Hitachi 326241 EBM1830 18-Volt Lithium-Ion 3.0 Ah HXP Battery
The Hitachi EBM1830 18-Volt Lithium-Ion 3.0 Ah HXP Battery features the  revolutionary Hitachi HXP Lithium-Ion technology. This advanced technology delivers a  battery that is 50-percent lighter than an average NiCd battery, with a longer overall  battery life and a longer run time than any other technology on the market. The HXP battery  features a specialized internal circuitry system that is equipped with a current  interruption and detection system, thermal protector, and an electronic switch to protect  the battery against overcharge and discharge. Hitachi built this battery to be backwards  compatible (it works with the DMR and DVF3 series of 18-volt cordless tools), and since the  HXP battery is built on the 18-volt platform -- the core of the cordless market -- it  prevents users from buying a whole new voltage platform.Hitachi's 18-volt battery weights over 50% lighter than  an average NiCd battery.View larger.Universal charger charges 7.2 volt to 18 volt Hitachi  Lithium-Ion batteries as well as NiCd and NiMH batteries of same  voltage.Circuit technology featured in the battery and universal  charger prevents the battery from losing full power when in use, and overheating when  charging.HXP batteries have a low power discharge while in  storage.The EBM1830 provides a steady level of power  during the entire usage, ensuring the battery's full potential every time. This battery has  a recharge life of approximately 1300 to 1500 times, as opposed to an average of 500 times  for NiCd or NiMH batteries. It has a low power discharge while in storage so you can rest  assured that your tools will always be ready when you are. Not only does the HXP battery  deliver a longer life and extended power, it is also surprising lightweight. When you're  using a tool powered by HXP technology, it feels like you're holding a 12-volt tool while  experiencing the power of 18 volts. This reduces user fatigue and improves manageability  without sacrificing power.This battery is recharged with theHitachi UC18YRL Universal Battery Chargerand is designed to  power a variety of tools, such as theHitachi WR18DL Cordless Impact Wrench, theHitachi WH18DL Cordless Impact Driver,  and other compatible Hitachi tools. It is important to fully charge your battery before  attempting to use it in your power tools. To charge your EBM1830 battery properly, position  the battery so that the nameplate faces towards the nameplate of the charger and press the  battery into place until comes into full contact with the bottom of plate. Inserting the  battery turns the charger on, and the pilot lamp should light up. If the pilot lamp does not  light up, pull out the power cord from the base and check the battery mounting condition.  Once your battery is fully charged, the pilot lamp will slowly blink red and you're battery  will be ready to use. In general, theUC18YRLshould charge your battery in approximately 45 minutes.  Although the variation is minor, ambient temperature above or below room temperature may  effect recharging time.Recharging New Batteries: What to ExpectThe internal chemical substance of your new batteries is not activated, thus the electric  discharge might be low when using them the first or second time. This is a temporary  phenomenon and is not cause for alarm. The normal time required for recharging will be  restored by recharging the battery 2-3 times.How to Make Your Battery Perform LongerThe best way to maximize the life of your battery, is to follow two easy steps. First of  all, remember to recharge your battery before it becomes completely exhausted. When you feel  that the power of the tool becomes weaker, stop using the tool and recharge the battery. If  you continue to use the tool and exhaust the electric current, the battery may be damaged  and its life will become shorter. Secondly, you should always avoid recharging your  batteries at high temperatures. A rechargeable battery will be hot immediately after use. If  a battery is recharged while it's still hot, its internal chemical substance will  deteriorate, and the battery life will be shortened.About Hitachi Power ToolsHitachi Power Tools carries an extensive line of professional grade tools and accessories  for woodworking, metalworking, concrete drilling and cutting, as well as a complete line of  pneumatic nailers, staplers, compressors and collated fasteners. During the 1980s Hitachi  Power Tools built its reputation for quality on the success of its pneumatic framing nailer  and sliding-compound miter saws. In 1995 Hitachi Power Tools was renamed Hitachi Koki USA to  denote the addition of manufacturing to the United StatesFrom headquarters in Atlanta, GA, and satellite offices in Chatsworth, CA, and Toronto,  Ontario, Hitachi Koki USA supports nearly 2000 retail locations carrying Hitachi tools and  over 1000 authorized service centers. The field sales force and service technicians  constantly provide information to engineers to refine the product selection. Many tools in  the line are designed and offered for use only in North America.
