If you can get hold of a good quality car battery charger and you use it correctly, then why not? Charging your car battery at home should definitely be done with caution. If you want to charge your battery at home, we would recommend a slower charge (around 2-3 amps), to reduce the risk of overcharging. You must also check the battery charger's compatability with your car; it's not one size fits all.
You should also be wary of charging your car battery overnight. Sometimes, this could be too long, even if you are using a slower charge. This will cause damage.
If you don't take precautions while charging your car battery at home, then you run the risk of needing to replace it anyway, so please do your research fully before you charge your car at home.
We don't sell battery chargers, but a quick google search will show you plenty of other places that do.
