Hey there!
Dealing with a completely dead 12V lithium battery can be a bit tricky. Usually, slapping on a charger and letting it do its thing works, but there are a few things to keep in mind to make sure you're doing it right and safely.
First off, it's essential to use the right charger. Lithium batteries need a charger that's specifically designed for them. Using the wrong type of charger can be risky and might even damage the battery further.
When you say the battery is "stone dead," it's important to determine just how dead it is. If a lithium battery is deeply discharged (like, really, really flat), some chargers might not recognize it and won’t start charging. In this case, you might need a specialized charger or a recovery mode feature to revive it.
Also, before you charge, give the battery a quick check. Look for any signs of damage like swelling, leaks, or weird smells. If you see anything off, it's better to play it safe and get a professional to check it out. Charging a damaged lithium battery can be dangerous.
Remember, lithium batteries are a bit different from your regular lead-acid types. They're awesome because they're lightweight and efficient, but they need a bit more care. They don't like being fully discharged and can get damaged if it happens often.
So, in summary, using your charger is generally okay as long as it's meant for lithium batteries and the battery isn’t damaged or overly discharged. If you’re ever in doubt, though, it’s a good idea to consult a professional or refer to the battery's manual. Better safe than sorry when it comes to battery care!
