Most batteries have a voltage of 12V. Here is how many amp hours battery you need to power a 100W device for 8 hours: Ah = 800W / 12V = 66.67 Ah. This means you will need a battery with at least 66.67 amp-hours (Ah). Here is the step-by-step procedure how to calculate Ah of a battery: Calculate the electricity needed to power an electronic device.

Learn more WhatsAppStandard lead-acid cells have a low self-discharge, about 5% per month, so continuously monitoring makes little sense. To measure this I would take a reading with a DMM every few days, and you may need to take readings over a period of …
Learn more WhatsAppIf the battery is not new, it should be charged with a battery charger and then left to sit for several hours to eliminate surface charge. With your multi-meter, measure the voltage across the battery''s two terminals. A fully-charged 12-volt lead-acid battery should have a voltage of at least 12.6 volts across the terminals.

Learn more WhatsAppIt isn''t good to run a battery all the way down to zero during each charge cycle. For example, if you want to use a lead acid battery for many cycles you shouldn''t run it past 80% of its charge, leaving 20% left in the battery. This not only extends the number of cycles you get, but lets the battery degrade by 20% before you start getting ...
