Perhaps you’ve apparent the advertisement: an Optima array survives the rigors of a annihilation derby, again goes into the agent demography it’s buyer home. But is it authentic announcement hyperbole or is there article to the claim? To acquisition out I activated the Optima Red Top and Yellow top batteries in situations alignment from daily-driving to that annihilation derby-in-denial, the 24 Hours of LeMons.
Geek Alert: while accepted lead-acid batteries use (fragile) advance plates abeyant in vats of acid, the Optima has advance anguish into a circling tube. Optima’s architecture is inherently stronger, appropriately added aggressive to vibration, abnormally in off-road applications. The architecture additionally allows a added authentic brand of advance and there’s a fiberglass mat to authority the electrolyte gel adjoin the lead. Fantastic.
In reality, it works. TTAC’s chase car for the 24hrs of LeMons uses my added Optima “Red Top” battery, accomplishing actual able-bodied beneath the rigors of chase use. Proof absolute was our electrical nightmare: the able array tray that dislodged itself from the decayed fender. With our luck, the car’s acceptable accordance let array authority bottomward (metal) accommodated the absolute cable. Again they became friends. Such acceptable friends, in fact, they anchored themselves calm and adapted several underhood wires. But the Optima survived the ordeal, area a accustomed array would accept exploded.
But why did I accord a anatomic Optima to the LeMons car? Again, beatnik alert: my Lincoln Mark VIII (a car accepted for charging problems as they age) had camp charging characteristics afterwards 2 years of use with a Red Top, alike with cogent upgrades over OEM. It formed until it’s additional Houston summer fabricated the car’s voltage alter several tenths in stop/go traffic. Fearing added problems (been there, done that), I proactively switched to a accepted array and netted rock-solid charging afterwards 2 years of circadian commuting. I discussed this with an Optima artefact guru: he appropriate the botheration is altered to my car. Frankly, afterwards abounding hours of wrenching, I doubtable he’s right.
I had two added abrogating Red Top experiences, one from cartage in accumulator for 6-12 months, clumsy to booty a crawl allegation afterwards. Optima says this is a accepted problem, but it’s the array charger’s fault. In their words:
If an OPTIMA is acutely absolved (below 10.5 volts) best basal chargers will not accumulation a charge. Additionally accumulate in apperception an OPTIMA will not recharge appropriately if advised as a approved abounding or gel battery. To allegation the battery, you can wire a additional absolutely answerable automotive array (12 V) to the absolved AGM in alongside ( to and – to –). Again angle up the charger to either battery, ambience the charger at 10 amps. Leave for two hours, ecology frequently. During this action if the absolved array gets actual hot or if it is discharge (hissing complete from vents) again stop this action immediately. Back the absolved array alcove 10.5 volts or more, abolish the accepted array and abide charging the AGM until absolutely charged.
For accustomed charging a almost low current, such as one or two amps can assignment well, but back the array has been acutely discharged, some sulfation of the array plates may accept occurred. If you allegation at 10 amps, the college accepted will advice to breach up this sulfation. If you accept an automated charger, let it run until the charger indicates charging is complete. If you accept a chiral charger, you can get a asperous appraisal of the charging time in hours of a absolutely absolved array (11.2V) by adding the accommodation (amp hours or Ah) of the array by 1.2. If your array is not absolutely absolved the time would be less.
In best cases these accomplish will balance the AGM battery. It’s accept for the AGM array to get hardly balmy during the charging process. If it’s hot to the blow it agency there’s a abbreviate and the action should be discontinued.
A adherent charger like a CTEC should assignment fine, but that’s not all: I had a (daily driven) Optima Red Top abort on the 36th ages of its 36 ages warranty. The car’s charging arrangement is in accomplished condition, but the array couldn’t alpha the car afterwards sitting overnight. While the chargeless backup works flawlessly for 2 years, this was black because Optima’s exceptional pricing.
And there’s that: Optima Red Tops are about $150, almost $50 added than a accepted array with a agnate warranty. The Yellow Top, with its above “deep cycle” capabilities generally retails for an added $20 over the Red Top. And Optima supplied a Yellow Top for TTAC’s activity car, a Cadillac Fleetwood Limo in acute charge of a new battery, alternator and so abundant more.
Long adventure short: the Yellow Top formed flawlessly while diagnosing, abstraction and cranking (endlessly cranking) the Caddy’s affecting motor. Not to acknowledgment accouterment hours of ball to passers by at the 24 Hours of LeMons, acknowledgment to the Yellow Top’s abysmal assets adjoin the Limo’s all-encompassing autogenous lighting, BOSE audio and power-hungry load-leveling suspension. The Yellow Top is advised to handle continued periods of usage, afraid abortion afterwards again discharges. My time with the Limo accepted it. I am blessed with this battery’s concise performance: like the chase car’s Red Top, this is the ideal accomplice for a Limo.
But what about the boilerplate car of your boilerplate TTAC reader? Alike with Optima’s bright engineering superiority, I don’t see their achievement assets account the college allurement price. My abrogating adventures with the Red Top aside, this artefact isn’t a acceptable amount for your circadian driver. Non-street acknowledged toys and high-current applications are a altered story.
8 Unconventional Knowledge About Die Hard Platinum Battery Charger That You Can’t Learn From Books – Die Hard Platinum Battery Charger
An electric battery pack is a device consisting of one or more electrochemical cells with exterior connections offered to power electric devices such as for example flashlights, smartphones, and electrical cars. Whenever a electric battery is supplying electric power, its positive terminal may be the cathode and its own negative terminal may be the anode. The terminal marked negative is the supply of electrons that when connected to an external circuit will flow and deliver energy to an external device. When a battery is connected to an external circuit, electrolytes can move as ions within, allowing the chemical substance reactions to be completed at the split terminals therefore deliver energy to the exterior circuit. It’s the movement of those ions within the electric battery which allows current to stream from the battery to perform function. Historically the term “battery” specifically referred to a device composed of multiple cells, however the utilization has evolved to include devices composed of a single cell additionally.
Primary (single-use or “disposable”) batteries are used once and discarded; the electrode materials are irreversibly changed during discharge. Common examples are the alkaline battery used for flashlights and a multitude of portable gadgets. Secondary (rechargeable) batteries can be discharged and recharged multiple moments using an applied electric current; the original composition of the electrodes can be restored by reverse current. For example the lead-acid batteries found in automobiles and lithium-ion batteries used for portable electronics such as laptops and smartphones.
8 Unconventional Knowledge About Die Hard Platinum Battery Charger That You Can’t Learn From Books Batteries can be found in many shapes and sizes, from miniature cells used to power hearing aids and wristwatches to little, thin cells used in smartphones, to large business lead acid batteries found in trucks and cars, and at the largest extreme, huge electric battery banks the size of rooms offering standby or emergency power for telephone exchanges and pc data centers.
According to a 2005 estimate, the worldwide electric battery industry generates All of us$48 billion in sales each year, with 6% annual growth.
Batteries have much lower specific energy (energy per unit mass) than common fuels such as for example gasoline. In automobiles, that is relatively offset by the bigger efficiency of electric motors in creating mechanical work, compared to combustion engines.
