Hitachi EBM1830-2 (2) 18V 3.0 Ah HXP Lithium-Ion Batteries
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.  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 is important to fully charge your battery before attempting to use it in your power tools.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.
