How to Extend the Life of Your Tablet with Replacement Batteries

Tablets have become increasingly powerful in recent years, but the batteries that come with them have failed to keep pace. Anyone who uses a tablet will be used to them running out of charge before the day is over. Since their functions draw so much power from the battery, they tend to run out quickly when used regularly. To combat this, there are a variety of different solutions available to keep tablets charged up throughout the day. Most of these will involve using an external charger - wall chargers, car chargers, and portable chargers are all options. However, for these to work, a power source is needed, whether this be a wall power socket, car battery, or laptop. An alternative option, therefore, is to buy replacement and backup batteries. When the tablet dies, the battery can simply be taken out and swapped over with a new, fully charged one, although this will depend upon the tablet itself and how accessible the battery is.

About Replacement Batteries

Tablets use Li-Ion and Li-Poly batteries. These batteries are environmentally friendly, have good charge capacities, and are very sleek and small. This is especially the case with Li-Poly batteries as they don't have an outer metal casing. Like pretty much all mobile and tablet batteries, however, these are prone to wear and tear and, after several hundred charges, they will run down and become unusable. Depending on the user, the battery may last for the lifespan of the tablet, especially for those who replace their tablets and other devices regularly. Many people, however, will find that their batteries begin to lose charge quicker as the months and years go by. When this happens, the importance of having replacement and spare batteries heightens.

Replacing Your Tablet’s Battery

Tablets are generally sealed and, depending on the specific make and model, it can be very difficult to actually swap over a battery quickly and easily. The same is generally true of modern phones: these are sealed up in many cases and this makes changing batteries a difficult talk. Old phones, on the other hand, could easily be clicked open with minimal effort; making changing batteries simple. As mentioned, the type of tablet being used will determine how easy it is to swap batteries over. In some cases, special tools and skills are needed. As such, the option of swapping batteries back and forward might be unrealistic with certain tablets.

Backup Batteries Provide a Solution

One solution to this problem is to buy backup batteries to be used with the tablet. These can be bought to be compatible with any tablet on the market and will help to provide extra charge from an external source when the tablet runs low on power. Backup batteries come in a range of different sizes, but each of them will be measured in mAh, or milliamp hours. Tablet batteries will also be measured in mAh, so this makes it easy to quickly work out how much charge the backup battery will provide. For example, a tablet with a 1500 mAh battery will get more than 2 charges from a 3500 mAh backup battery. Bear in mind, however, that about 20 per cent of any mAh rating should be discounted due to inefficiencies.

Choosing the Right Backup Battery

When choosing a backup battery for a tablet, it is important to juggle size, charging time, power, and convenience. Small batteries will be easily portable and convenient to carry around, but will have lower power ratings which may only be enough to offer a tablet an additional 30 or 40 per cent charge. Larger batteries, however, will have higher mAh ratings, and will for this reason provide a tablet with a lot more charge. This might be up at several full charges before the backup battery needs to be recharged itself. As such, it all depends upon personal preference. Larger batteries will also take a longer time to recharge, but will not need to be recharged as regularly. For travelling purposes, smaller batteries might be more suitable, but for regular use at home and work, larger, more powerful ones, might be better.

Buying Replacement Batteries

When looking for replacement batteries, there are several factors that need to be considered. First and foremost, it is important to ensure that they will be compatible with the tablet itself. When buying replacement batteries to be installed into the tablet, check the spec carefully and make sure that it will work properly. When looking for external backup batteries, make sure that it has all of the necessary connection leads to fit the tablet - often universal batteries are best, as these have ports for a variety of different brands of tablet and phone.

Branded of Unbranded?

It is also sensible to look at whether the battery is branded or unbranded. In other words, is it made by the official manufacturer, or is it made by a third party manufacturer? Price will often give this away, with branded products generally more expensive. When shopping, consider both options, but be wary of very low priced, but seemingly high quality batteries. There will be a reason why these are being sold so low, and this will usually be because they are made with low quality materials by companies with loose quality controls in place during the manufacturing process. Consequently, these batteries may be more prone to defects and other such issues. In the case of replacement batteries, this may actually cause damage to the tablet itself, something which may void its warranty. To be safe, therefore, it is often better to choose batteries and backups sold by official manufacturers and brands.

Buying Replacement Batteries on eBay

When it comes to shopping for replacement batteries and backup batteries, eBay is the place to go. The first thing to do is to determine what batteries to search for - in this case, will it be a replacement battery to store in the tablet or an external battery pack to use to charge the tablet when needed? Next, search for listings. To do this, go to the homepage and then find the category called Electronics & Technology down the left. After this page loads, look for the next category called Mobile & Home Phones, followed by Mobile Phone Accessories. On this page a list of smaller accessory categories will load - look for the one marked Batteries. Within this category it will be possible to find backup batteries that are compatible with both mobile phones and tablets - to do this, simply type 'tablet batteries' or some approximation of those words into the search field at the top of the page. Alternatively, go back to the Electronics & Technology category and then search specifically for Computers/Tablets/Networks, and then iPad/Tablet/eBook Accs. Within this category, turn again to the search function and type in 'tablet replacement batteries' or some similar words. Now it will simply be a case of searching for appropriate listings on the page. In addition, other features down the left can be used to help narrow the search - such as searching by Brand, Condition, and so on.


Most tablet batteries have a half-life of about 2 years. After this time they will begin to function very poorly, and may suffer some wear and tear in the months leading up to this point as well. This will depend upon the amount the tablet is used, and the number of charges it goes through. When a battery begins to perform poorly, it may be time to get a replacement. Some tablets are more accessible than others in terms of using replacement batteries to swap in and out when needed. Those that are fully sealed, however, may need special tools or skills to access them. As such, changing a battery can be a difficult task, and this may necessitate some professional help. As an alternative, backup batteries provide users with the ability to charge up their battery using an external battery pack. These will vary hugely in power, size, and convenience, so it will be down to the user to determine which works best for them. When shopping for either replacement or backup batteries, use eBay to find a host of listings. When doing so, carefully read descriptions and look at seller feedback to ensure that the battery is of a high quality, and the seller is trustworthy.
