When you are into RC cars you will naturally experience a few of the same issues as every other RC enthusiast. One of the first issues that you will most likely encounter as a RC enthusiast is the death of a battery charger. Battery chargers are like any other electronic item, they have a finite life span. While you can expect several years from a battery charger eventually they will fail and need to be replaced.
When you first buy a battery chargers or a new RC car that comes with a battery charger you will want to read your warranty information. You will want to highlight the section that talks about the replacement of battery chargers. Make sure you know how long the warranty will cover a replacement. As you approach the final days of coverage you will want to evaluate the health of your battery charger. If it is not fully charging your batteries or if it is displaying any other type of problems then get it replaced before your warranty expires.
There are several signs that you can look for that will indicate that your battery charger needs to be replaced. First of all if the charger is not fully charging your batteries, then it most likely needs to be replaced. Secondly if it is overheating, then it needs to be replaced. Finally, if it is smoking or giving off a weird smell then it needs to be replaced.
When replacing your battery charger think about upgrading the battery for your RC units. Longer lasting batteries will reduce how many times you have to charge your battery and it will also give you more play time.

I would say that initially it is more likely to be the battery expiring before the charger so be sure to check this first before you go to unnecessary expense
I remember the first time my battery charger died. It was the day before one of my races, and I was scrambling to figure out a way to charge my battery. Luckily a friend came through for me in the ninth inning. I guess I had it coming, though… I’d been using the same charger for 8 years.
I never thought about changing the battery. The only thing I do is simply replace the battery charger. Mine always die quick!

I lost the chance to replace my battery charger and had to pay to get a new one. Wish I had read the tips you have for knowing when to replace battery charger. Thanks, will follow it next time.
[...] When is it time to get a new battery charger? [...]
The problem that we had was that our batteries didn’t get fully charged each time and my son, naturally, become frustrated because the length of play became a little too short. So, we went out and bought a new charger, only to discover that the warranty for the old one had just expired. If we had taken the initiative to find out earlier, then, we might just be able to get a replacement rather than spending money on a new unit. Sigh!
So the battery charger itself is the problem not the battery? Do they offer rechargeable battery pack options like they do with normal batteries? If not I would look at investing in a more expensive battery. The initial investment will be higher but will hopefully save you from frequent replacing your battery and or charger.
Usually old batteries mean they will start getting charged ‘quickly’. I prefer replacing charger after I see a reduction in range (for fully charged batteries). But replacement of ‘charger’ is a different thing altogether.
Overheating is surely one sign.
Thanks for sharing such a useful tip about changing the battery charger. Although most rc enthusiasts have a battery charger, most of them don’t know when to change it unless it couldn’t charge any battery anymore. My battery charger used to face situations mentioned in the article such as unable to fully charge my battery. I thought it was the problem of my battery and didn’t bother about the charger. Thanks for the useful tips.
Thanks for providing such tips which are of great help in our day to day life. Even though we all use it on daily basis or regularly but we do not know exactly when to change it. I was not aware that if the battery charger is overheating then the battery charger has got the problem not the battery. I am surely going to follow your tips in future.
It is true that most of us dont know exactly what do to when we get stuck into such situation.So we must check the warranty of the charger inorder to prevent the cost of buying a new battery. The post has useful tips which we generally ignore while buying a battery.
