Flooded lead acid batteries must not be used inside your house (due to the release of highly explosive hydrogen gas while in use), so instead they should be kept in a vented enclosure or battery box. This enclosure/box can be inside an insulated shed or garage for warmth if there is adequate ventilation for the off-gassing.
Lead-Acid batteries are still widely used due to their features, such as: Each cell can be checked for charge status using a hydrometer, cell tester, or multimeter. The electrolyte level can also be maintained by adding distilled water.
Nickel-metal hydride battery is similar to NiCd battery, but the hydrogen-absorbing anode is an alloy instead of cadmium. This type of battery gets to have two or three times the capacity of a NiCd battery of the same size and a less significant "memory" effect. Alkaline batteries may be non-rechargeable (disposable) or partially rechargeable.
The nickel-cadmium battery employs nickel (Ni) and cadmium (Cd) metals as chemical reagents.

Old coal mines could be the solution for storing renewable energy
By Bryony Cottam. Renewables are cheaper and more available than ever, but the green-energy revolution relies on our ability to store that energy. Wind and solar technologies can''t produce continuous power, so they can''t replace coal and gas plants unless we''re able to store the electricity that they produce for when the wind isn''t blowing or the sun shining.
