Battery IP Ratings And What They Mean
You may select the battery that provides you the greatest protection by understanding the ingress progression (IP) of that particular battery. All the batteries on which you so heavily rely should ideally be impervious to liquids and materials that could breach their barriers. Unfortunately, not all gadgets are resistant to substances like sand, dust, or water.
You can determine the degree of protection your battery has against both liquid and solid objects by looking at the IP rating supplied to it. Compared to vague phrases like waterproof, these ratings provide a more thorough and meaningful collection of facts. A battery's level of protection against the entrance of water and solids is indicated by the IP rating, which serves as a standard evaluation of battery inclosures.
How Do IP Ratings Work?
After the initials IP, there will be two digits indicating the ingress protection rating. Both the solid object rating and the moisture rating are represented by this string of integers. The battery's ingress protection level against solid items like dust is indicated by the first number. The amount of ingress protection against liquids like water is indicated by the second number. The protection against ingress, or the act of an item entering, increases with the numerical value.
The IP67 rating serves as an illustration of this. This battery would be perfect for use in maritime applications because it has an ingress protection rating of 6 for solids and 7 for liquids. This is due to the fact that the IP rating's first number, which stands for "ingress against solids," ranges from 1-6, with 6 being the highest attainable grade. The ingress rating for liquids ranges from 1 to 8, with 8 being the maximum attainable grade for intrusion against liquids.
A battery with an IP67 certification has the second-highest waterproof protection against liquids and the greatest protection against solids, demonstrating to the buyer that the battery will be extremely resistant to external incursions that might harm it.
The IP Rating Guide: How Does It Work?
As was mentioned before, the ingress rating takes into consideration protective classes for both solid object and liquid and moisture. Each of these two categories has a scale unique to it, and each category's value corresponds to a certain level of protection for the battery. The specifics of how each figure was calculated are listed below.
Solid Object Rating:
- Protection against large objects larger than 50 mm
- Protection against a large object larger than 12.5 mm
- Protection against a large object larger than 2.5 mm
- Protection against a large object larger than 1 mm
- Allows for very limited ingress of solid objects the size of dust particles. At this rating, the battery is protected well enough that the battery’s operations are not impacted by small particles
- No ingress of dust or small particles into the battery
Moisture Rating:
There is limited ingress with there being protection against vertical drops of falling water
In addition to the protection from vertical drops of water, there is protection up to 15 degrees from the vertical
- Protection against sprays of water up to 60 degrees from the vertical
- Protection from water from various angles
- Protection against strong jets of water
- Increased protection against stronger jets of water
- Protection when submerged in water for upwards of 1 minute and 30 seconds
- Protection against immersion in water under pressure for extended periods of time
Marine Applications and IP67 Rating
Particularly for maritime applications, the second number in the IP rating must be as high as possible, ideally a 7 or 8. This is due to the fact that batteries used in maritime applications are vulnerable to water jets, numerous angles of splashing, and the possibility of being completely submerged in water.
One of the greatest degrees of protection that an IP rating for both solids and liquids may provide is "IP67". With this rating, the client may be guaranteed that their product will be protected from liquid infiltration as well as moisture and liquids, even if it is submerged underwater for up to 1 minute and 30 seconds.
Batteries with an IP classification of IP67, such as BENWEI's LFP-512100-5 12V100Ah Lithium Deep Cycle Starting Battery, assist to entirely reject both dust and water infiltration, even when submerged in water for more than a minute. A maritime battery must be able to come into touch with water and debris without having its defences quickly penetrated. The IP67 classification for batteries used in maritime applications provides precisely this level of protection and is the industry benchmark.
The first lithium marine battery to be tested and authorised for outboard engines is the BENWEI LFP-512100-5. Lithium batteries must be certified with IP67 for Mercury.
