2 Specifications: Many battery chargers are available on the market, but few of them a re universal chargers that can be used for all battery types. Using our kit, batteries of different voltages and c apacities can be charged both quickly and normally.
3 Assembly hints 1. Assembly (Skipping this can le ad to troubles ! ) Ok, so we have your attentio n. These hints will help you to make this project successful. R ead them carefully. 1.1 Make sure you have the right t ools: • A good quality soldering iron ( 25-40W) with a small tip.
4 Assembly hints 1.3 Soldering Hints : 1- Mount the component ag ainst the PCB surface and caref ully solder the leads 2- Make sure the solder joints are cone-shaped and s hiny 3- Trim excess leads as.

9 Connection 24. CONNECTION Connect a battery to the ACCU + and - connectio n. One of the battery holders from our range can be used such as: • Type BH9V for 1 9V cell. • Type BH322B for 2 AA cells (penlight). • Type BH341B for 4 AA cells. • Type BH363B for 6 AA cells.
10 • Mount a shunt over the 14h position. • Select the battery voltage to be connected using a shunt on the 1.2V to 9.6V connection. • Select the charge current with a shu nt between 15mA and 750mA. The charge current of a battery can be determin ed by dividing the battery capacity by 10 (the n select the closest to the charge current).
11 • Mount a shunt over the 52 min position. • Select the battery voltage to be connected using a shunt on the 1.2V to 9.6V connection. • Select the charge current with a shunt between 15mA and 750mA. The charge current of a battery can be determin ed by dividing the battery capacity by 10 (then select the closest to the charge current).
12 NOTE: Only use the quick charge facility in the event of an emergency, as this type of chargi ng can reduce the battery lifetime. Never mix batteries of different capacities. Never select two voltages or current settings simultaneously.
