My question is: the charger i got has an output of 12volts 6Amps will that charge my dry-cell battery with 200ahs capacity? If yes, how long will it take to full and if no, what charger capacity do i get to serve that purpose? I have had experience in the past where a charger damaged my battery and i dont want to risk that this time. Assuming you are using a standard 12v 7.2 Ah lead-acid battery, it will take approximately 8 hours to charge from empty using a 10 Amp charger. If the battery is only partially discharged, the charge time will be correspondingly shorter. How Long Can a 12V 7Ah Battery Last? As I have reiterated in many articles, the main criteria to charge a battery safely is to keep the maximum input voltage slightly below the full charge spec of the battery, and keep the current at a level that does not cause warming of the battery.

At home i use the electronic RC charger - it can charge anything resembling a battery , but they are expensive and i need to find a simple cheap method (for the bush). So if there are any electronic fundis, please help all of us. You may quite easily modify this constant current charger circuit to make it compatible with the charging of a 6 Volt battery by doing the simple changes in the value of a few resistors. Please refer the parts list to get the required info. Parts list Anyway, a current control facility would be added in the circuit that I would be providing you, so there's nothing to worry In short, Cycle use is when the battery is used to power devices every day, which discharges the battery, and Standby/Float use is when for the majority of the time the battery remains 100% charged in standby. Needless to say, this rude idea can also be implemented using an 18V/2A laptop charger (AC/DC Adaptor) as shown in the below schematic. Here, the second stage is a 15V fixed voltage regulator IC – L7815 – bolted to a bit heavy TO-220 heatsink. Not very tidy, but it works!Wiring and connectors: Use appropriate wiring and connectors to connect the solar panel, battery, and charge controller securely. The heavy duty lead calcium alloy grids provide an extra margin of performance and life in both cyclic and float applications and give unparalleled recovery from deep discharge

charger for lead acid battery proper way 12V 7AH How to make a charger for lead acid battery proper way 12V 7AH

The IC LM338 is an outstanding device which can be used for unlimited number of potential electronic circuit applications. Here we use it to make an automatic 12V battery charger circuit. Why LM338 IC So, the charging current of a 12V/7Ah SLA battery should be no more than 1.75A to prevent thermal runaway and battery expiration. Importantly, if you have other device connected to the battery during charging, it also needs to be powered, so you need to add that to your calculations. In this example, if your battery is wired to a load of 1A, the charging current needs to be 2.75A ( https://www.upsbatterycenter.com/). Keep the questions coming Crude 12V/7Ah SLA Battery Charger – Ideas for Design!The most common way to connect two solar panels is by using a charge controller. This device takes the voltage from both of your panels and outputs it in one direction, so you can now use this power to charge your battery. How long will a 100-watt solar panel take to charge a 12V battery? I have a C-Tek Multi XS7000 charger but according to the specs it can charge 14 - 225Ah batteries. What will happen if I hook it up to the 7Ah?
