Optima RTU-3.7 for cars and vans
Some drivers know their battery only as the Optima RTU-3.7 written on an old invoice, and that is enough. Rated 44Ah, there is enough reserve for the alarm, the clock and the odd evening with the radio on. Ordering from baterias.online works best with the old label photographed on your phone.
Compact by the standards of cars and vans, with 44Ah. A cranking figure of 730A is high for a case this size.

Installation and maintenance tips
Classic cars stored in a garage all winter are famous for flat batteries in spring. Clean any white crust off the clamps with warm water and a little bicarbonate before fitting the new battery. Interior lights that fade when the starter turns are another hint.
What spiral-cell AGM means for you
The unusual shape is the giveaway of a spiral-cell battery. Strong bursts of current make spiral batteries great for big engines. Check dimensions and terminal style carefully, as the case shape is unusual.
Make sure it fits your vehicle or equipment
- ✓ Check 237 × 172 × 197 mm against the tray, not just the old battery.
- ✓ Same box, opposite posts? Many sizes exist in both layouts. This one is positive on the left-hand side.
- ✓ 44Ah sets how long the battery can power things with the engine off.
