Optima RTS-3.7 for cars and vans
Rated 44Ah 12V 730A, the Optima RTS-3.7 replaces the original in plenty of cars and vans. With the positive on the left-hand side, the leads in most cars that used this code will reach without stretching. Searching by brand and reference beats browsing by photos, since many car batteries look identical.
For cars and vans, 44Ah is on the compact side. Hard starts are less likely with 730A on tap.

Fitting and everyday care
Short school runs and supermarket trips never give a car battery the chance to refill properly. Drive for at least twenty minutes after fitting to let the battery settle in. A swollen or cracked case means the battery should come out straight away.
The spiral-cell AGM technology explained
Each spiral cell is wrapped in its own glass mat, AGM style. Off-road vehicles love spiral cells for vibration resistance. A deeply flat spiral battery may need a charger that can start from low voltage.
Five checks for a perfect fit
- ✓ The technology is spiral-cell AGM. Keep the same type as the original, and confirm your charger offers a matching profile.
- ✓ Tape measure time: 237 × 172 × 197 mm is the footprint and height of this case. Leave a little clearance for the clamp and the cable lugs.
- ✓ Terminal layout: positive on the left-hand side. If your original is the mirror image, choose another reference rather than stretching the leads.
Frequently asked questions
Is there a barcode on the Optima RTS-3.7 I can check?
Yes, 4016987113554. Use it to cross-check with your records or a workshop order.
How can I be sure the Optima RTS-3.7 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.
