Questions buyers ask about the Ritar RA12-120S
How long does ordering take at baterias.online?
Only a few minutes once you have checked the figures and the code.
Which code identifies my existing battery?
Use a tape measure and the handbook: the factory fitment listed there tells you which code to search.
Will I need help carrying this battery?
At 29 kg, one person can usually manage with care; bigger batteries are easier with two.
Can I keep the Ritar RA12-120S on a shelf before fitting?
Yes, gradually. Lead batteries lose a little charge each month, lithium much less. A quick charge before use is a good idea.
AGM: how it works
Lead plates in AGM batteries are often slightly thinner than in flooded types. Ambulances and police cars use AGM for their heavy electrical loads. Check that the vent hose is connected if the battery sits inside the vehicle.

Installation and maintenance tips
A yacht on a mooring all winter needs its batteries checked before launch. Protect every terminal with a boot or grease and use tinned cable lugs aboard. Leaving the charger on the wrong chemistry setting can quietly overcharge or undercharge a whole season.
