Introduction

The purpose of this article is to give insight about issues and solutions regarding battery usage in Jimnys.

Standard battery in petrol Jimnys

• The standard battery type, as fitted to all petrol versions of the Jimny from 1998 to 2018 is an 054.
• The dimensions are 196L x 127W x 223H.
• The terminals are Japanese post type with the positive terminal to the right of the negative as you hold the battery with the terminals closest to you.
• The 054 is a common battery type used on many small Japanese and Korean cars.
• It is readily available from car battery suppliers and typically inexpensive.

• The performance of batteries varies between manufacturers.
• Typically the lowest performing 054 batteries have a capacity of 30 Ah and CCA rating of around 260 A.
• This adequately meets the standard electrical load requirements for the Jimny in a "normal climate".
• There are higher performing batteries of this size, up to approx. 45 Ah and approx. CCA rating of 400 A.
  • Higher performing batteries are even officially recommended by Suzuki (in the owner's manual) for "cold climates".

Solutions for higher battery requirements in petrol Jimnys

• In situations where higher electrical output may be regularly required (sustained winching for example), much higher spec or larger batteries should be considered.
• The standard battery tray in the engine bay can accommodate a slightly larger battery.
• Aftermarket battery trays that mount in the nearside of the engine bay offer the ability to fit a single large battery or to run a twin battery system.

Standard battery in diesel Jimnys

• Diesel (DDiS) Jimnys use much larger and more powerful battery as standard.
• The size of factory battery in DDiS Jimnys is approx 225L x 175W x 220H.
• Capacity in this size ranges from 60 Ah to 80 Ah, and CCA rating from approx. 550 A to 750 A.
  • The colder the climate, the more powerful battery should be used.
• This kind of battery should provide sufficient power of high power loads like winching.
  • Note that there is no space in the engine bay of DDiS Jimnys for an additional battery.
