Few things in life are guaranteed - death, taxes, and beeping smoke and carbon monoxide detectors because the batteries are about to die. We can't do much about the caskets or the IRS, but Camelion's rechargable 9-volt batteries can help with the beeping problem.
These batteries are built to exacting specifications, reliable enough to trust in smoke and carbon monoxide detectors and are rechargable up to 1000 times. The best part about these rechargeable Camelion batteries is not that they put national brand battery prices to shame, it's that they provide guaranteed big name performance at bargain basement prices.
