Never buy DCS Garbage batteries
Never buy DCS Garbage batteries. Dropped its capacity by 50% in the first 2 years. The customer service is the worst i've ever dealt with. Ended up buying a different brand battery 6 months ago. Watching them lying and threatening people for mentioning how bad their batteries are made me leave them a late review. I also just noticed they have alot of fake 5 star reviews that they must've bought all coming in with in a week by "people" who just paste generic info. Head to - product review:com:au and search dcs and you'll find out the their security system has blocked all the fake 5 star reviews and they in fact do have garbage product.

I recently switched to DCS batteries for my RV, and I’m beyond impressed. The quality is exceptional, and they hold a charge much longer than my previous batteries. Highly recommend!

Lies Lies and more Lies.
Lies, changes warranty after sale and lied about TOS Changes. Do not buy from this company!
Not to mention when they got exposed for this they sue the people responsible. All employees involved in this should be in jail.
