Go to a batteries plus if you have one in your area. Do not buy Wal-mart batteries they are horrible. I had to exchange 3 in 3 months. I bought a sealed agm battery from batteries plus, no maintenance, no acid or water to fill, and best of all a 2 year full replacement warranty. Battery cost about $125.00.
What kind was it ? Brand ?? acid?? Im on my 3rd season with my walmart battery... and its slowly going bad.. I solar power maintain it and charge it once every week,,, sometimes skip a week on the charge but i had no problems last two seasons... but so far I went out 4 times and now its loosen its charge faster...
