Can a motorcycle battery be desulfated? That's a question I get asked a lot as a motorcycle battery supplier. I've seen all kinds of battery issues over the years, and sulfation is one of the most common problems riders face. So, let's dive into this topic and see if we can find some answers.
First off, what is sulfation? Well, when a lead - acid battery (which is what most motorcycle batteries are) discharges, lead sulfate crystals form on the battery plates. That's a normal part of the battery's operation. But if the battery isn't recharged properly or is left in a discharged state for too long, these crystals can build up and harden. This is sulfation, and it can really mess with your battery's performance. The hardened crystals reduce the battery's ability to hold a charge and can even lead to a complete battery failure.
Now, the big question: can we get rid of these pesky sulfate crystals? The short answer is yes, in some cases. There are a few methods out there for desulfating a motorcycle battery.
One common method is using a desulfator device. These are small gadgets that you connect to your battery. They work by sending high - frequency pulses through the battery. The idea is that these pulses break up the sulfate crystals, allowing them to dissolve back into the electrolyte solution. It's kind of like using a jackhammer on a big block of ice; the pulses chip away at the crystals.
I've had customers who swear by these desulfator devices. They say that after using one, their old, sulfated batteries came back to life. For example, a guy who had an old 12V 5Ah Deep Cycle Motorcycle Battery With 85 Amps CCA that was barely holding a charge tried a desulfator. After a few weeks of using it, he noticed a significant improvement in the battery's performance. The bike started up more easily, and the battery lasted longer between charges.
Another method is the Epsom salt method. Epsom salt, which is magnesium sulfate, can be mixed with distilled water to create a solution. You carefully open the battery cells (this should be done with extreme caution, as battery acid is dangerous) and add the solution to each cell. Then, you charge the battery slowly. The magnesium in the Epsom salt is thought to help break down the sulfate crystals.
I have to say, though, the Epsom salt method is a bit more of a hit - or - miss. Some people have had great results, while others haven't seen any improvement at all. And there's a risk of over - diluting the electrolyte or causing other chemical imbalances in the battery if you don't do it right.
But there are limits to desulfation. If the battery is severely sulfated or if it's very old, desulfation might not work. For instance, if a battery has been sitting in a shed for years, completely discharged, chances are the damage is too far gone. The internal structure of the battery plates might be so damaged by the sulfation that even if you break up the crystals, the battery won't function properly.
Also, different types of motorcycle batteries respond differently to desulfation. Gel batteries, like the 12V 9Ah Gel Motorcycle Battery, are a bit more sensitive. Their internal structure is different from traditional flooded lead - acid batteries. Desulfation methods that work well for flooded batteries might not be as effective for gel batteries, or they could even cause damage.
AGM (Absorbent Glass Mat) batteries, such as the YTZ9 - 3 12V 9Ah VRLA AGM Powersport Battery, also have their own quirks. They're sealed, so you can't easily access the cells like you can with a flooded battery. This makes methods like the Epsom salt method pretty much impossible to use. However, desulfator devices can still be used on AGM batteries, but you have to make sure the device is compatible with AGM technology.
As a supplier, I always tell my customers that prevention is better than cure when it comes to sulfation. Here are some tips to keep your motorcycle battery in good shape:
- Keep the battery charged: Make sure you charge your battery regularly, especially if you don't ride your bike often. A battery tender is a great investment. It keeps the battery at a proper charge level without overcharging it.
- Avoid deep discharges: Try not to let your battery get completely drained. If your bike has a lot of electrical accessories, like lights or a stereo, be aware of how much power they're using.
- Store the battery properly: If you're not going to use your bike for a long time, remove the battery and store it in a cool, dry place. And make sure it's fully charged before storage.
In conclusion, while desulfating a motorcycle battery is possible in some situations, it's not a guaranteed fix. It depends on the severity of the sulfation, the age of the battery, and the type of battery. But it's definitely worth a try if you have an old battery that's on its last legs.
