The L6 was launched last September alongside the CoolPix L5 that I reviewed last week. It is a basic six-megapixel, 3x zoom model 
with a 2.5in monitor screen. It is currently available for around £123, which might sound quite cheap for a good quality compact, but is actually slightly above the market average. In terms of specification it compares with the likes of the Olympus FE-210 (£95), Kodak EasyShare C653 (£100), Pentax Optio E20 (£100), Sony Cyber-shot DSC-S500 (£100), Ricoh Caplio RR630 (£110) and Fuji FinePix F20 (£135). So far, so average, but the CoolPix L6 has one extraordinary ability. Nikon claims that it has the longest battery life of any digital camera on the market, capable of over 1,000 shots on a pair of AA cells.
This is quite an audacious boast, and it is indeed most likely true, but whether Nikon can claim all the credit for it is debateable. The L6 is supplied with two Energizer E2 Lithium batteries, high powered lightweight non-rechargeable AA cells specifically designed for small high-tech devices like digital cameras, and which have been available in most good electrical stores for several years. It is these batteries that provide the L6’s seemingly miraculous performance. As it happens I tested the Energizer Lithium batteries when they were first introduced in 2001, comparing their performance to a range of other popular AA batteries, and I found that in a digital camera they lasted well over five times as long as the next best performer. I’ve recommended Energizer E2 Lithium as the best AA digital camera batteries ever since.
