Remember Me?

Many newer vehicles have moved batteries to the trunk area for a variety of reasons, including better weight distribution in the vehicle, more space under the hood and less potential damage from engine heat. However, these newer vehicles require some additional steps to be taken when replacing batteries. Battery replacement in the BMW i is not an overly-challenging task, but you will need some basic hand tools to unfasten and re-tighten the connections. You will also need to make sure you attach the vent tube to the battery, as in the unlikely event that the battery is severely overcharged and vents fumes, those toxic and flammable fumes should be directed to the outside atmosphere. You may also need to "register" the battery with the vehicle's charging system, which can often be done with a scan tool.

Modern cars consume electrical current all the time, whether the car is being driven or not. Additionally, the variety of battery types can be bewildering. Flooded or wet cell batteries are the most common type of lead-acid battery in use today. An outer plastic shell contains inner cells, each with a a grid of lead plates along with an electrolyte based on sulphuric acid. Gel cell batteries have silica dust added to the electrolyte, forming a thick putty-like gel. This gel material allows electrons to flow between plates but will not leak from the battery if the case is broken. Many gel batteries also use one-way valves in place of open vents, which help the normal internal gasses to recombine back into water in the battery, reducing gassing. AGM batteries feature fiberglass mesh mats between the battery plates which serves to contain the electrolyte. AGM batteries contain only enough liquid to keep the mat wet with electrolyte — If the battery is broken no free liquid is available to leak out. More often than not, AGM batteries are mistakenly identified as gel cell batteries. Both have similar traits: non-spillable, deep cycle, may be mounted in any position, low self discharge, and safe for use in limited ventilation areas. But AGM batteries outsell gel cell by at least a to 1. Also, gel batteries tend to have very narrow charging profiles and can be damaged easily by charging them inappropriately. So, a setting that is suitable for a gel battery may not be suitable for any non-gel battery.

AGM type batteries may not require venting.

A car battery stores energy that is produced by the alternator and helps start your car. The battery's stored energy also helps you use electrical accessories while the vehicle is not running, like the radio, lights, power outlets, and more. Car batteries wear out over time from exposure to high temperatures, corrosion, or a lack of battery maintenance. When automotive batteries begin to fail, they may no longer hold a sufficient charge to start the vehicle. If you notice the engine cranking slowly or taking longer than usual to turn over, it might be time to replace your battery. If you see abnormal amounts of corrosion around the posts or even the battery casing itself, your battery case may be leaking, and the battery should also be replaced. A bad car battery can cause a slow-turning engine, inconsistent or hard starts, or your vehicle's accessories or sound system may not operate when the engine is not running. You can find batteries for your car, truck, or SUV, as well as golf cart batteries, heavy-duty vehicle batteries, lawnmower batteries, and more.
