There are many stores and websites that sell good alkaline 12v battery chargers. A few examples are Amazon, Newegg, Home Depot, Lowe's, and Radio Shack.

Few alkaline battery chargers have been made. The process to recharge alkaline batteries hasn't been very successful. Most rechargeable alkaline batteries will only recharge a few times and you have to make sure you use the correct type of charger. It can be very dangerous if you use the wrong one.

For Alkaline batteries i recommend putting in great sunlight or buying an electrical battery charger.

the battery charger and the charger are the same thing. the charger charges the battery and the laptop runs off the power from the battery.

hope this helps

sure, you can buy a battery charger that will charge any car battery.
