There are several options to buy replacement batteries for a Coleman rechargeable lantern, model 5348-700. I just picked up two new batteries from www.1000bulbs.com for $4.87 each plus shipping. ($20.99 for 2 with shipping!) Do a Google search for: ub645f1 6 volt - 4.5 ah - f1 terminal battery for other options

TO INSTALL OR REPLACE BATTERIES

1. Rotate body of headlamp until lights are pointing down and battery cover tab is to the front.
2. Insert edge of buckle on headband or a coin under tab and twist to unlock and remove battery cover.
3. Install 3 "AAA" cell batteries in the correct orientation as shown on the battery housing. Make certain all 3 batteries are installed
correctly.
4. Replace battery cover by first inserting the tabs on the back of the battery cover under the back edge of the battery housing, and
then rotate down until battery cover snaps into locked position.

You don't remove the screws!!! Use the plastic 'key' that is in the headstrap to remove the cover (opposite side of the headlamp from the switch). Then shake the headlamp to allow the battery cartridge to slide out.

Make SURE you have the batteries in the right way. If you have a battery turned around it won't work, plus you will likely bend the spring inside and then be unable to get the battery in the right way.

If it is the same as the Coleman headlamp I just bought, it claims to have a "easy slide out battery cartridge" On the strap there is a plastic key to unscrew the lid where the batteries are but this doesn't allow you to access them. When you bang the entire thing in your hand to make the cartridge slide out it may not come at first because it is stuck. I partially unscrewed one of the tiny screws on the top of the battery cartridge and pulled on it. This caused it to slide out of the headlamp and I could load it with batteries. I then rescrewed it in gently as its kind of fragile. After this I could get the cartridge in and out by simply tapping the light in my hand with the lid off. The light works great now. Since the screwdriver is so tiny that you need to do this, see if you have a eye-glass repair kit lying around. It may have the size you need.

In the headstrap is a plastic 'key' that you use to remove the battery cover (opposite side of the headlamp from the switch). Once you remove the cover, you can shake the headlamp to let the battery cartridge slide out of the headlamp.
Pay close attention to which way the batteries go in--if you put a battery in the wrong way you can easily bend the springs inside!
