Which is the best battery to be used with solar panels for small scale applicati

[Shawnturner]

Hi,

I already have a small scale solar setup with 20watts panel and 2*7AH lead acid batteries.

I bought the batteries 1 year ago and already it has started to loose lot of its charge by just connecting a small led bulb of 5watts.

So please suggest me a good battery which is best compatible for solar power.

And how much does it cost?

Please help.
Thanks!

I didn’t find the right solution from the Internet.
