How do I identify my battery?

The first information to provide would be the make and model of the equipment that you require the battery for e.g. Toshiba Satellite A105, or Compaq Presario CQ60. There is also usually a label on the original battery which will provide a battery part number.

What if I can't find my exact battery on your website?

If you cannot locate your battery by your laptop model, please look up and search by your original battery part number. Our compatibility listings are constantly being updated and not all laptop models may be listed. If you cannot find a battery by the laptop model or battery part number, please call one of our expert laptop battery sales person and we will be happy to assist you in finding your laptop battery.

How long will the new battery power my laptop?

Actual battery run-time depends upon the power demands made by the equipment such as the applications you are running and your laptop settings. Our replacement batteries will last the same or longer than the original battery which came with the laptop when it was brand new (at the same capacity). Generally, a standard 4400 mAh will last between 45-90 minutes. You can calculate how long a higher capacity battery will last based on the mAh difference. A 7200 mAh battery will give you 64% more run-time, and a 10400 mAh will give you 136% more run-time than the 4400 mAh on a single charge.

I have seen different battery cell types like 6, 9, and even 12 cells, what are they?

The more cells in a battery, the more run-time you will get with the battery. Generally, the battery with the lowest number of cells is the standard battery that came with your laptop. The 9-cell or 12-cell batteries are the extended, higher capacity batteries that will provide you much longer run-time on a single charge.

Will the higher capacity work with my laptop?

Yes. We guarantee that it will fit, work and is 100% compatible with your laptop. Our high capacity batteries have the same voltage and will work like your standard battery except that it will provide you much more run-time. However, in order to house the extra battery cells, most higher capacity batteries will be physically larger and may lift or stick out of the back of the laptop.

How long do typical batteries last?

The life of a battery under normal use is around 500 to 900 cycles (one full charge-discharge is considered a cycle). For the average user, the life of a battery will be between 12 to 18 months. However a more avid user might get less of a life span due to the frequency of charge/discharge cycles or improper care of the battery, and a user who rarely charges/discharges a battery will get longer life from the battery. As a rechargeable battery begins to fail, the run-time of the battery on a full charge will also begin to decline. When a battery supplies 30 minutes or less of charge, it is time for a replacement.

What is a "smart" and "dumb" Battery?

Smart batteries have internal circuit boards with smart chips which allow them to communicate with the notebook and monitor battery performance, output voltage and temperature. Smart batteries will generally run 15% longer due to their increased efficiency and also give the computer much more accurate "fuel gauge" capabilities to determine how much battery running time is left before the next recharge is required.

Is a 11.1v or 10.8v battery compatible with a 14.4v or 14.8v?

No. The voltage of a replacement laptop battery must be within a reasonable range. A replacement laptop battery should always be within +/- 1V. Anything above that range may cause incompatibilities.

What are watt-hours, volts and milliamp-hours?

Every battery has three ratings which are watt hours, volts and milliamp-hours.

Watt Hours (wHr) is a unit of energy equal to the work done by one watt acting for one hour and equivalent to 3,600 joules. The wHr is a calculation of voltage and mAh.

Milliamperes (mAh) is a unit of measure electric power over time. It represents the total amount of energy store in your battery. The mAh rating is also a measure of the number of hours a battery may last. The higher a battery's amp hour rating is, the longer the battery's run-time will be. It is not uncommon for some of our batteries to have higher or lower amp ratings. This will not cause any incompatibilities.

Voltage (V) is the amount of electricity that is delivered to your computer. The amount of energy from your wall outlet is greater than what your laptop needs to operate. Therefore a power adapter contains a box like bar that will decrease the energy lowering the voltage rating. Each computer manufacturer designs their computers for the appropriate voltage requirement. Your battery pack will then be engineered to match the voltage of the power AC adapter. Laptop battery packs are composed of several battery cells that are wired together in series. While the voltage of the Hi-Capacity battery may not be identical to the original battery, the voltages must be within a reasonable range. Any replacement laptop battery should always be within +/- 1V. Anything above that range may cause incompatibilities.

Are your batteries new or refurbished?

All of our batteries are brand new. We do not sell old, used or refurbished battery cells. We use only the best battery cells, grades and components in all of our batteries for you safety and value.

Is there a difference between your battery and an OEM battery?

No. We use the same quality components as laptop manufacturer's use in their batteries. The only difference is that our batteries are not labeled or branded.

Why is the price of your battery so much lower than the brand names (OEM)?

We specialized only in laptop batteries and work closely with the manufacturer to produce only the highest quality batteries. Only name brand battery cells and circuit boards are used in our batteries. Our prices are so much lower than OEM batteries because we manufacture our own casings and cut out the costs to brand or label our batteries, which in turn reduces any additional cost to our customers

Do you have a 60-Day Money-Back Guarantee?

Yes. We offer the only 60-Day money back guarantee on laptop batteries, so that you can shop with confidence. If you are not happy for any reason, you may request for an exchange or a refund. Please view our Return Policy for more details.

How does your Warranty work?

We stand behind all of our laptop batteries and if your battery fails or does not hold a charge for 30 minutes during the warranty period, we will replace it with a brand new battery. Please view our Return Policy for more details.

Is there a difference in your 1-year and 2-year Warranty batteries?

No. Our 1-year and 2-year warranty batteries are the exact same product. We offer and extended 2-year warranty for only $20 more on all of our laptop batteries.  If you are a traveler, professional user, or just constantly run your laptop on battery power alone, you will have a much shorter life expectancy on your battery. With the extended 2-year warranty, you can replace your battery at only a fraction of the cost of buying a new battery.

Will using your battery void the warranty for my laptop?

If your laptop is still under warranty, we recommend that you contact the laptop manufacturer since your original battery should still also be under warranty. You can use our batteries with confidence, as we offer a 60-day money back guarantee, and all of our laptop batteries come with a $100,000 Equipment Protection Plan which automatically covers you up to $100,000 from any damage to your device on batteries and/or chargers purchased from This Equipment Protection Plan is free and is valid for the duration of your warranty period.

Do you price match?

Yes. We guarantee the lowest prices available on the internet and will beat any competitor's price. We offer the highest capacity and quality of laptop batteries at the lowest prices. If you have found a website selling a battery with the same high quality and grade and offering the same warranty, give us a call and we'll beat any legitimate prices. When you are comparing prices, the total should include the cost of your purchase for the exact same product, plus any shipping/handling, and taxes. (Please note, our customers do not pay taxes unless the ship to address is located in California). In order to give you the best battery available, we cannot always beat prices from auction web sites, free offerings, and certain shopping clubs. These prices are lower because they are selling a much more inferior, refurbished or recycled battery.

Note: When doing a price match, we will verify the following:
1. The battery cell manufacturer must be listed
2. Battery grade must be listed as "Grade A”
3. Battery must be offered with the same 1 or 2 year warranty

What kind of care does a new battery require?

Your battery will need some attention as soon as it arrives. Batteries come in discharged condition, and must be charged before using. The battery should be cycled (fully charged for 12 hours and then fully discharged) 4-6 times initially to allow it to reach its full capacity. Sometimes your laptop's charger will stop charging a new battery before it is fully charged. If this happens, simply remove the battery from your laptop and then reinstall it. The charge cycle should start again. This may happen several times during your first battery charge. Don't worry, it's normal. Some laptops have been prone to reject third party batteries if they have an old BIOS software version installed on the laptop. If your laptop rejects your new battery you will need to check your laptop manufacturer's website for system BIOS software upgrades. Once that is done, your battery needs only minimal care. Lithium-based batteries should be given a full discharge/charge cycle once every 30 charge cycles. If you’re not going to be using it for 4-8 weeks or longer, we recommend you remove it from the laptop and store in a cool, dry location. A recharge may be necessary when you’re ready to reuse it. Another recommendation: let the battery discharge over 50% before recharging. This practice lets you access the full potential of each battery charge. If you don't do this, charges may eventually be reduced by as much as half of their capacity.

I don't unplug my laptop from the wall outlet very often; will it overcharge or harm my battery?

Leaving your laptop plugged into a well outlet for long periods of time deteroriates the life of the battery. We suggest using it on battery power, draining it to 10% then recharge the battery. If you are plugged in at all times, to save on battery life, we suggest removing the battery and use the laptop on AC power only.

If lithium ion batteries have no memory, why do I have to cycle, condition or calibrate the battery?

A battery needs to be recalibrated from time to time in order to keep the battery indicator percentages and time left accurate, and to keep the battery operating at maximum efficiency. You should recalibrate your battery upon first use and then every few months after that. If you normally leave your laptop plugged into your AC adapter, and very rarely use the laptop on battery power alone, you should perform this process once a month.

If you have spare batteries, rotate them regularly so they all stay active and avoid over-discharge. It is recommended to charge and use batteries at least every three months. Batteries should not go without reconditioning (recharging) for more than 3 months, as they may reach a deep discharge state and may not be able to charge up again.
