            A:  Hello, Gpgp - Thank you for your interest in the 40V Lithium-Ion 5.0 Ah Battery. As stated on page 2 in the manual; For battery pack storage longer than 30 days. store the battery pack where the temperature is below 80°F and away from moisture. Store battery packs in a 30%-50% charged condition. Every six months of storage, charge the pack as normal Additionally, if you need further support, then a RYOBI Customer Experience Professional is here for you, Monday - Friday from 9 am to 6 pm (EST) when you call or text us at 1.800.525.2579 or through email or live chat when you visit us at https://www.ryobitools.com/support/contact.

                Q:I need to replace a Ryobi 40V 2.6 AH LI-ION battery for the hedge trimmer I bought only 2 years ago. HD only lists the 5AH online. Is the 2.6 AH available, and if not, when will it be available? The Ryobi web site only states that it is "coming soon".

                Answer This Question

                A:  You need to just call Home Depot online sales & ask them directly. This is an availability question they should answer directly, but instead they've just sent it out to past purchasers to answer, which we would have no clue on the availability! Personally, the 5 AH lasts longer, but I always wait for them to be on sale before purchasing, because regular price is far too expensive. You also need to call to see if you can get some credit for battery dieing after only 2 yrs, because all of my 40v batteries have lasted atleast 7+ yrs.

                    A:  Hello, Warren - Thank you for your interest in the 40V Lithium-Ion 5.0 Ah Battery. The 2.6 amp hour battery is no longer being made. If your tool is 40 volt then you can use any 40 volt battery.  Additionally, if you need further support, then a RYOBI Customer Experience Professional is here for you, Monday - Friday from 9 am to 6 pm (EST) when you call or text us at 1.800.525.2579 or through email or live chat when you visit us at https://www.ryobitools.com/support/contact.

                      A:  Have no idea. All I have is spare 5AH batteries for all my 40V tools I found that size was better on this trimmer, because it counterbalanced to heavy cutter head and of course lasted much longer.

                        A:  You can use the one with 5 amps. It just will hold a longer charge.

                          This is my second Ryobi battery and they work great with my mower and vacuum. They also don't take very long to charge either. A bit pricey but I think they are worth it.

                              Good News/Bad News - and a word of caution
                              Bought op4050 (5 amp) model because my 2-year old 2.6 amp battery would only run chainsaw for 15 minutes. Charged my new battery overnight and it ran for... 8 minutes! Good news is that warranty 800 operator was friendly and is shipping me a new battery. Bad news is still have to wait two more weeks for a decent battery. Date code incidated battery was produced 15 months ago. This again confirms lessons I have painfully learned about Ryobi batteries. If you buy from anyone other than Home Depot, Ryobi WILL NOT honor a warranty. It sucks how expensive these batteries are, but bite the bullet, but from Depot, and keep your receipt and order number for the full three years.

                                  BATTERY NEEDS IMPROVEMENT such as thermal management ,over load protection
                                  I used this battery for about 2 years for lawn mower and cutting tree branches. Good and strong power. Easy to recharge and satisfactory amount of time last long. After I used with 14 in chainsaw and cut the 7 inchs tree root, battery was unable to recharge and defective . I don't have problem with 4-5 inches tree branches.

                                    I have 4 tools, leaf blower, weed trimmer, leaf vac, and chainsaw that run off of this type of battery, Within 1-2 years of purchasing these tools/batteries online and some from the home depot store, only one (1) of the four (4) batteries work good, two have failed completly, and 1 only works 2-3min now, the only good one lasts me about 15min. There’s no reason why these batteries should have failed so quickly. Ryobi need to fix their faulty batteries.

                                      i have the Ryobi lawn mower, weed eater and blower all three batteries absolutely suck. All 3 can't keep a charge.
