There are a lot of white lights, lasers andÂ illuminatedÂ optics on the market that use the small, powerful 123A batteries. Â These batteries work great, but they tend to be expensive.
Surefire is now offering a rechargeable 123A battery kit. Â The kit includes two rechargeable batteries, the charging unit and power adapters for both home (110v AC) and the car (12v DC). Â MSRP on the kit is $29 and additional batteries can be bought for $12/pair.
Rechargeable 123A batteries can be used hundreds of times, offering aÂ significantÂ cost savings over their lifetime. Â However, the rechargeable batteries do not hold as powerful a charge, meaning that runtime is only about 50% of the normal runtime on typical non-rechargeable 123A batteries.
