Batteroo Boost Best Practices

Batteroo Boost Best Practice/Getting Started Guide

Issue: What’s the best way to put the Batteroo Boost reusable sleeve into a device?

There is no single way that will work for every battery compartment out there. But there are a few commonly used types that we can make recommendations on how to use the Batteroo Sleeve.

The Batteroo Boost sleeve adds just 0.35 mm (thickness of a fingernail) to the length of the battery, and only 0.12 mm (thickness of a human hair) to the thickness of the battery, and uses the space around the button of the battery for its circuitry. These are small enough increases that the Batteroo Boost fits without issue in many products, but may still be a tight fit.

In order to be successful in inserting the Batteroo Boost, one should:

• Insert the sleeve around the battery first with the battery outside of the device.
• Put the battery with the sleeve on into the compartment with the negative/flat side in first.
• Press down on the side with the spring of the battery compartment and push it as far as possible. Since you were pushing down, your thumbs would be on the top side of the battery holding the top of the sleeve in place.
• Now push the top sideways by sliding the top towards the positive side of the battery compartment.

For better understanding, see our illustration and our short video on our website.

Batteroo Boost Troubleshooting Guide

Issue: Battery and Batteroo Boost together are very tight fit in my device. Is this going to damage my battery compartment’s spring?

The compartments of battery-operated devices are designed not only to fit the batteries, but also to make sure it is a tight fit. That way the battery is always making a connection and it is not loose. So, when Batteroo Boost was designed, a lot of effort went into making them extremely thin as to fit into most devices. The Batteroo Boost sleeve adds less than 0.5mm (0.35mm) to the length of the battery. To put things in perspective, it is roughly the thickness of a fingernail. While it is a small amount of space added to the length of the battery, that extra needed space is accommodated by extra compression of the spring in the battery compartment; therefore, a tight fit is to be expected and is normal. It is also noteworthy that a tight fit would not have a negative effect on the spring in the device or the operation of the circuitry.

Issue: Battery and Batteroo Boost together are too large to fit in my device. How can I put them in?

The Batteroo Boost sleeve adds 0.35 mm (thickness of a fingernail) to the length of the battery, and adds 0.12 mm (thickness of a human hair) to the thickness of the battery, and uses the space around the button of the battery for its’ circuitry. These are small enough increases that the Batteroo Boost sleeve fits without issue in many products. However, there are products with battery compartments that are barely able to accommodate a battery and have zero additional space for anything else. So, while we have made every effort to fit as many devices, there will be devices that will not accommodate Batteroo Boost.

Additionally, some battery-operated devices have a pair of plastic guards around where the positive button goes. These plastic guards are meant as reverse polarity protection; that means that if someone inserts the battery upside down, there would be no electrical connections made. However, these guards are sometimes made larger than needed. In some remote cases, these guards can stop the Batteroo top spring contact to not make connection with the positive contact of the battery-operated device. As we identify these devices, we are going to have communication with their manufacturers to improve on their design parameters. We have been able to shave the plastic guards down and get the device to fit, but don’t recommend that to be tried at home.

Issue: My device won’t turn on when I use Batteroo Boost. What can I do?

• Remove, check battery polarity to make sure Batteroo Boost is put on the right way on the battery; the nipple side of the battery is covered by the top part of the Batteroo Boost sleeve. Reinsert and check.
• Check that the battery with the Batteroo Boost sleeves inserted with the correct polarity shown within the device. In other words, the battery is plugged into the device with plus side going to the plus side of the battery-operated device. Reinsert and check.
• Check visually to see if the top and bottom contacts are making a connection. Some battery-operated devices have a pair of plastic guards around where the positive nipple goes. These plastic guards are meant as reverse polarity protection; that means that if someone inserts the battery upside down, there would be no electrical connections made. However, these guards are sometimes made larger than needed. In some remote cases, these guards can stop the Batteroo top spring contact to not make connection with the positive contact of the battery-operated device.
• If you are using a “Dead” battery, it could be that is completely dead. Try a new battery to see if it works. That way you can be sure the connections to the Batteroo Boost are not the cause of the issue.
• The side portion of the Batteroo Boost is coated with insulating material. While unlikely, a very small percentage of Batteroo Boost sleeves may have a tiny bit of the insulating coating from the sides inadvertently covering the bottom contact causing the connection to the bottom not to be as good. This may be visible as a dark haze on the bottom section towards the battery end. Gently scraping the bottom tab clean with a screwdriver can remedy the intermittent connection the coating may have caused.
• If the issue of the device not turning on happens after you have tried the Batteroo Boost on other batteries earlier, it may be possible that the top spring contact is flattened. Please see the issue and solution below.

Issue: My Batteroo Boost spring contact is smashed flat.

The springs are made from Stainless steel and are meant to be spring like and flexible; but some devices are so tight that the spring contact is pushed beyond the point that can spring back on its own. Simply take a small flat-head screwdriver or other thin pry-tool and carefully bend up the fingers of the spring contact. Try re-inserting the Batteroo Boost and check.

Issues Removing Sleeve From Products:

Issue: My Batteroo Boost and Battery are stuck. How do I remove them?

There are couple of cases you may be referring to. In some applications like a flashlight where two batteries are inserted in a tube shape compartment, to get the second one out, simply tap on the flashlight housing and the battery/Sleeve would slide out.

A second case where the battery and the Batteroo Boost sleeve is in a compartment that is accessible from the side, see if you can remove the battery and the Batteroo Boost at the same time. While that is not necessary, that would make it come out easier. If you just pull the battery out, the pressure of the spring tends to push against the Batteroo Boost and bend it upwards. Batteroo Boost is micro thin and has very little structural integrity, so it will bend easily. However, if you carefully remove it from the compartment there will be no damage to the Batteroo Boost as its circuitry is at the top.
