Most vehicle batteries last four to five years, but you should have it examined at every oil change — whenever your hood is opened. At that time, your Computerized AutoPro technician will inspect your battery’s terminals for corrosion and cleanliness.
It's worth noting that many Apple Stores allow walk-in customers to wait for a Genius Bar appointment on the spot, but only if the queue is short enough, so booking a reservation in advance is recommended.

These devices generally cost between $30 and $120. The prices vary with the brand and the number of output and charging settings provided. You can purchase one at any automotive accessory store. Most battery charger devices work with standard 12V car batteries, including deep cycle or gel batteries.
Before trying to recharge a battery with jumper cables, review these important safety tips.
The much larger point is, if you had even a basic comprehension on how rechargable battery backs work you would never find yourself in this situation. Its really not complicated. just remember like 3 basic things

We pride ourselves on not only being a cut above the rest, but leaders in our industry.
Measure the voltage of a repaired pack and check it again after 24 hours and a few days. If a cell drops lower than another in the pack, then there is fear of elevated self-discharge(See BU-802b: Elevated Self-discharge) Simple Guidelines when Repairing Battery Packs Only connect cells that are matched. Do not mix cells of different chemistry, age or capacity.Never charge or discharge Li-ion batteries unattended without a working protection circuit. Each cell must be monitored individually with a protection circuit.Include a temperature sensor that disrupts the current should the pack get hot.Apply a slow charge to a repaired pack to bring all cells to parity.Pay attention when using an unknown cell brand. Elevated temperature hints to an anomaly.Do not charge a Li-ion battery that has physical damage, has bulged or has dwelled at a voltage of less than 1.5V/cell for some time.Check a repaired pack for self-discharge. Intrinsic defects often reveal themselves in an elevated self-discharge. Previous Article Next Article
Many of these causes can be avoided, especially with proper maintenance. But a dead battery isn’t always preventable. Thankfully, unless it’s severely damaged, it’s easy to get your battery up and running again. Inspect the Battery
I have a PowerBook g4. The power port on My dc in power board where my power cord plugs in has gone bad. Apple doesn't make the part anymore so now I'm stuck with a computer that can't power up. I saw that they sell an external battery charger for all laptops. Is it possible to use my existing power cord and hook it up to my battery to charge it? If yes can you describe in detail how to do so?
However, if your device has been with you for more than five years and several issues are beginning to surface, a battery replacement can give a little boost to your iPhone’s performance, but it will further deteriorate. In this case, it might be better to get an upgrade instead.
battery charger works but when plugged in to computer the screen goes off but when removed the screen comes on
Next, do a function check. Are there any signs of corrosion? This negative reaction is unavoidable given the nature of chemicals present in batteries. However, one can always apply a protective layer to avoid battery leak (in case it eats away the case). If you scrub the terminals with Sodium Bicarbonated scrubbing tool, it can remove the corrosion away. Next, you should look for battery voltage. Low battery voltage is a red flag one should heed to condition your battery before it shuts down in middle of something important. HOW TO RECONDITION OTHER TYPES OF BATTERIES: Reconditioning your laptop battery
Give the battery another overnight charge as described in Step 6. The Epsom salts should remove deposits on the battery plates which previously prevented the battery from taking a full charge. Check the battery in the morning. If the battery still won't take a full charge, it likely cannot be saved. If the battery has taken a charge, replace the cell caps and use your cart normally. Put a trickle charger on the batteries every night to keep the batteries in peak condition. Use only distilled water inside your battery. Never use tap water as the chemicals in tap water will destroy your battery. Do not get battery acid or the white/yellow corrosion on the batteries on your skin or clothing as this acid can burn and destroy material in a very short time. Always wear gloves and eye protection when working on lead acid batteries.Always be sure to properly maintain your golf cart.
Sometimes, your battery may just need a boost instead of a replacement. Before you remove it, you can test its condition at a NAPA AUTOPRO service centre or at home with a battery tester or multimeter. If your battery can be saved with a boost, follow this guide.
