Batteries are known to be amongst the volatile parts of a car’s mechanics.
One moment they are in perfect working condition and the next you cannot get the car to catch on. This can often be attributed to an electrical problem causing the car to not start up thereby leaving the drivers stranded in a location far away from the nearest auto repair shop. The best thing to do to make a situation like an electrical crash less possible would be to get a good battery.
Investing a good amount of money on a battery is an investment that speaks for itself in the long run. A good lead acid liquid battery goes between the price ranges of $70-$130. Liquid lead acid batteries have been quite common since their development in 1859 and according to the experts they are the least expensive batteries in the world of automotive engine starters. In order to make this battery more manageable and eco-friendly, the sealed liquid lead acid battery was developed. Another possible investment can be the Value Regulated Lead Acid battery (VRLA) which includes gel and absorbed glass mate that are not in any way liquid.
There is also the Absorbed Glass Mat (AGM) battery
Which is made up of silicate glass fibres then mixed with boron forming a mat that holds the electrolyte. This battery was put into production in the year 1972 but its use was targeted towards military and non-vehicle applications like boats, motorcycles and electronics. As of now, the AGM batteries are now being used in car production. AGM (absorbed glass mat) batteries can cost from $155 to $260 but have more advantages over liquid lead acid batteries.
The AGM has a lower non-use discharge rate than the liquid lead acid batteries. Because of the high rate of power consumption used by today’s vehicles, automotive manufacturers have turned to AGM batteries as their new car power source. The 2007 models of the BMW were the first to have the AGM batteries due to their computer functions and braking. AGM batteries are in more ways than one better than the liquid lead acid batteries but the downside of the AGM is that care has to be taken not to overcharge the. Their charging rate happens to be faster with a standard output of 14.5 volts.
A solar panel with a trickle charge is recommended when an AGM battery is put into a non-use vehicle.
If charged over the standard 14.5 volts, the AGM battery will go bad. The vehicles that encounter the most problems with AGM are the sport vehicles as a result of the rough environment in which they are put into use. It is best to get rid of the old plug in garage battery charger and get a new one that sustains volts instead of amps. An AGM battery charger will sense a very low voltage in the battery and will start the recharge whereas an old charger does not sense low voltage and will not charge the battery.
The AGM batteries are known for starting up easily even after years of storage without any problem. The batteries can also attain full charge with no problem after years of piling up dust in garages. The AGM batteries can be put into vehicles and the negative cable disconnected in the one that is not being used often anymore and it starts right up when the engine is run occasionally. There have been negative reviews and complaints only about the AGM failing often but according to findings, this can be only attributed to situations where best practices are not involved. The batteries can be left for a long period of time without use but it is highly recommended that it be stored with a solar panel that has an extremely low trickle charge to prevent any chance of it being overcharged. It is imperative that the negative cable be disconnected when the battery is not in use.
When it comes to the AGM against the Gel cell
The AGM tends not to warp easily due to its thicker plates therefore; during deep discharges they resist the build-up of sulphur that improves the chances of destroying a battery. The batteries comprising of wet cells tend to spoil after 3 to 4years maximum. On the other hand, the life of the AGM battery goes to about 8- 10 years that is if proper care is taken.
As a result, the clear recommendation is the Absorbed Glass Mat (AGM) if proper care is taken.
