Devices to recharge car battery?
What are my options? I sometimes left lights on by mistake and drain battery in garage, I was told I have several options besides using a jumpstart cable drawing from others. What are the options; I know of a shop-fitted umbilical thing and portable UPS-like thing, what exactly are they called and how much would they cost? Are there other options I could go for?

You have two options,charge the battery yourself, or jump start the car and let the car's charging system charge the battery. Those devices you are referring to are all basically batteries, that hold a charge until they are needed. They don't charge the system, they just jump start it. Every time a car battery is discharged to the point that it will not start the car, the battery is weakened, and only comes back part of the way. Eventually, you will need a new battery. My first suggestion is to stop leaving the lights on. You can get a beeping alarm wired in to the electrical system to help you if your memory needs the help. Otherwise you are pouring money down the drain. It takes about 15 miles of driving to recharge the battery after each start. Try to keep the short trips to a minimum, and maybe get a charger to keep the battery to full charge. Replacing lead-acid car batteries is expensive, and bad for the environment.

If you intend on making this a habbit and have no interest in preventing it, then you need to get a battery charger. See, even though you may jump start the vehicle, the vehicles AC generator is NOT a battery charger, it will maintain a charge and slightly recharge, but if you run your battery dead you NEED to put it on a charger. BTW, if you have a band new battery, and you run it completely dead 1 time, you just cut its life in half. If you get a brand new battery and do not put it on a charger for a bit before you install it, you just cut 25% - 40% of its life out. Good Luck

you will come across a answer. i'm lazy, so I only plug my huge-unfold battery charger into my DC/AC inverter and use it that way. clarification: I actually have a DC/AC converter for the motor vehicle. So then I take my huge-unfold AA/AAA charger from the living house and only plug it into that.
