Prices shown in currencies other than US Dollars are estimates based on current exchange rates. We will charge your credit card in US Dollars on the day your order is shipped, and the conversion to your local currency will be done at the prevailing rate by your credit card issuer.
C. Crane will not mark your parcel as a “gift”, declare a value lower than the actual price paid, or otherwise prepare false customs information.
You may have noticed this new acronym popping up on some of our products. RoHS stands for Restrictions on Hazardous Substances, and it's a directive that could have a huge impact on the production and disposal of consumer electronics. First adopted in Europe in 2006 (and later adopted in California in 2007), RoHS restricts the use of six dangerous substances in lots of common electronics. According to the official RoHS compliance Web site (www.rohs.eu), the RoHS symbol indicates that "new electrical and electronic equipment put on the market does not contain any of the six banned substances: lead, mercury, cadmium, hexavalent chromium, poly-brominated biphenyls (PBB) or polybrominated diphenyl ethers (PBDE), in quantities exceeding maximum concentration values."
While some military and medical equipment is exempt from RoHS compliance, the electronics governed by the standard are among the most common you'll find in your home, from radios to MP3 players to cell phones and (increasingly) computers. In practical terms, the standard protects factory workers at the production level, sharply reducing their exposure to hazardous substances. The standard also has a profound impact on the disposal and recycling of electronics, in that disposed substances will no longer have at least six of the most hazardous chemicals formerly found in electronics, and recycled electronics will not expose workers to toxics as they harvest components.
Heavy battery users now have a fantastic new choice that has dropped dramatically in price. They have much more power than even alkaline batteries, can be recharged or topped off anytime, and don't have the same "memory effect" as NiCad batteries. Their only drawback is all NiMH self discharge about half their energy in two months without use. This confirms their best purpose is for a heavy battery user. Can be recharged about 500 times and last for years. They work great in high drain situations like a digital camera or a transceiver.
Using NiMH rechargeable batteries instead of single-use alkaline batteries can save you a lot of money. If you own a digital camera, you know that they use alkaline batteries at an alarmingly fast rate. NiMH batteries, on the other hand, were developed especially to meet the higher energy demands of today's electronic devices. NiMH batteries are more powerful and more environmentally friendly than standard alkaline or NiCad batteries. NiMH batteries also don't suffer from the "memory effect" like NiCad batteries.
Rechargeable batteries need to be "conditioned" – charged and discharged at least three or four times – to come up to full capacity.

Generally no, but our own research shows a full charge and discharge cycle for the first three uses significantly increase the capacity of NiMH batteries. However they can be recharged at any state of discharge with no danger to the batteries.
Customers have advised us that when charging high capacity “D” cell batteries for the first time, it is best to only charge two at a time because the current requirements of the batteries may be greater than the battery charger can handle. It is also recommended to charge and drain batteries several times to achieve maximum conditioning (this is true for all rechargeable batteries we have tested). The above does not apply to the new QuickCharger 2.
