12 Volt Deep Cycle Batteries For Solar
Buy deep cycle 12V batteries for small scale solar powered projects
storage | shoppingMost of our articles about
lead acid batteries refer to large (20Ah+) batteries connected into a
battery bank. Such battery banks are typically used for large scale
solar charging - for example, to power the lighting in a home.
We have also looked in detail at the
solar charging of
NiMH AA cells for very small scale solar projects - for example, to recharge an iPod, torch, or radio.
There is a middleground of projects for which a
12V battery is required to be charged by a solar panel, but for which the battery need only be relatively small - i.e.
1Ah to 20Ah in size. Unlike AA cells and large sized batteries, these can be quite hard to find and can also be overpriced. Therefore in this article we will look at what is available.
12V Batteries for Solar Applications
For reliability and easy maintenance, a sealed
deep cycle
lead acid battery should be selected. Non deep cycle batteries are completely unsuitable for solar applications since they are not made to be
discharged deeply - something which will happen from time to time during periods of cloudy weather. Choosing a
sealed battery reduces
battery maintenance to zero, since nothing is ever going to leak out, and there is never any need for
watering.
The most reliable, best quality, and fairly priced small 12V lead acid batteries we have found are from
Haze - available for sale online in the UK at

Mains Powered Charger for 12V Lead Acid Batteries
A plug in
mains charger for a 12 Volt battery is a very useful item to have. When you purchase a battery, it needs to be fully charged before it is first used. Also, there may be times when
solar power alone is insufficient to get the battery up to full charge.
Pictured above is an excellent basic
automatic 12V Lead Acid Charger from
Rapid. This charger is fitted with insulated
crocodile leads for easy connection to small 12V batteries, and has in-line
fuse protection. It provides an output current of
720mA (8.6 Watts output) - sufficient to safely charge most small batteries over night. When the battery reaches full charge, the charger turns off automatically and a red
charge complete LED lights up. This product is available for around £10 and is an excellent partner for the
12V batteries listed above.
