type of battery -- mid 2010 13-inch macbook; and how soon do I need to replace dead battery?

The following site has a good reputation for Mac upgrades, does international shipping and has an international toll free number as well as online chat and may be a good place to get more information: http://eshop.macsales.com/item/NewerTech/BAP13MBU65V/

Be sure to correctly identify the MacBook model you have and also match the

battery part number with computer; since MacBook & MB/Pro are different.

From what I can tell, there is no listing at OWC macsales for a non-user

replacement battery, for MacBook7.1 13-inch Mid 2010 unibody white.

The battery requires a partial take-apart; see iFixit.com repair guides

online to tell how they are accessed. An Apple Store genius bar could

install a new battery for a fee over the replacement cost. ($120?)

OWC macsales has several models for certain MacBook & MacBook Pro portables

and offers correct tested RAM upgrade for specific models of Apple portable.

Note how to identify which MacBook model you have... see info on this page

http://eshop.macsales.com/shop/Apple/Laptop/Batteries by model identifier.

If the computer is a MB/Pro, then the battery part numbers could vary.

Good luck & happy computing! 🙂

PS: here's some other info I found, after my earlier post timed-out:

See how a determined DIY user with some skills & abilities could dissect & replace battery:

• Find an Apple Authorized Service Provider
• Visit an Apple Retail Store

An Apple Store or Authorized Apple service provider could replace the battery

for the cost of the part, and a fee for the tech time. This may vary by location.

Hopefully this helps. The part is not considered 'user replaceable' but it is possible.

Good luck & happy computing! 🙂

Are the batteries international or the difference in electrical current between USA and Europe can affect the battery?

The power adapter (Magsafe) is designed to be automatic within a certain range of

the electricity available from the power mains. So the battery sees that regulated

DC power as does the computer, from the automatic range of an Magsafe adapter.

That said, quality of replacement batteries may vary in so much as expected life

and use cycles; even ideally that depends on several factors. Not all replacements by

other manufacturers may be equal. And some have less capacity per charge than

the official original or official replacement part specification. A cheap replacement

may be half the battery life when compared to a quality replacement.

So that's something to research if looking at a bargain.

Also, finding a suitable replacement may take effort.

In any event...

Good luck & happy computing! 🙂
