LABC1 • 4 Quick Batt ery Theor y To begin, w e should cover a few facts about lead acid batteries in general. Most traditio nal histor ians date the invention of batt eries to the e arly 1800’s when experiments by Alessandro Volt a generated electrical current f rom chemical reactions betw een dissimilar me tals.
LABC1 • 5 solution. As more energy is drained from th e battery, the ratio of sulfuric acid to water decreases and the created lead sulfate byproduct begins forming on the electrode plates. A low hydrometer reading means the chemical makeup that generates the free electrons is diminished so not as much energy is stored f or use.
LABC1 • 6 plates on a regular basis or over an extended period of time, the charging process will not be able to restore the batter y to its former f ull potential.
LABC1 • 7 batteries. Granted, that might take a wh ile. The other support components on the board help VR1 to know when to adjust its output voltage up or down to ensure the proper charging rate of the battery.

LABC1 • 11 RAMSEY "Learn-As-You-Build KIT ASSEMBLY There are numerous solder connections on the LABC1 printed circuit board. Therefore, PLEASE take us seriously wh en we say that good soldering is essential to the proper operatio n of your batter y charge r kit! • Use a 25-watt soldering pencil with a clean, sharp tip.
LABC1 • 12 LABC1 BATTERY CHARGER KIT ASSEMBL Y Although we know t hat you are anxious to complete the assembly of your battery charger kit it is best to f ollow t he step-by-step instructions. Try to avoid the urge to jump ahead installing components.
LABC1 • 13 5. Install C1, 1000 µF electrolytic capacito r. This part also must be installed properly to f unction. In fact , this capacitor has the potential to explode if installed in reverse polari ty. T he PC board silkscreen shows the positive hole an d the band on the capacitor sho ws the negativ e side.
LABC1 • 14 Take a moment now to check your previous solder joints for “opens” w here the solder did not completely flow aro und the connection, or solder bridges between close ly spaced pads.
LABC1 • 15 right, you can do it with the rest. These will all be mounted in stan d-up f ashion, just like D17 wa s a fe w steps ago. Again, the body of the part is placed in the hole with the circle around it and the other lead is bent up and around to fit into the other hole.
LABC1 • 16 ASSEMBLY INSTRUCTIONS FOR CUSTOM CASE The enclosure is a key element to th e overall pride you will have upon completing your Ramsey kit. The encl osure will show how yo u were able to “build f rom scrat ch” a comme rcial piece of high-tech elect ronics.
LABC1 • 17 ADJUSTING YOUR LABC1 B ATTERY CHARGER Now th at you have finished the assembly stage there is only one more step before you start ch arging your batteries. The necessary alignment is to adjust R2 for the proper ‘Float’ voltage w ith reference to t he current air temperature around diodes D5 to D14.
LABC1 • 18 SAFETY CONSIDERATIONS All lead-acid batteries produce Hydroge n and Oxygen gas durin g the electro- chem ical recha rging pr ocess. The pr o duction of these gases is increased if overcharging occurs, commonly caused by too high of a charge voltage.
LABC1 • 19 that R4 is use d in the SO C fe edback loop th at varies th e charging te rminal voltage in accordance with the battery’s present state. Lowering the value of R4 to 15K or less w ill have the eff ect of increasing the mode differential voltage.
LABC1 • 20 TROUBLESHOO TING GUIDE If your LABC1 does not work correctly after construction, recheck the following: • correct orientation of VR1 , and U1 (see PC board layout diagram) • correct p.
LABC1 • 21 CONCLUSIO N W e sincerely hope that you enjoy the use of this Rams ey produ ct. As always, we have tried to compose our manual in the easiest, most user-friendly format that is po ssible. As our c ustomers, w e value your opinions, comments, and additions that you would like to see in future publications.
