is it 1.5 a ph or 3 for the battery? and if it is a 1.5 is it okay to buy a new battery that is 2.5 or 3.0?

I believe what you are asking is if it is 1.5 (ah) amp hour is it ok to replace with a 3.0 amp hour battery. Yes,as long as they are the same voltage. Amp hour only relates to how long the tool will run on a full charge.

It is 6.8, but none of the 2 batteries that I have hold a candle to the Sony one. The real Sony ones lasts for days and the other 2 I have don't hold well at all.

Hi Linda. I'm no expert, but our old battery was 4.0Ah too. We bought this one, the 5.0Ah and replaced the old battery with the 5.0Ah. The hardest thing for me to do was unscrew the screws so I could get the cover off the front of the alarm box. :-) The new battery fit in the same space as the old battery. It's been almost exactly a year since we got the new battery and we haven't had any trouble at all. I hope this helps you. Kathy

I think the volts (V) is the number that needs to match but the mAh does not. In fact, if the mAh number is higher than the original battery, you should notice improved performance.

The current battery my wife is using is rated at 3.7 VDC 4300 mAhrs (extended life battery purchased through WirelessEmporium.com on Nov. 12, 2012). The new battery is rated at 3.7 VDC 4200 mAhrs. (Hyperion) We have not used the new battery yet. All batteries run hotter when using the GPS (both in Android and iPhones). This is due to additional power usage from more chips coming into play. One-tenth of a volt is not significant to make a difference in temperature. Your battery voltage will drop up to 0.8 volts from full charge to low charge values (Li-Ion or Li-Polymer batteries). The more power use you call upon the more current flow occurs (amperage). With all else remaining the same (resistance values of circuit traces, electronic components, etc.), the more heat you will get out of any electronic component. You will always feel it with your cell phone. The formula is W=I(squared)R. This means as resistance remains the same (R), and current increases (I) power will increase with the value of the current squared! Power produces heat in resistors or any resistive device. Therefore your phone will get hot. If you want to view the power formula involving voltage, it is W=EI. So as battery voltage drops current will increase to maintain power at the same level. So as your battery value decrease you have a linear relational change in current increasing. Again this will produce some heat increase but it will be insignificant compared with the additional current draw to bringing more components into play which are a squared relationship.

It could be labeled as 2AH. Smaller batteries such as these are traditionally labeled in mAh.

My battery says 10.8 on it, so that is what I would trust. I think that it has something to do with multiplications with how many cells there are, yada yada...I did a lot of research when I was making my purchase, and I probably used to know the technical answer, but I've forgotten. But the other thing I learned was that the voltage doesn't really matter that much, as long as you're moving down rather than up (obviously if you move up you could blow something out). My old battery, the one that came with the laptop, was 14.4, and now I have a 10.8...which has worked flawlessly with no problems. See, my old battery was 14.4v, 2600 mAH...which, you multiply those two numbers to actually find an approximation of how long the charge will last vs. other batteries. This battery is 10.8v, but has 5200mAH, so it actually lasts a lot longer than my old one. So: I highly recommend it. It works perfectly, has a quite long battery life, and even after much abuse by me (accidentally letting it drain all the way down over 100 times) it STILL has a pretty good battery life.

Apparently it depends upon which vendor you choose to purchase from on Amazon. My original battery had 8850 maH capacity, just like Andrew mentions below. However, the battery that I received has only 7650 maHs of capacity so I'm debating whether to return it. The part number for my original battery is 636631-001 while the new battery is 593550-001 but appears to be new and a genuine HP part. Apparently HP has offered multiple batteries with different part numbers as a MU09 battery. I purchased my battery from Amazon through Mobile Parts Pro. I'm curious to compare the capacity of batteries purchased from other vendors under this same Amazon item number. Apparently it depends upon which vendor you choose to purchase from on Amazon.

Bear in mind that if you take this battery below 8.5 v you will damage the battery and void the warranty. I would suggest giving yourself a safety margin of a larger battery so that you don't run the risk of inadvertently damaging it. The BTL35A480C has a Pb Eq of 26~35Ah and has the biggest saving over MRSP of $64 if you purchase from Amazon. Be sure to get the correct charger.

Be very careful about changing your PH. Do it in little increments . If it's at 7 just leave it at that

It didn't say that it wasn't new when i purchased the battery. I assumed that it was new. It sure doesnt work like a new battery though. It is better (slightly) than a dying battery which is what a had at the time. So, if you looking for a slight upgrade for the cost; it is a good deal.

None. It is solar I guess it does take the 1.5. I have never changed a battery

Get at least the 2.0 amp hour battery. The 2.0 runs me about 1/2 to 3/4 a day of use. I would entertain the thought of the 4.0, but pricing and bulkiness dissuaded me. You can get 2 2.0 batteries for the price of one 4.0 last I checked.

Thanks! It's good to know, just for an emergency. I've run my Nextgen unit for about 5 years using 2 of their 2/3 batteries. I keep one in the unit and every month or so swap them.

Hey there. I had bought this for a friend. From what I can remember it's 3.5 hope this helps.

I have been using 312 batteries for almost four years and they were all 1.45v. I'm sure in the description it was just and omission of a 5.

Good luck getting a straight answer from the seller on this. I can tell you that I recently bought one of these and it was a really solid improvement over my old battery. Tough to compare because it's been 2.5 years since my original battery was new, but I don't think the new replacement is quite as good as the original when it was new.
