7.4 V lithium battery lithium battery _2400 ma 18650 performance parameters of the description: Nominal voltage: 7.4 V (three string of ten and, the customer designated) Nominal capacity: 2400 (mAh) (the customer designated) The battery size: 19 37 * 66 * (mm) (the customer designated) The battery resistance: more than 80 (m ?) The overcharge protection: in the P + and P-between plus charger, for recharging the battery, the battery voltage filling to overcharge test voltage (8.4 + /-0.04 V), The protection circuit action, to cut off the charging pathways, realize the overcharge protection. Discharge protection: in the P + and P-between connected to load let the battery discharge, when the battery voltage drop to put voltage (6.0 + /-0.1), The protection circuit action, shut off the discharge pathways, achieve discharge protection. Short circuit protection: when P + and P-short circuit, protect the circuit will be in 5-50 uS quickly in action, cut off access, achieve short circuit protection. Over current protection: the voltage of the V-up to 0.15 + /-0.02 V), protect the circuit will be in 5-26 ms quickly in action, cut off access, realize the over-current protection. Cycle: 300 times and 80% of the power Applicable temperature:-20 / + 60 (?) Application: 1) communication equipment: cordless phones, mobile telephone, fax machine 2) audio-visual equipment: cameras, portable audio, MD, player, portable DVD and VCD players, wireless speakers 3) electronic equipment: notebook computer/notebook computer, PDA, and portable machine 4) other purposes: electric razors, and electric toothbrush, and portable vacuum cleaner Note: the battery assembly method according to your requirements, such as protection of parameters, a combination of voltage, capacity battery, the battery size, packaging yan
