The vent plugs minimize the risk of sparks that might be generated outside the car battery from entering the battery via the vent plugs.*
Utilizing Corrosion-resistant alloy
Minimize corrosion/degradation of metal exposed to air due to lowered liquid level (pole plate joints), and minimizing the occurrence of sparks.*
* Does not prevent all explosions, corrosion, breakage or sparks.
Reduces loss of electrolyte
Utilizing a two-step electrolyte loss control system
This battery uses Panasonic’s proprietary Two-step electrolyte Loss Control System.
Large Capacity (according to JIS performance rank)
Largest-level capacity in Japan, more than sufficient even for vehicles with heavy electrical demands.
The Panasonic’s JP Series uses high-density paste. The ratio of additives used in the negative electrode are optimized to achieve a large capacity.
Panasonic’s JP Series uses low-resistance carbon, which has a large reactive surface area, for the negative electrode additives. This greatly improves the quick charge performance on vehicle.
Grid of fine meshes
Panasonic’s JP Series uses a grid of fine meshes, which we have succeeded in further slimming using our in-house technology. The upper part of the grid, through which the current flows, is thick, while thinning the lower part makes it lighter in weight.
Silver alloy grid for long life
Highly reliable silver alloy is used for the grid raising its durability and heat resistance. The JP Series lasts 1.7 times longer than our SB Series.
Contribute to fuel efficiency
Reducing the weight of a car is very effective in improving fuel efficiency. automobile manufacturers strive to lighten all the parts used in cars. Panasonic has a long history of achieving light weight, as shown in the diagram. This technology is used in the JP Series to realize lightweight design of the highest level in Japan (comparison for the same performance rank). The quick charging performance on vehicle decreases the operating time of the generator in "charge controlled vehicle" reducing the burden on the engine yielding better fuel efficiency. The lightweight design and quick charging performance together contribute to fuel efficiency.
Good performance for "Charge Controlled Vehicles"
"Charge controlled vehicles" repeatedly charge and discharge their battery, placing considerable strain on it. Our JP Series car batteries allow quick charging performance on vehicle from nearly flat at the highest level in Japan. Their large capacity makes it difficult to over-discharge them and lessens the burden on the car battery itself, giving added reassurance when using it.
