12 VOLT DEEP CYCLE BATTERY SOLAR CHARGER SERIES

This will lead to sulfation and reduce your battery’s capacity, so always recharge to 100%.

Never leave batteries partially charged.

Never go lower than 50% depth of discharge - not only will this permanently damage your battery and shorten the lifespan, but it will void your warranty.

To get the best life out of your batteries avoid running more than 3 batteries/strings in parallel.

This ensures that the current is shared equally between the batteries, so that the they are all put under equal stress, and will all have the same lifespan. at 48V, don’t run devices off just one battery to get 12V.

If the batteries are being charged in series e.g.Batteries should not be more than 6 months different in age. For optimum performance, you should be using matched cells. Avoid mixing batteries of different size and age – you will always be limited to the weakest battery in the string.What should I avoid when charging batteries? Sealed lead acid and lithium batteries do not require additional water to maintain them. We also supply lithium batteries which have an expected 10-15 year lifespan.ĭo I need to add water as part of my solar battery maintenance? Our standard Gel VRLA batteries are designed to last about 5 years with proper care. This means that the battery can put out 200A in total over 10 hours, or 2400Wh. For example, our 12V 200Ah battery is specified at C10, or 10 hours. Lead acid batteries are rated based on their capacity, which is measured by how much power a battery can put out in a given amount of time. A deep cycle battery is designed to survive these prolonged, repeated, and deep discharges. This is because there are long periods of time where power is being drawn from the batteries, and when there is nothing to charge the battery. Standby use charge voltage at 25 ☌: 13.5V-13.8VĬycle use charge voltage at 25 ☌: 14.1V-14.4VĪ deep cycle battery should always be used in an off-grid solar application. This is not how your batteries will be used in an off-grid solar application. This is common in uninterruptable power supplies. The only time it gets discharged is when there is there is no other power. Standby use – This is when for the majority of the time the battery remains 100% charged in standby. This is the standard usage in an off-grid solar application. The battery has a cycle of being charged and then discharged every day.

The battery then must be recharged daily. What’s the difference between "cycle use" and "standby use"?Ĭycle use - This is when the battery is used to power devices every day, which discharges the battery. (Also known as Gel Lead Acid or VRLA batteries.)

With the help of our battery manufacturer, Oliter, we’ve put together some answers to common questions to help you understand how a deep cycle battery works, what to avoid, and what you can do to protect your batteries. We get a lot of customers asking us for guidance on solar battery maintenance and how best to use their deep cycle solar batteries to get the most life out of them.
