You are watching: What size battery does a pt cruiser take

Our first question comes from Van T., who says:

I have to replace my automobile battery (2005 PT Cruiser) and also want to download an Optima Battery, however I cannot find a fit. The factory battery is a 26R but my car has one aftermarket cold waiting intake, which permits much more room.

There are much more than 60 different BCI group battery sizes and unfortunately, OPTIMA go not sell what we think about "exact-fit" replacements because that every application. However, numerous PT Cruiser owners have used our batteries in applications that we think about "custom." When selecting a battery because that a practice application, that is important to consider the following:

Hood Clearance– There should be at the very least ¾” clearance between the height of the battery terminals and also the underside of the hood. When we perform our fitment research studies we placed a round of clay on peak of the post, and very carefully near the hood to make certain that nothing makes contact. By measuring exactly how much the clay is squeezed down when the hood is closed, we deserve to know exactly how much hood clearance us have.

Trunk/Interior Mounting– If your battery is placed inside the passenger compartment or trunk, the battery have to be vented come the exterior of the vehicle. Optima team 27, 51, 78, 34C, 31 and also H6 battery all have ports for connecting a vent hose.

Side Terminals– Optima 34/78, D34/78, 75/25 and D75/25 batteries have actually both top and also side terminals. If you room using one of these battery in a auto that uses the top terminals, that is necessary to ensure that the next terminals can not come into call with noþeles metallic (for example, the firewall or fender well), thereby causing a short. We suggest keeping the article protectors top top the terminals you space not using. Do not attach a winch come the next terminals.

Battery Modifications– Cutting, drilling, trimming or otherwise modifying your OPTIMA battery may present a safety hazard and will void the warranty.

Mounting– her Optima battery must be securely mounted. The terminals space not intended come be supplied to for sure the battery. Making use of the terminals in this means will damage the battery and void your warranty.

Heat– defend your battery indigenous high heat, such together turbochargers or exhaust manifolds

Our following question originates from Marc M., who asks:

I have a Ferrari 550 Maranello through a red peak optima battery installed, and also store the auto for the winter. Have the right to you recommend a battery maintainer because that the battery which stays in the car?

There room a lot of of great battery chargers, tenders and maintainers top top the market. Most of them will work just fine ~ above OPTIMA batteries. We"re clear partial toOPTIMA Chargers and also Maintainers, but the only kind of chargers to prevent are those designed for gelatin batteries, together those chargers will not fully-charge one OPTIMA and also could damages it end time. Likewise, “gel” or “gel/AGM” charger settings should additionally be avoided.

The ideal chargers space microprocessor-controlled and also there room two simple types of maintain chargers. Fully-automatic, "multi-stage" or "multi-step" chargers will certainly monitor the battery and charge it as necessary. Multi-stage maintainers will charge at differing voltages and also varying amperage (rarely exceeding 2 amps). Few of these multi-step chargers are likewise capable the being constant battery chargers (7 amps or more). These species of chargers are preferred.

Traditional "float" chargers provide constant voltage through tapering amperage come the battery, even when the is fully-charged. For float-charging, us recommend 1 amp max, 13.2-13.8 volts. These room OK too, yet the multi-stage chargers room a much better option.
