids are good to go You can either send your car in to a service centre/workshop or do it yourself! Just park your car on a flat ground area and wait a few minutes after you switch the engine off. Then your readings will be correct! If you know how to do it, check the brake fluid , power steering fluid, engine oil, coolant, transmission fluid, and even windscreen wiper fluid. If any of them are low or look like they're in bad condition, top them up or change them entirely! b) Pay special attention to your engine oil Road trips involve long hours of driving at high speeds - this stresses the engine significantly if it's not performing at its optimal condition! You should perform the standard dipstick test - if it's showing heavy, black signs on the dipstick, or if it's been more than 6 months or you have driven more than 5,000 km since the last engine oil change, consider replacing your engine oil entirely (and even your oil filter) before you depart on the long road trip. For example, CHEMPIOIL Ultra XTT engine oils are fully imported oils that are of high quality for the latest generation of modern gasoline and diesel engines with and without turbocharge! They are a Swiss brand of vehicle lubricants and fluids that can promise: Optimum protection for your car's engine at all temperatures Worry-free driving for the long run Quality 100% synthetic ester technology Reasonable pricing that boasts superior quality over many other engine oils c) Keep a wary eye out for your car's timing belts and hoses Timing belts and cooling system hoses are the most notorious parts for breaking down during road trips. Your car's belts will need to be replaced if they've become loose or worn - this can be detected via screeching sounds or vibrations. If you know how to, you should also inspect your engine's cooling system hoses in the case of cracks, leaks or any other damage to avoid overheating your engine on the road! d) Check the car battery Nothing ruins a road trip vacation like a dead car battery! Hence, it's important to keep your car battery in tip-top shape before going on a long drive! Typically, a lead-acid car battery can last around 4-5 years, but it's always safer to have a quick check even if it's a new-ish car battery. You can have it checked for free at Ex Power Battery ! If your car battery is old, you should definitely get it tested and replaced, as you won't want to wake up the next day with a dead car! A few signs that tell you need a battery replacement include slow or sluggish starts and dim headlights, especially when your car is idle!
