Werker Batteries???

Billsnp5, thanks for the info that's just what I was looking for. I have room to install 4 of them. We do a lot of off grid camping but not for more then 3 days, I do have the on board generator and a little solar (85 watt) my batteries are about 5 years old now, I mite give them a try.

I am in the UPS (Uninterruptible Power Supply) business and we use thousands of the standby batteries. These are made for systems where you might place up to 40 Jars (batteries) in a series to make up to 540Volts DC. These type of batteries are usually more expensive than most other batteries because of the systems they are used for. I have been using standby batteries that we might take out of systems in my Bass Boat for the trolling motor for over 3 years at a time with no issues at all. That is in a boat that might be on a trailer for several thousand miles along with being on the Columbia river in 3 ft swells at 20 miles an hour or 1 foot swells at 60 miles an hour for extended periods of time with no issues. I have not used them in my camper yet but when it comes time to replace my batteries I will be using some of these batteries for that. The main issue I see with the ones you want to use is they are only 80 amp hour batteries and I would want at least 100 amp hour but that is just if you need a lot of off grid power. I do have some friends that use some my old 125 Amp hour standby batteries in their big coaches with no issues at all. Werkers are made in Chine and are not he very best standby battery but in our history of using them the 80 Amp Hour batteries are very good. These are VLRA AGM batteries and are non spill-able so you do not have to worry about checking the water and cost over $150 each new. If the price is right, they are not swollen, have been on charge within the last 6 months, 80 Amp hour is enough for you and they are not very old I would not hesitate to use them. The date code on the Werkers is stamped on top of the battery in very small letters. You can google Werker date code to decipher the
code to tell the age of the batteries. Also make sure voltage is at least 12.5 VDC. It is not good for them to sit very long in a discharged state.
