Early batteries were reserved for commercial use only, such as telecommunications, signaling, portable lighting and war activities. Today, batteries have become a steady travel companion of the public at large to reach a friend, they allow working outside the confines of four walls, provide entertainment when time permits and enable personal transportation. Best of all, batteries help in missions when people are in need.
Folks are eager to learn more about this wonderful portable energy device and one of the most common questions asked is, “What can I do to prolong the life of my battery?” SANNEW battery tell you how to care for your lithium batteries to meet their needs.
lKeep a battery at a moderate temperature. As food stays fresher when refrigerated, so also does cool temperature protect the battery by reducing internal corrosion, also known as parasitic reactions on the electrolyte and electrodes.
lAvoid deep cycling. Each cycle wears the battery down by a small amount and a partial discharge is better than a full discharge. Li-ion is maintenance-free and the battery lasts longest when operating between 30 and 80 percent SoC.
lAvoid abuse. Like a machine that wears down quicker under strenuous work, so also is a battery stressed by harsh discharges and rapid charges. Use cells that are optimized for the power and energy requirements as per application and increase that pack size to minimize load-related stresses.
lAvoid ultra-fast charge. Charge Li-ion Energy Cells at less than 1C (below rated Ah); Power Cells are more rugged and can be charged and discharged at a higher rate. NiCd is the only battery that can be fast charged up to 70 percent SoC without adverse side-effects.
lStore Li-ion at partial charge in a cool place. The worst combination is high voltage and elevated temperature. Store Li-ion at approximately 50 percent SoC.
Frequently asked question
1.How should I prepare a new battery?
Apply a topping charge before use. No priming needed
2.Can I damage a battery with incorrect use?
Keep partially charged. Low charge can turn off protection circuit
3.Do I need to apply a full charge?
Partial charge better than a full charge
4.Can I disrupt the charge cycle?
Partial charge causes no harm
5.Should I use up all battery energy before charging?
Deep discharge wears the battery down
6.Do I have to worry about “memory”?
No memory
7.How do I calibrate a “smart” battery?
Apply discharge/charge when the fuel gauge gets inaccurate. Repeat every 1–3 months
8.Can I charge with the device on?
Parasitic load can alter full-charge detection and overcharge battery or cause mini-cycles
9.Do I remove the battery when full?
Not necessary; charger turns off
10.How do I store my battery?
Store in cool place partially charged
11.Does battery heat up on charge?
Must stay cool or slightly warm
12.How do I charge when cold?
Do not charge below freezing
13.Can I charge at hot temperatures?
Do not charge above 50°C (122°F)
14.What should I know about chargers?
Battery must stay cool and no trickle charge when ready
