If you’re in the market for a battery charger for your car, you’re going to soon find out that there’s a big selection out there that you can choose from. From main brands, to brands that you’ve never heard of, it can be hard to choose a charger, but let me give you some pointers on how you can get the best brand, as well as the best deal.
Reviews are your friend – Whenever I purchase something online, I always look for a review online, before I set out, and purchase it. Since the Internet is so big right now, lots of people tend to leave reviews. Look out for positives, and negatives. Yes, the internet is generally filled with a lot of negativity because they can hide behind the keyboard, but don’t let that scare you.
Search in store, then buy – If you don’t know what you want, I always pull this trick off. I will go into an auto parts store, ask questions, and look at them in person. From there, I’ll write down the model, come home, and buy it online. 99% of the time, you’ll be able to save at least 5-10% minimum on your purchases. The online retailers are able to offer a smaller price because they don’t have to pay for stores, fixtures, etc. It’s a win-win for all.
The most important characteristic of a car battery is its ability to hold charge as there is nothing worse than going to start your car and finding that the battery is flat. With car batteries the general rule is that prevention is better than cure as you never know where you might be when your battery goes flat. The key to preventing battery flatness is two things, firstly being aware of the batteries charge by reading the gauge and secondly by using a car battery charger to top up the charge on a battery if you know you won’t be using the car for a while.
Most car batteries have a gauge on them which shows you how much charge the battery is holding at a given time, this gauge should always be full and if it isn’t it could either mean that your battery is lacking water or that there are lead sulfate crystals on the lead plates inside your battery which have bonded tightly. If water levels in a car battery drop it means that the concentration of sulfuric acid will rise making it harder for crystals to dissolve back into the liquid and therefore harder for the battery to hold charge. If the water levels are correct then the only way of returning charge to normal levels will be by taking they battery out of the car and giving it a slow (preferably overnight) charge with a trickle charger. If topping up water levels and deep charging the battery does not led to a return in charge levels then it unfortunately means that the lead plates within have been damaged beyond repair.
As mentioned earlier if you know that you aren’t going to be using your car for a period of more than a month it’s a good idea to get out your car battery charger and top up the charge on your battery. The reason why this is important is that anything other than full charge means that there are lead sulfate crystals on the lead plates inside your battery, leaving these here for a long period of time will strengthen the bond and eventually it will become unbreakable meaning your car battery will never be able to hold full charge again.
