This guide will discuss some potential causes and solutions for the error code "88" with the EWI5000.
The 88 error code typically indicates a problem with the battery. This could range from the battery not being seated properly, to the battery being unable to retain a charge.
The EWI5000 uses a lithium-ion battery, which is found in a large variety of consumer electronics, such as smartphones and tablets. These batteries are light, charge quickly, and stay charged for a relatively long period of time. They do not have a "memory", meaning they do not need to be completely discharged before charging up again fully.
As with anything, there are limitations. It can be damaging to allow the battery to completely discharge, even causing the battery to be unusable. The batteries are also sensitive to extreme temperatures, so exposure to an extremely hot or cold environment can cause the battery to drain faster and affect its overall lifespan.
It's a common misconception that it is better to allow a lithium-ion battery to die entirely before recharging in order to prolong the battery life. The EWI5000 will indicate that the battery has reached a low charge by flashing the Preset LED or User LED lights. If you get this notification, it is highly recommended to plug the battery in to charge as soon as possible. Lithium-ion batteries will always drain, even if not in use, so it's important that they are not left to sit for any amount of time at a low charge.
It is not recommended to leave the EWI charging for long periods of time. While it is great to make sure the battery retains a consistent charge, leaving it plugged in for any time over a week can be excessive and bad for the battery's health. In fact, the high temperature caused from overcharging can lead to the battery deteriorating from the inside, which will affect the batteries reliability and amount that it will be able to charge in the future.
If the battery or EWI begin to feel hot while charging, disconnect the EWI immediately to avoid any damage.
It is recommended that you remove the battery and store it in a safe place if it will not be in use for a long period of time. When doing this, it is recommend to leave the battery about 50% charged.
It is important to make sure that the battery is removed and replaced carefully to avoid any damage to the battery or EWI.
Other factors that can affect the battery are the environment the battery or EWI is stored or used in. As discussed before, the battery is sensitive to extreme cold or heat, as well as moisture. We always recommend to use, store, and charge the product at room temperature.
The EWI5000 is capable of being charged by the available USB cable and wall charger, as well as an available USB port on your laptop. The charger should provide a 5 volt, 1.5 amp output to charge the battery. A laptop should also provide this current but can be subject to other factors and may be more inconsistent based on make and model. More or less, if the laptop is not plugged in or is hosting several other USB devices, it may not be sending the proper volatge to the battery, thus affecting it's charge. In some cases, the battery may not charge at all.
Depending on the cause, which is much harder to determine, there is a broad range of options we can cover to troubleshoot the 88 error:
The best way to prevent further issues is proper care and maintenance for your product and its battery. Here is a quick review of some of the information we've covered and some more tips to preserve the battery life:
