Looking at readily-available and fairly inexpensive Duracell and Crown GC2 batteries, same price and AH ratings, Crown is a couple of pounds lighter. Which to buy and why? Lithium isn't feasible right...
My first pair were Duracell from Sam's and they did real well even thought a wiring deficiency kept me from being able to recover the change as fast as I would have liked. As built, the converter/charger was too far with wire too small. When I fixed that they were great for a number of more years.
You really need a Victron or Bogart battery monitor to use them effectively.
