Power for the engine - What you need to know about car batteries.
All about car batteries can be found here.
We are approaching the season when countless drivers curse their batteries. Especially in cold temperatures car batteries give up - sometimes due to old age, sometimes due to lack of maintenance. What you need to know about buying and maintaining a car battery, you will find right here on the Sawmoco Ltd website!
There are a few things to keep in mind:
First of all, check the owner's manual of your vehicle. Here you will find any specifications of the manufacturer regarding a new starter battery. Be sure to follow these guidelines! Look for important features of the old battery and see what the voltage (in Volts, V), cold-start (in ampere, A), and rated (ampere-hour, Ah) ratings are. If you were satisfied with your previous battery, follow this information.
It is also important that the new battery fits the connections and dimensions of the bracket in your car. New battery models often have a European Type Number (ETN): This number describes rated voltage, cold-start current, capacitance, design and position of the poles.
Filled or dry?
Commercially available both filled and fully charged and dry pre-charged batteries are offered. The latter type reaches its full power only after loading and unloading a few times.
Normally, you buy the filled battery; Only if you need a rather rare type of battery and may need to store it for a long time, the dry variant is the ideal solution.
Sounds complicated or don't want to touch the battery?
No problem. We at Sawmoco Ltd in Sawston do not only sell car batteries for every vehicle, but we will also check the battery for you - either as part of your regular vehicle service, or whenever you want us to have a look.
Just come to see us for a battery check - no appointment needed.
You must pay attention to this when buying a new battery:
They are undercooled and overheated, shaken and stirred: car batteries are subject to wear, and eventually they give up.
The average life expectancy is five to six years - after that, re-charging with a charger will only help for a short time and a new battery must be purchased.
Which battery type?
Calcium (Ca + / Ca): This type of battery is now used in most new cars. They are characterised by low water consumption and low self-discharge rate. Calcium batteries are particularly suitable for installation in the engine compartment, where high temperatures prevail, or in hard to reach places. A disadvantage - especially for cars with start-stop function - is the low cycle stability. This means the battery withstands less loading and unloading.
Low Antimony (Antimony + / Antimony): These batteries have high cycle stability but consume significantly more water. They are hardly used as a starter battery.
Hybrid (Antimony + / Ca-): Hybrid antimony and calcium batteries consume more water compared to pure calcium batteries, so now and again you need to add distilled water. For the hybrid battery is more cycle-stronger than the calcium variant.
You should know that even though most batteries today come with the rating "low maintenance" or "maintenance-free", an occasional look under the hood and on the battery does not hurt.
Make sure that the battery is always clean and dry. Otherwise, leakage currents may form which additionally discharge the battery. The cable connections at the battery poles should be regularly checked for tightness. If the connections are dirty, clean them and apply sparingly with special fat. The battery must be firmly seated in its holder, otherwise tighten the screws. If the battery is mechanically damaged or leaking, it must be replaced immediately!
For starter batteries with sealing plugs: check the liquid level regularly, if necessary top up with distilled water to the maximum mark. In the warm season, a certain water consumption is normal. However, if the battery is noticeably "thirsty", the charging voltage supplied by the regulator may be too high. In this case, come tou our specialist workshop.
Batteries without plugs belong to the so-called maintenance-free types, you do not need to check the liquid level with these batteries.
