Your questions answered
What family does this battery come from?
It belongs to DCG Series. If you need a different size with the same construction, look within that range.
How can I be sure the Fullriver DCG120-12B is compatible?
Compare four things: the voltage, the amp-hours, the outer dimensions and which side the plus post is on. If all match, or capacity is slightly higher, it is a suitable replacement.
Can I order a battery for boats and motorhomes at baterias.online?
Only a few minutes once you have checked the figures and the code.
I cannot read the label on my old battery. What now?
Most makers print the code on the lid or side label, close to the brand logo. Type the brand and that code into the search box to land on the right page.
Care tips for AGM batteries
Glass-mat batteries are sealed, with small valves that only open if pressure builds up. Wheelchairs and scooters often use AGM for clean, sealed power. Old-fashioned chargers without automatic cut-off are a poor match for glass-mat batteries.

Practical advice for boats and motorhomes
A motorhome parked on the drive slowly loses charge to its alarm and tracker. Protect every terminal with a boot or grease and use tinned cable lugs aboard. A battery that will not hold the fridge through one night needs replacing.
