What is 115D31L battery?
Batteries for Asian cars are produced according to a single standard: JIS D 5301: 2016. It was designed specifically to make it easier for customers to choose a battery to replace the old one, since there are no more than 20 markings in this standard.
Batteries may differ slightly in their characteristics, for example, Solite 115D31L has a capacity of 95 A / h and an inrush current of 750 A, while American 115D31L has a capacity of 100 A / h with a cold scroll current of 800 A. Moreover, both of them can be installed on vehicles suitable for batteries marked 115D31L.
There are constant parameters, namely the dimensions and the presence of the type of ASIA terminals. Moreover, depending on the letter L or R at the end, it will depend on what kind of polarity it is.
Explanation of the battery 115D31L and 115D31R
The number 115 encrypts the value of the capacitance and inrush current. To calculate it, a complex formula with several coefficients is used. This indicator is crucial when choosing a battery for a car.
The letter "D" is a form factor, in this case - height - 225 mm, width - 170 mm. It is worth noting that for different manufacturers these figures may differ by 2-5 mm. These errors will not prevent you from installing the battery in the engine compartment.
The length of the case is indicated by the number "31", located after the "D". She is exactly 31 centimeters. The lettering “L” indicates reverse polarity: the negative terminal is located on the left. The letter “R” indicates that the 115D31R battery has the right polarity. Moreover, such batteries with direct polarity are quite rare.
Additional designations SMF or CMF indicate that the battery is leakproof and maintenance-free, that is, there is no access to plugs and water cannot be added to it. MF says that it is low-maintenance, you will have to eat from time to time to monitor the level of electrolyte.
General characteristics of the battery 115D31L / R
These batteries are very heavy and are always equipped with special convenient handles. Enclosure with increased strength and protection against mechanical damage.
General characteristics:
| Characteristic | Values |
|---|---|
| Capacity | from 80 to 100 A / h |
| Starting current | from 780 to 900 A |
| Reverse polarity | L |
| Direct polarity | R |
| Height | 225 mm +/- 2-3 mm |
| Width | 170 mm +/- 2-3 mm |
| Depth | 310 mm +/- 2-3 mm |
| Encountered Technologies | Ca / Sb, Ca / Ca, AGM, EFB |
| Serviced | Mf |
| Maintenance free | SMF, CMF |
| Weight | 20-25 kg |
The batteries are also resistant to high temperatures and strong acids. The AGM and EFB versions have a protection system against leakage of electrolyte in an inclined position.
