Batteries Flat
Using appropriate loading methods for your battery
Much of the reliability and longevity of a battery depends on the quality of its charger. In a highly competitive market, shippers often have low priority, especially for consumer products. In this article, we conclude that the charger is essential and guarantees the protection of the compaq presario v2000 battery . We focus on methods recommended load to increase performance of battery packs NiCd, NiMH and Li-ion.
A battery should not become warm during charging because high temperatures shorten their life. However a certain temperature rise can not be avoided especially when charging batteries nickel. The temperature reached a peak when the battery reaches full charge, then reduced slightly when the battery goes into charge mode at low speeds. The battery should eventually return to room temperature.
If the temperature remains consistently above the ambient temperature after a few hours in a ready mode, the charger does not work correctly. Remove the battery when it is ready for any prolonged trickle charging will damage the battery. This warning applies especially to NiMH battery,because this chemical does not absorb much torque overload.
A Lithium Battery should never become warm during charging. If this occurs, the battery or charger is defective. Stop using them.
Chargers nickel are grouped into three categories:
Slow charger - The slow charger, also known as the 'overnight charger', applies a fixed charge of about 0.1 C * (one tenth of the nominal capacity) until the battery is connected. The charging time is 14 to 16 hours. The slow chargers come with cordless phones, CD players and portable consumer products.
Quasi-fast charger - The quasi-fast charger has a place in the middle range, both in terms of charging time and price. Charging takes between 3 and 6 hours and the battetry switches to trickle charge when it is in state 'ready'. Quasi-fast chargers accommodate a Nickel or lithium and those are used with professional products such as cellular phones, laptops and camcorders.
Quick Charger - This charger offers several advantages, the most obvious one is load duration smaller. At 1C, a flat apple a1185 battery NiCd or NiMH usually loads in less than an hour. Accurate detection of full charge is important. Once the battery is fully charged, the charger switches to regime filler then trickle. The rapid chargers are used with industrial equipment such as transmitters - receivers, medical equipment and portable tools.
Simple guidelines:
-A charger designed for NiMH battery can also accommodate NiCd, but the reverse is not true. A charger designed for NiCd NiMH battery overload.
The nickel-battery fast charging prefer because it reduces the crystalline formation (a process known as "memory")
The nickel-and lithium batteries require different charge algorithms. These two couples chemicals are not normally interchangeable on the same charger.
If she is not used so often, remove the battery from its charger and use a filler before use. Do not leave the vgp-bps2c battery in standby mode in the charger.

Phone battery: Condition it or never let it go completely flat?
I just got a brand new Nokia E63 and was wondering:
Do I let the battery go completely flat, then charge it for 12 hours (conditioning the battery), like has been suggested for some batteries?
-or-
Do I never let the battery go completely flat, like has been suggested to do with other batteries?
Batteries will always wear out eventually, today, on most of the "good" ones it doesnt matter how you charge it, tho keeping it in the charger 24/7 still could damage it I guess, but other than that based on what I've read it doesnt really matter.
